Reports from the ProjectsArVOAstroGridWe announced (1 Apr 2008) our release of the AstroGrid Desktop Suite : get it from http://www.astrogrid.org This was time to coincide with the UK National Astronomy meeting in Belfast. After various prototypes over several years, this is the first release of a complete set of software and working services. From the user's point of view we released three applications that run on the desktop - VODesktop; Topcat; and AstroGrid Python - and provided links to other Euro-VO tools that interoperate seamlessly - Aladin, VOSpec, SPLAT-VO. We also link to other VO tools - NVO services, VOPlot, etc. In the background we are operating a number of services - Registry, VOSpace, and Community - in several sites - and we have used our own DSA component to help UK data centres establish working data services. Of course VODesktop also provides access to the thousands of services worldwideAustralia-VOChina-VODuring the last 3 months, we have been looking for all kinds of funding possibilities. Although, supported by the LAMOST project, the China-VO is always active. Currently, there are 4 topics from our group. The first one is VO-DAS, which will be released to the community in June with support of several big datasets including SDSS DR6 (BestDR6 and SegueDR6), TwoMASS and GSC 2.2. The second one is a MatLab toolkit named AstroBox. We completed a PLASTIC module for MatLab so that it can work together with other VO tools. We plan to collect popular statistic and data mining algorithms into the AstroBox. So, astronomers can use it easily on MatLab platform. The third one is LAMOST archive system. It is a long-term but core task for the China-VO. And the forth work is development of a new version of FitHAS, the small FITS file DB importer.CVOEuro-VOThe EuroVO-DCA project has performed a census of astronomical data centres in European countries. Information about the census objectives and the census questionnaire can be found here. More than 65 data centres in a total of 14 different countries have answered. Two workshops about 'Theory in the VO' and 'Grid and the VO' were organised in the framework of the EuroVO-DCA project in MPE, Garching, by GAVO and and VObs.it (Trieste) respectively, with several participants from other VO projects. They led to interesting discussions, which will in particular be very useful in the definition of the SNAP protocol and for the Astro-RG Interest Group. The Euro-VO Astronomical Infrastructure for Data Access (EuroVO-AIDA) project started on February 1st for a duration of 30 months. Detailed information on the project can be found in the project TWiki http://cds.u-strasbg.fr/twikiAIDA/bin/view/EuroVOAIDA/WebHome. The Euro-VO project, in the framework of AIDA (Astronomical Infrastructure for Data Access), has launched a call for proposals for teams carrying out archival research or projects that could benefit from the Virtual Observatory concept. Successful applicants will receive support from EURO-VO astronomers in using the VO facilities and software to complete their projects. No direct funding is awarded in this programme, but support for travel to VO centres may be available if justified by the project. More details can be found at http://www.euro-vo.org/pub/fc/AIDA_call_2008.html. The registration period for the Euro-VO Workshop on "How to Publish Data in the VO", to be held at ESO June 23 - 27, is now open. The workshop is geared towards data centres and large projects to enable them to acquire the knowledge and experience necessary to publish catalogues, data products and other resources to the Virtual Observatory. More details can be found at http://www.euro-vo.org/dcaworkshop2008/France VOSince no France-VO report was posted on TM26 web page, this report summarizes the activities since the Exec face-to-face meeting held in Cambridge in September 2007 (FM25). The annual meeting of France-VO was held in Paris on 26-27 November 2007, with ~60 participants. Most French Observatories were represented. The lively presentations (mostly in French) and discussions showed the variety of VO-compliant services in development or at maturity, of technical programs (interoperability standards, workflows) which are presently under way in France, and some examples of science usages. Two topical meetings have also been organised under F-VO auspices:
GAVOHVOJapan-VOWe have successfully implemented the JVO portal system since 2008 March. Visit at http://jvo.nao.ac.jp/portal/. Anyone can access and dowload the observed data from more than 1,300 site in the world. More than 1 TBytes of data have already downloaded. We implemented a prototype for a workflow builder system based on the Taverna in order to easily construct data query and data analysis processes on a graphical user interface. Similar system has also been built in the UK, and we plan to compare our systems toward better, common system. Some project members were invited to give talks on the virtual observatory in several international meetings. It should be noted that the Core-to-Core program members published 104 academic papers, incuding 8 invited talks. We were informed that the Core-to-Core program of the JSPS will continue its support to the JVO for the fiscal year 2008 (April 2008 to March 2009).Korean VONVORVOSVO

VObs.it has been funded by INAF for 2008, even though at an unsatisfactory level: there are funds to cover the May 08 Interop meeting, for travel and for two contracts related to VO activities (in Milan and in Teramo). Additional resources are received through the EU-funded projects (VO-Tech and VO-DCA).
A proposal was prepared to build an integrated e-infrastructure for astrophysics (centered on VObs.it and computing resources) as part of a roadmap for scientific infrastructures to be submitted to the national Ministry of Research (MIUR). The proposal was not supported by INAF and did not reach MIUR.
IA2 continues its collaboration with Heidelberg and Tucson to build a VO-compliant LBT-wide archive; a position for this work is being filled.
Work is continuing within the EU-funded VO-Tech and VO-DCA projects. Two workshops, on Theory in the VO and on Grid and the VO, were co-organised by INAF/VObs.it and MPE/GAVO in the framework of the VO-DCA project, and held back-to-back in Garching during the week from April 7th to 11th (http://www.si.inaf.it/eurovow2008/index.htm). The meetings were well attended (over 70 participants) and successful, judging by the interest evidenced in the discussions.
VO-IndiaReports from WGs & IGs(follows order as at http://www.ivoa.net/forum/)Applications WGSAMP - Simple Applications Messaging Protocol is in a period of intense discussion within the lead authors of the specification. A draft document is expected to be posted for wider discussion in preparation for the SAMP sessions in Trieste. A program of presentations of applications/tools/services is being prepared for the Trieste meeting. These presentations are intended to show and discuss implentations of VO standards. Discussion on how to better communicate the capabilities of VO applications to the astronomy community is also being planned.Data Access Layer WGThe DAL WG is actively involved the following areas: | |||||||||||

The main activity for the GWS working group over the past few months has been VOSpace 1.1. A working draft of the specification, WSDL and schema was released on 16 January 2008. Reference implementations have been/are under development at Caltech, UCSD, JHU, Astrogrid and CDS. At least one of these (UCSD) also interfaces with the iRODS software from SDSC. There has also been work on the VOSpace usage document (Harrison, Morris) which describes the core metadata terms that we will be registering.
Members of the WG have been looking at security issues, including delegation (Rixon, Graham), particularly with a view to a more RESTful approach; and authorisation (Graham).
There has also been work on VOSI (Rixon) and CEA/UWS (Harrison).
Registry WGOur primary effort has been in effecting the transition to the v1.0 standard for Registry Interfaces. We set a date of 21 April as the official start of v1.0 harvesting by which all nearly-ready registries should be ready by; all of those registries are now up and registered with the Registry of Registries (see http://rofr.ivoa.net/ for a list). Not included in this first round of compliant registries is the ESAC registry which we knew would require approx. 1 month of additional work. When this registry is ready, integration via the RofR should be transparent. The start of v1.0 registry harvesting this week will allow us several weeks of experience harvesting the new records and to uncover any remaining problems that might be discussed at Trieste. We note that AstroGrid, with its recent product release, has been operating their registries at the v1.0 standard for some time now. Prior to this week, they have used kept a cache of v1.0 records that they converted themselves from the old format records from the registries that were not ready yet. The transition should be seemless. The authors of the Outreach Metadata proposal, previously issued as an IVOA Note (http://www.ivoa.net/Documents/latest/AOIMetadata.html), have developed a revised version and have been actively engaging the outreach community for comments. This new version is currently be reformatted into a Working Draft. Once submitted to me, I will release it to the document repository, and develop a twiki discussion page. Their efforts have not gone unnoticed among alert IVOA people, and there is growing interest in this document (from Semantics and DM). The authors would like to encourage the development of prototypes and path-finder applications using this document. After a 6-month development period along with general discussion, we expect to hold a Registry WG session at the Baltimore IVOA meeting to discuss in detail the future of this document in the IVOA. Now that the long-delayed upgrade effort is (nearly) behind us, we are interested in moving remaining documents through the process, and begin considering advanced discovery and harvesting techniques. An important leading issue is the mechanism for harvesting detail metadata about services from the services themselves.Semantics/UCD WGVocabularies: A WD v1.0 on Vocabularies in the Virtual Observatory has been published recently (March 20, 2008). The WD is the result of a lively discussion, and it seems ready to move on to PR status in May. Cross-matching between vocabularies and use cases are the current open issues, and they will be debated in the coming InterOpMay2008.VOEventVOQL WGVOTable WGAstro-RG IG
Data Curation and Preservation IGTheory IGSNAP divided into 2 separate but llinked projects: Simulation Database (SimDB) and Simulation Data Access Protocol (SimDAP). SimDB has had lots of activity, visible for now on http://volute.googlecode.com/svn/trunk/projects/theory/snapdm/. It is ready for promotion to "standardisation" process, likely in DM WG. An IVOA Note detailing the proposed project and describing its current status will be ready for Trieste, where this will be discussed further. It might be interesting for the exec to discuss the process of how projects get turned into a standardisation project and who should be responsible. In particular the SimDB project has relations to other WGs: Registry, ADQL, DAL(TAP) Semantics. It suggests a structure where it is possible that small groups ("tiger teams") are created for standards development projects, that are not within the scope of a single WG. Such a group could act as a temporary WG and be made responsible for the whole process up to and including RFC of that project. SimDAP is being restarted with Claudio Gheller and Rick Wagner as main drivers and we hope it to be ready to be moved up to standardisation status-- NicholasWalton - 14 Jan 2008

The registration period for the Euro-VO Workshop on "How to Publish Data in the VO", to be held at ESO June 23 - 27, is now open. The workshop is geared towards data centres and large projects to enable them to acquire the knowledge and experience necessary to publish catalogues, data products and other resources to the Virtual Observatory. More details can be found at http://www.euro-vo.org/dcaworkshop2008/France VOSince no France-VO report was posted on TM26 web page, this report summarizes the activities since the Exec face-to-face meeting held in Cambridge in September 2007 (FM25). The annual meeting of France-VO was held in Paris on 26-27 November 2007, with ~60 participants. Most French Observatories were represented. The lively presentations (mostly in French) and discussions showed the variety of VO-compliant services in development or at maturity, of technical programs (interoperability standards, workflows) which are presently under way in France, and some examples of science usages. Two topical meetings have also been organised under F-VO auspices:

Some project members were invited to give talks on the virtual observatory in several international meetings. It should be noted that the Core-to-Core program members published 104 academic papers, incuding 8 invited talks. We were informed that the Core-to-Core program of the JSPS will continue its support to the JVO for the fiscal year 2008 (April 2008 to March 2009).
Korean VONVOWe will update this with the summary from our quarterly report, which will be completed in early May. We submitted a proposal to NSF and NASA on April 22 for the VAO Facility. The funding request is for five years. NVO will be rechristened VAO -- the Virtual Astronomical Observatory -- and will be managed by a new corporate entity, the VAO, LLC. This all assuming, of course, that our proposal is selected for funding.RVOSVO
VObs.itThe local arrangements for the May 08 Interop meeting in Trieste (May 18th to 23rd at the “Stazione Marittima” congress centre) are being completed. Info are available on the IVOA wiki (http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/InterOpMay2008) and on the local Web site dedicated to the meeting (http://www.si.inaf.it/ivoa_interop_2008/). Most of the logistics have been settled, an upgrade to the wi-fi provided by the congress centre is being set up. The company providing the booking for participants has proven to be not completely adequate: potential participants are encouraged to register as soon as possible. VObs.it has been funded by INAF for 2008, even though at an unsatisfactory level: there are funds to cover the May 08 Interop meeting, for travel and for two contracts related to VO activities (in Milan and in Teramo). Additional resources are received through the EU-funded projects (VO-Tech and VO-DCA). A proposal was prepared to build an integrated e-infrastructure for astrophysics (centered on VObs.it and computing resources) as part of a roadmap for scientific infrastructures to be submitted to the national Ministry of Research (MIUR). The proposal was not supported by INAF and did not reach MIUR. IA2 continues its collaboration with Heidelberg and Tucson to build a VO-compliant LBT-wide archive; a position for this work is being filled. Work is continuing within the EU-funded VO-Tech and VO-DCA projects. Two workshops, on Theory in the VO and on Grid and the VO, were co-organised by INAF/VObs.it and MPE/GAVO in the framework of the VO-DCA project, and held back-to-back in Garching during the week from April 7th to 11th (http://www.si.inaf.it/eurovow2008/index.htm). The meetings were well attended (over 70 participants) and successful, judging by the interest evidenced in the discussions.VO-IndiaReports from WGs & IGs(follows order as at http://www.ivoa.net/forum/)Applications WGSAMP - Simple Applications Messaging Protocol is in a period of intense discussion within the lead authors of the specification. A draft document is expected to be posted for wider discussion in preparation for the SAMP sessions in Trieste. A program of presentations of applications/tools/services is being prepared for the Trieste meeting. These presentations are intended to show and discuss implentations of VO standards. Discussion on how to better communicate the capabilities of VO applications to the astronomy community is also being planned.Data Access Layer WGThe DAL WG is actively involved the following areas:
Interaction with Registry Working GroupWe are especially interested in the Registry WG schema for Service Registration and the various Resource schemata as they present opportunities for DAL services to exploit.Interaction with Grid and Web Services Working GroupVOSI is of particular importance to DAL services, especially Capabilities and Availability. By their nature, DAL services typically need monitoring by systems administrators, so the work on Availability will be most relevant.Data Models WG (MireilleLouys)From the last Interop in september 2007, the DM working group was involved in the following :
Interaction with the Theory IG :
Models in action :
Grid and Web Services Working Group (MatthewGraham)The main activity for the GWS working group over the past few months has been VOSpace 1.1. A working draft of the specification, WSDL and schema was released on 16 January 2008. Reference implementations have been/are under development at Caltech, UCSD, JHU, Astrogrid and CDS. At least one of these (UCSD) also interfaces with the iRODS software from SDSC. There has also been work on the VOSpace usage document (Harrison, Morris) which describes the core metadata terms that we will be registering. Members of the WG have been looking at security issues, including delegation (Rixon, Graham), particularly with a view to a more RESTful approach; and authorisation (Graham). There has also been work on VOSI (Rixon) and CEA/UWS (Harrison).Registry WGOur primary effort has been in effecting the transition to the v1.0 standard for Registry Interfaces. We set a date of 21 April as the official start of v1.0 harvesting by which all nearly-ready registries should be ready by; all of those registries are now up and registered with the Registry of Registries (see http://rofr.ivoa.net/ for a list). Not included in this first round of compliant registries is the ESAC registry which we knew would require approx. 1 month of additional work. When this registry is ready, integration via the RofR should be transparent. The start of v1.0 registry harvesting this week will allow us several weeks of experience harvesting the new records and to uncover any remaining problems that might be discussed at Trieste. We note that AstroGrid, with its recent product release, has been operating their registries at the v1.0 standard for some time now. Prior to this week, they have used kept a cache of v1.0 records that they converted themselves from the old format records from the registries that were not ready yet. The transition should be seemless. The authors of the Outreach Metadata proposal, previously issued as an IVOA Note (http://www.ivoa.net/Documents/latest/AOIMetadata.html), have developed a revised version and have been actively engaging the outreach community for comments. This new version is currently be reformatted into a Working Draft. Once submitted to me, I will release it to the document repository, and develop a twiki discussion page. Their efforts have not gone unnoticed among alert IVOA people, and there is growing interest in this document (from Semantics and DM). The authors would like to encourage the development of prototypes and path-finder applications using this document. After a 6-month development period along with general discussion, we expect to hold a Registry WG session at the Baltimore IVOA meeting to discuss in detail the future of this document in the IVOA. Now that the long-delayed upgrade effort is (nearly) behind us, we are interested in moving remaining documents through the process, and begin considering advanced discovery and harvesting techniques. An important leading issue is the mechanism for harvesting detail metadata about services from the services themselves.Semantics/UCD WGVocabularies: A WD v1.0 on Vocabularies in the Virtual Observatory has been published recently (March 20, 2008). The WD is the result of a lively discussion, and it seems ready to move on to PR status in May. Cross-matching between vocabularies and use cases are the current open issues, and they will be debated in the coming InterOpMay2008.VOEventThere are discussions with several new groups, who hopefully will submit their transients using VOEvent: these are the MOA project in New Zealand, the Supernova Factory in Berkeley, and the Murchison Widefield Array in Australia. In Trieste, we hope to make progress on registering VOEvent nodes, so that any event ID can be resolved using VO protocol. We are also interested in digital signatures for events, and in defining parameter names and UCDs as standards.VOQL WGVOTable WGIt was decided at the Beijing meeting to write an IVOA note about "Referencing the STC in VOTable" co-written by FrancoisOchsenbein, JonathanMcDowell and ArnoldRots; this note was written but no consensus could be reached up to now.Astro-RG IG
Data Curation and Preservation IGThe DC&P IG will have a session at the upcoming Interop in Trieste. The NVO is collaborating with the JHU Library on a proposal to NSF's Datanet program for multi-disciplinary long-term preservation and curation of data. The proposal has survived the first two rounds of the selection process and is proceeding to a third and final round, a site visit.Theory IGSNAP divided into 2 separate but llinked projects: Simulation Database (SimDB) and Simulation Data Access Protocol (SimDAP). SimDB has had lots of activity, visible for now on http://volute.googlecode.com/svn/trunk/projects/theory/snapdm/. It is ready for promotion to "standardisation" process, likely in DM WG. An IVOA Note detailing the proposed project and describing its current status will be ready for Trieste, where this will be discussed further. It might be interesting for the exec to discuss the process of how projects get turned into a standardisation project and who should be responsible. In particular the SimDB project has relations to other WGs: Registry, ADQL, DAL(TAP) Semantics. It suggests a structure where it is possible that small groups ("tiger teams") are created for standards development projects, that are not within the scope of a single WG. Such a group could act as a temporary WG and be made responsible for the whole process up to and including RFC of that project. SimDAP is being restarted with Claudio Gheller and Rick Wagner as main drivers and we hope it to be ready to be moved up to standardisation status-- NicholasWalton - 14 Jan 2008 <--

Reports from the ProjectsArVOAstroGridWe announced (1 Apr 2008) our release of the AstroGrid Desktop Suite : get it from http://www.astrogrid.org This was time to coincide with the UK National Astronomy meeting in Belfast. After various prototypes over several years, this is the first release of a complete set of software and working services. From the user's point of view we released three applications that run on the desktop - VODesktop; Topcat; and AstroGrid Python - and provided links to other Euro-VO tools that interoperate seamlessly - Aladin, VOSpec, SPLAT-VO. We also link to other VO tools - NVO services, VOPlot, etc. In the background we are operating a number of services - Registry, VOSpace, and Community - in several sites - and we have used our own DSA component to help UK data centres establish working data services. Of course VODesktop also provides access to the thousands of services worldwideAustralia-VOChina-VODuring the last 3 months, we have been looking for all kinds of funding possibilities. Although, supported by the LAMOST project, the China-VO is always active. Currently, there are 4 topics from our group. The first one is VO-DAS, which will be released to the community in June with support of several big datasets including SDSS DR6 (BestDR6 and SegueDR6), TwoMASS and GSC 2.2. The second one is a MatLab toolkit named AstroBox. We completed a PLASTIC module for MatLab so that it can work together with other VO tools. We plan to collect popular statistic and data mining algorithms into the AstroBox. So, astronomers can use it easily on MatLab platform. The third one is LAMOST archive system. It is a long-term but core task for the China-VO. And the forth work is development of a new version of FitHAS, the small FITS file DB importer.CVOEuro-VOThe EuroVO-DCA project has performed a census of astronomical data centres in European countries. Information about the census objectives and the census questionnaire can be found here. More than 65 data centres in a total of 14 different countries have answered. Two workshops about 'Theory in the VO' and 'Grid and the VO' were organised in the framework of the EuroVO-DCA project in MPE, Garching, by GAVO and and VObs.it (Trieste) respectively, with several participants from other VO projects. They led to interesting discussions, which will in particular be very useful in the definition of the SNAP protocol and for the Astro-RG Interest Group. The Euro-VO Astronomical Infrastructure for Data Access (EuroVO-AIDA) project started on February 1st for a duration of 30 months. Detailed information on the project can be found in the project TWiki http://cds.u-strasbg.fr/twikiAIDA/bin/view/EuroVOAIDA/WebHome. The Euro-VO project, in the framework of AIDA (Astronomical Infrastructure for Data Access), has launched a call for proposals for teams carrying out archival research or projects that could benefit from the Virtual Observatory concept. Successful applicants will receive support from EURO-VO astronomers in using the VO facilities and software to complete their projects. No direct funding is awarded in this programme, but support for travel to VO centres may be available if justified by the project.

A proposal was prepared to build an integrated e-infrastructure for astrophysics (centered on VObs.it and computing resources) as part of a roadmap for scientific infrastructures to be submitted to the national Ministry of Research (MIUR). The proposal was not supported by INAF and did not reach MIUR. IA2 continues its collaboration with Heidelberg and Tucson to build a VO-compliant LBT-wide archive; a position for this work is being filled. Work is continuing within the EU-funded VO-Tech and VO-DCA projects. Two workshops, on Theory in the VO and on Grid and the VO, were co-organised by INAF/VObs.it and MPE/GAVO in the framework of the VO-DCA project, and held back-to-back in Garching during the week from April 7th to 11th (http://www.si.inaf.it/eurovow2008/index.htm). The meetings were well attended (over 70 participants) and successful, judging by the interest evidenced in the discussions.VO-IndiaReports from WGs & IGs(follows order as at http://www.ivoa.net/forum/)Applications WGSAMP - Simple Applications Messaging Protocol is in a period of intense discussion within the lead authors of the specification. A draft document is expected to be posted for wider discussion in preparation for the SAMP sessions in Trieste. A program of presentations of applications/tools/services is being prepared for the Trieste meeting. These presentations are intended to show and discuss implentations of VO standards. Discussion on how to better communicate the capabilities of VO applications to the astronomy community is also being planned.Data Access Layer WGThe DAL WG is actively involved the following areas:
Interaction with Registry Working GroupWe are especially interested in the Registry WG schema for Service Registration and the various Resource schemata as they present opportunities for DAL services to exploit.Interaction with Grid and Web Services Working GroupVOSI is of particular importance to DAL services, especially Capabilities and Availability. By their nature, DAL services typically need monitoring by systems administrators, so the work on Availability will be most relevant.Data Models WG (MireilleLouys)From the last Interop in september 2007, the DM working group was involved in the following :
Interaction with the Theory IG :
Models in action :
Grid and Web Services Working Group (MatthewGraham)The main activity for the GWS working group over the past few months has been VOSpace 1.1. A working draft of the specification, WSDL and schema was released on 16 January 2008. Reference implementations have been/are under development at Caltech, UCSD, JHU, Astrogrid and CDS. At least one of these (UCSD) also interfaces with the iRODS software from SDSC. There has also been work on the VOSpace usage document (Harrison, Morris) which describes the core metadata terms that we will be registering. Members of the WG have been looking at security issues, including delegation (Rixon, Graham), particularly with a view to a more RESTful approach; and authorisation (Graham). There has also been work on VOSI (Rixon) and CEA/UWS (Harrison).Registry WGOur primary effort has been in effecting the transition to the v1.0 standard for Registry Interfaces. We set a date of 21 April as the official start of v1.0 harvesting by which all nearly-ready registries should be ready by; all of those registries are now up and registered with the Registry of Registries (see http://rofr.ivoa.net/ for a list). Not included in this first round of compliant registries is the ESAC registry which we knew would require approx. 1 month of additional work. When this registry is ready, integration via the RofR should be transparent. The start of v1.0 registry harvesting this week will allow us several weeks of experience harvesting the new records and to uncover any remaining problems that might be discussed at Trieste. We note that AstroGrid, with its recent product release, has been operating their registries at the v1.0 standard for some time now. Prior to this week, they have used kept a cache of v1.0 records that they converted themselves from the old format records from the registries that were not ready yet. The transition should be seemless. The authors of the Outreach Metadata proposal, previously issued as an IVOA Note (http://www.ivoa.net/Documents/latest/AOIMetadata.html), have developed a revised version and have been actively engaging the outreach community for comments. This new version is currently be reformatted into a Working Draft. Once submitted to me, I will release it to the document repository, and develop a twiki discussion page. Their efforts have not gone unnoticed among alert IVOA people, and there is growing interest in this document (from Semantics and DM). The authors would like to encourage the development of prototypes and path-finder applications using this document. After a 6-month development period along with general discussion, we expect to hold a Registry WG session at the Baltimore IVOA meeting to discuss in detail the future of this document in the IVOA. Now that the long-delayed upgrade effort is (nearly) behind us, we are interested in moving remaining documents through the process, and begin considering advanced discovery and harvesting techniques. An important leading issue is the mechanism for harvesting detail metadata about services from the services themselves.Semantics/UCD WGVocabularies: A WD v1.0 on Vocabularies in the Virtual Observatory has been published recently (March 20, 2008). The WD is the result of a lively discussion, and it seems ready to move on to PR status in May. Cross-matching between vocabularies and use cases are the current open issues, and they will be debated in the coming InterOpMay2008.VOEventThere are discussions with several new groups, who hopefully will submit their transients using VOEvent: these are the MOA project in New Zealand, the Supernova Factory in Berkeley, and the Murchison Widefield Array in Australia. In Trieste, we hope to make progress on registering VOEvent nodes, so that any event ID can be resolved using VO protocol. We are also interested in digital signatures for events, and in defining parameter names and UCDs as standards.VOQL WGVOTable WGAstro-RG IG
Data Curation and Preservation IGThe DC&P IG will have a session at the upcoming Interop in Trieste. The NVO is collaborating with the JHU Library on a proposal to NSF's Datanet program for multi-disciplinary long-term preservation and curation of data. The proposal has survived the first two rounds of the selection process and is proceeding to a third and final round, a site visit.Theory IGSNAP divided into 2 separate but llinked projects: Simulation Database (SimDB) and Simulation Data Access Protocol (SimDAP). SimDB has had lots of activity, visible for now on http://volute.googlecode.com/svn/trunk/projects/theory/snapdm/. It is ready for promotion to "standardisation" process, likely in DM WG. An IVOA Note detailing the proposed project and describing its current status will be ready for Trieste, where this will be discussed further. It might be interesting for the exec to discuss the process of how projects get turned into a standardisation project and who should be responsible. In particular the SimDB project has relations to other WGs: Registry, ADQL, DAL(TAP) Semantics. It suggests a structure where it is possible that small groups ("tiger teams") are created for standards development projects, that are not within the scope of a single WG. Such a group could act as a temporary WG and be made responsible for the whole process up to and including RFC of that project. SimDAP is being restarted with Claudio Gheller and Rick Wagner as main drivers and we hope it to be ready to be moved up to standardisation status-- NicholasWalton - 14 Jan 2008 <--

LogisticsTelecon:Agenda
Reports from the ProjectsArVOAstroGridWe announced (1 Apr 2008) our release of the AstroGrid Desktop Suite : get it from http://www.astrogrid.org This was time to coincide with the UK National Astronomy meeting in Belfast. After various prototypes over several years, this is the first release of a complete set of software and working services. From the user's point of view we released three applications that run on the desktop - VODesktop; Topcat; and AstroGrid Python - and provided links to other Euro-VO tools that interoperate seamlessly - Aladin, VOSpec, SPLAT-VO. We also link to other VO tools - NVO services, VOPlot, etc. In the background we are operating a number of services - Registry, VOSpace, and Community - in several sites - and we have used our own DSA component to help UK data centres establish working data services. Of course VODesktop also provides access to the thousands of services worldwideAustralia-VOChina-VODuring the last 3 months, we have been looking for all kinds of funding possibilities. Although, supported by the LAMOST project, the China-VO is always active. Currently, there are 4 topics from our group. The first one is VO-DAS, which will be released to the community in June with support of several big datasets including SDSS DR6 (BestDR6 and SegueDR6), TwoMASS and GSC 2.2. The second one is a MatLab toolkit named AstroBox. We completed a PLASTIC module for MatLab so that it can work together with other VO tools. We plan to collect popular statistic and data mining algorithms into the AstroBox. So, astronomers can use it easily on MatLab platform. The third one is LAMOST archive system. It is a long-term but core task for the China-VO. And the forth work is development of a new version of FitHAS, the small FITS file DB importer.CVOEuro-VOThe EuroVO-DCA project has performed a census of astronomical data centres in European countries. Information about the census objectives and the census questionnaire can be found here. More than 65 data centres in a total of 14 different countries have answered. Two workshops about 'Theory in the VO' and 'Grid and the VO' were organised in the framework of the EuroVO-DCA project in MPE, Garching, by GAVO and and VObs.it (Trieste) respectively, with several participants from other VO projects. They led to interesting discussions, which will in particular be very useful in the definition of the SNAP protocol and for the Astro-RG Interest Group. The Euro-VO Astronomical Infrastructure for Data Access (EuroVO-AIDA) project started on February 1st for a duration of 30 months. Detailed information on the project can be found in the project TWiki http://cds.u-strasbg.fr/twikiAIDA/bin/view/EuroVOAIDA/WebHome. The Euro-VO project, in the framework of AIDA (Astronomical Infrastructure for Data Access), has launched a call for proposals for teams carrying out archival research or projects that could benefit from the Virtual Observatory concept. Successful applicants will receive support from EURO-VO astronomers in using the VO facilities and software to complete their projects. No direct funding is awarded in this programme, but support for travel to VO centres may be available if justified by the project. More details can be found at http://www.euro-vo.org/pub/fc/AIDA_call_2008.html. The registration period for the Euro-VO Workshop on "How to Publish Data in the VO", to be held at ESO June 23 - 27, is now open. The workshop is geared towards data centres and large projects to enable them to acquire the knowledge and experience necessary to publish catalogues, data products and other resources to the Virtual Observatory. More details can be found at http://www.euro-vo.org/dcaworkshop2008/France VOSince no France-VO report was posted on TM26 web page, this report summarizes the activities since the Exec face-to-face meeting held in Cambridge in September 2007 (FM25). The annual meeting of France-VO was held in Paris on 26-27 November 2007, with ~60 participants. Most French Observatories were represented. The lively presentations (mostly in French) and discussions showed the variety of VO-compliant services in development or at maturity, of technical programs (interoperability standards, workflows) which are presently under way in France, and some examples of science usages. Two topical meetings have also been organised under F-VO auspices:
GAVOHVOJapan-VOWe have successfully implemented the JVO portal system since 2008 March. Visit at http://jvo.nao.ac.jp/portal/. Anyone can access and dowload the observed data from more than 1,300 site in the world. More than 1 TBytes of data have already downloaded. We implemented a prototype for a workflow builder system based on the Taverna in order to easily construct data query and data analysis processes on a graphical user interface. Similar system has also been built in the UK, and we plan to compare our systems toward better, common system. Some project members were invited to give talks on the virtual observatory in several international meetings. It should be noted that the Core-to-Core program members published 104 academic papers, incuding 8 invited talks. We were informed that the Core-to-Core program of the JSPS will continue its support to the JVO for the fiscal year 2008 (April 2008 to March 2009).Korean VONVO | ||||||||

Reports from the ProjectsArVOAstroGridWe announced (1 Apr 2008) our release of the AstroGrid Desktop Suite : get it from http://www.astrogrid.org This was time to coincide with the UK National Astronomy meeting in Belfast. After various prototypes over several years, this is the first release of a complete set of software and working services. From the user's point of view we released three applications that run on the desktop - VODesktop; Topcat; and AstroGrid Python - and provided links to other Euro-VO tools that interoperate seamlessly - Aladin, VOSpec, SPLAT-VO. We also link to other VO tools - NVO services, VOPlot, etc. In the background we are operating a number of services - Registry, VOSpace, and Community - in several sites - and we have used our own DSA component to help UK data centres establish working data services. Of course VODesktop also provides access to the thousands of services worldwideAustralia-VOChina-VODuring the last 3 months, we have been looking for all kinds of funding possibilities. Although, supported by the LAMOST project, the China-VO is always active. Currently, there are 4 topics from our group. The first one is VO-DAS, which will be released to the community in June with support of several big datasets including SDSS DR6 (BestDR6 and SegueDR6), TwoMASS and GSC 2.2. The second one is a MatLab toolkit named AstroBox. We completed a PLASTIC module for MatLab so that it can work together with other VO tools. We plan to collect popular statistic and data mining algorithms into the AstroBox. So, astronomers can use it easily on MatLab platform. The third one is LAMOST archive system. It is a long-term but core task for the China-VO. And the forth work is development of a new version of FitHAS, the small FITS file DB importer.CVOEuro-VOThe EuroVO-DCA project has performed a census of astronomical data centres in European countries. Information about the census objectives and the census questionnaire can be found here. More than 65 data centres in a total of 14 different countries have answered. Two workshops about 'Theory in the VO' and 'Grid and the VO' were organised in the framework of the EuroVO-DCA project in MPE, Garching, by GAVO and and VObs.it (Trieste) respectively, with several participants from other VO projects. They led to interesting discussions, which will in particular be very useful in the definition of the SNAP protocol and for the Astro-RG Interest Group. The Euro-VO Astronomical Infrastructure for Data Access (EuroVO-AIDA) project started on February 1st for a duration of 30 months. Detailed information on the project can be found in the project TWiki http://cds.u-strasbg.fr/twikiAIDA/bin/view/EuroVOAIDA/WebHome. The Euro-VO project, in the framework of AIDA (Astronomical Infrastructure for Data Access), has launched a call for proposals for teams carrying out archival research or projects that could benefit from the Virtual Observatory concept. Successful applicants will receive support from EURO-VO astronomers in using the VO facilities and software to complete their projects. No direct funding is awarded in this programme, but support for travel to VO centres may be available if justified by the project. More details can be found at http://www.euro-vo.org/pub/fc/AIDA_call_2008.html. The registration period for the Euro-VO Workshop on "How to Publish Data in the VO", to be held at ESO June 23 - 27, is now open. The workshop is geared towards data centres and large projects to enable them to acquire the knowledge and experience necessary to publish catalogues, data products and other resources to the Virtual Observatory. More details can be found at http://www.euro-vo.org/dcaworkshop2008/France VOSince no France-VO report was posted on TM26 web page, this report summarizes the activities since the Exec face-to-face meeting held in Cambridge in September 2007 (FM25). The annual meeting of France-VO was held in Paris on 26-27 November 2007, with ~60 participants. Most French Observatories were represented. The lively presentations (mostly in French) and discussions showed the variety of VO-compliant services in development or at maturity, of technical programs (interoperability standards, workflows) which are presently under way in France, and some examples of science usages. Two topical meetings have also been organised under F-VO auspices:
GAVOHVOJapan-VOWe have successfully implemented the JVO portal system since 2008 March. Visit at http://jvo.nao.ac.jp/portal/. Anyone can access and dowload the observed data from more than 1,300 site in the world. More than 1 TBytes of data have already downloaded. We implemented a prototype for a workflow builder system based on the Taverna in order to easily construct data query and data analysis processes on a graphical user interface. Similar system has also been built in the UK, and we plan to compare our systems toward better, common system. Some project members were invited to give talks on the virtual observatory in several international meetings. It should be noted that the Core-to-Core program members published 104 academic papers, incuding 8 invited talks. We were informed that the Core-to-Core program of the JSPS will continue its support to the JVO for the fiscal year 2008 (April 2008 to March 2009). | ||||||||

VObs.itThe local arrangements for the May 08 Interop meeting in Trieste (May 18th to 23rd at the “Stazione Marittima” congress centre) are being completed. Info are available on the IVOA wiki (http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/InterOpMay2008) and on the local Web site dedicated to the meeting (http://www.si.inaf.it/ivoa_interop_2008/). Most of the logistics have been settled, an upgrade to the wi-fi provided by the congress centre is being set up. The company providing the booking for participants has proven to be not completely adequate: potential participants are encouraged to register as soon as possible. VObs.it has been funded by INAF for 2008, even though at an unsatisfactory level: there are funds to cover the May 08 Interop meeting, for travel and for two contracts related to VO activities (in Milan and in Teramo). Additional resources are received through the EU-funded projects (VO-Tech and VO-DCA). A proposal was prepared to build an integrated e-infrastructure for astrophysics (centered on VObs.it and computing resources) as part of a roadmap for scientific infrastructures to be submitted to the national Ministry of Research (MIUR). The proposal was not supported by INAF and did not reach MIUR. IA2 continues its collaboration with Heidelberg and Tucson to build a VO-compliant LBT-wide archive; a position for this work is being filled. Work is continuing within the EU-funded VO-Tech and VO-DCA projects. Two workshops, on Theory in the VO and on Grid and the VO, were co-organised by INAF/VObs.it and MPE/GAVO in the framework of the VO-DCA project, and held back-to-back in Garching during the week from April 7th to 11th (http://www.si.inaf.it/eurovow2008/index.htm). The meetings were well attended (over 70 participants) and successful, judging by the interest evidenced in the discussions.VO-IndiaReports from WGs & IGs(follows order as at http://www.ivoa.net/forum/)Applications WGSAMP - Simple Applications Messaging Protocol is in a period of intense discussion within the lead authors of the specification. A draft document is expected to be posted for wider discussion in preparation for the SAMP sessions in Trieste. A program of presentations of applications/tools/services is being prepared for the Trieste meeting. These presentations are intended to show and discuss implentations of VO standards. Discussion on how to better communicate the capabilities of VO applications to the astronomy community is also being planned.Data Access Layer WGThe DAL WG is actively involved the following areas:
Interaction with Registry Working GroupWe are especially interested in the Registry WG schema for Service Registration and the various Resource schemata as they present opportunities for DAL services to exploit.Interaction with Grid and Web Services Working GroupVOSI is of particular importance to DAL services, especially Capabilities and Availability. By their nature, DAL services typically need monitoring by systems administrators, so the work on Availability will be most relevant.Data Models WG (MireilleLouys)From the last Interop in september 2007, the DM working group was involved in the following :
Interaction with the Theory IG :
Models in action :
Grid and Web Services Working Group (MatthewGraham)The main activity for the GWS working group over the past few months has been VOSpace 1.1. A working draft of the specification, WSDL and schema was released on 16 January 2008. Reference implementations have been/are under development at Caltech, UCSD, JHU, Astrogrid and CDS. At least one of these (UCSD) also interfaces with the iRODS software from SDSC. There has also been work on the VOSpace usage document (Harrison, Morris) which describes the core metadata terms that we will be registering. Members of the WG have been looking at security issues, including delegation (Rixon, Graham), particularly with a view to a more RESTful approach; and authorisation (Graham). There has also been work on VOSI (Rixon) and CEA/UWS (Harrison).Registry WGOur primary effort has been in effecting the transition to the v1.0 standard for Registry Interfaces. We set a date of 21 April as the official start of v1.0 harvesting by which all nearly-ready registries should be ready by; all of those registries are now up and registered with the Registry of Registries (see http://rofr.ivoa.net/ for a list). Not included in this first round of compliant registries is the ESAC registry which we knew would require approx. 1 month of additional work. When this registry is ready, integration via the RofR should be transparent. The start of v1.0 registry harvesting this week will allow us several weeks of experience harvesting the new records and to uncover any remaining problems that might be discussed at Trieste. We note that AstroGrid, with its recent product release, has been operating their registries at the v1.0 standard for some time now. Prior to this week, they have used kept a cache of v1.0 records that they converted themselves from the old format records from the registries that were not ready yet. The transition should be seemless. The authors of the Outreach Metadata proposal, previously issued as an IVOA Note (http://www.ivoa.net/Documents/latest/AOIMetadata.html), have developed a revised version and have been actively engaging the outreach community for comments. This new version is currently be reformatted into a Working Draft. Once submitted to me, I will release it to the document repository, and develop a twiki discussion page. Their efforts have not gone unnoticed among alert IVOA people, and there is growing interest in this document (from Semantics and DM). The authors would like to encourage the development of prototypes and path-finder applications using this document. After a 6-month development period along with general discussion, we expect to hold a Registry WG session at the Baltimore IVOA meeting to discuss in detail the future of this document in the IVOA. Now that the long-delayed upgrade effort is (nearly) behind us, we are interested in moving remaining documents through the process, and begin considering advanced discovery and harvesting techniques. An important leading issue is the mechanism for harvesting detail metadata about services from the services themselves.Semantics/UCD WGVocabularies: A WD v1.0 on Vocabularies in the Virtual Observatory has been published recently (March 20, 2008).

Similar system has also been built in the UK, and we plan to compare our systems toward better, common system. Some project members were invited to give talks on the virtual observatory in several international meetings. It should be noted that the Core-to-Core program members published 104 academic papers, incuding 8 invited talks. We were informed that the Core-to-Core program of the JSPS will continue its support to the JVO for the fiscal year 2008 (April 2008 to March 2009).Korean VONVORVOSVOVObs.itThe local arrangements for the May 08 Interop meeting in Trieste (May 18th to 23rd at the “Stazione Marittima” congress centre) are being completed. Info are available on the IVOA wiki (http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/InterOpMay2008) and on the local Web site dedicated to the meeting (http://www.si.inaf.it/ivoa_interop_2008/). Most of the logistics have been settled, an upgrade to the wi-fi provided by the congress centre is being set up. The company providing the booking for participants has proven to be not completely adequate: potential participants are encouraged to register as soon as possible. VObs.it has been funded by INAF for 2008, even though at an unsatisfactory level: there are funds to cover the May 08 Interop meeting, for travel and for two contracts related to VO activities (in Milan and in Teramo). Additional resources are received through the EU-funded projects (VO-Tech and VO-DCA). A proposal was prepared to build an integrated e-infrastructure for astrophysics (centered on VObs.it and computing resources) as part of a roadmap for scientific infrastructures to be submitted to the national Ministry of Research (MIUR). The proposal was not supported by INAF and did not reach MIUR. IA2 continues its collaboration with Heidelberg and Tucson to build a VO-compliant LBT-wide archive; a position for this work is being filled. Work is continuing within the EU-funded VO-Tech and VO-DCA projects. Two workshops, on Theory in the VO and on Grid and the VO, were co-organised by INAF/VObs.it and MPE/GAVO in the framework of the VO-DCA project, and held back-to-back in Garching during the week from April 7th to 11th (http://www.si.inaf.it/eurovow2008/index.htm). The meetings were well attended (over 70 participants) and successful, judging by the interest evidenced in the discussions.VO-IndiaReports from WGs & IGs(follows order as at http://www.ivoa.net/forum/)Applications WGSAMP - Simple Applications Messaging Protocol is in a period of intense discussion within the lead authors of the specification.

Interaction with the Theory IG :
Models in action :
Grid and Web Services Working Group (MatthewGraham)The main activity for the GWS working group over the past few months has been VOSpace 1.1. A working draft of the specification, WSDL and schema was released on 16 January 2008. Reference implementations have been/are under development at Caltech, UCSD, JHU, Astrogrid and CDS. At least one of these (UCSD) also interfaces with the iRODS software from SDSC. There has also been work on the VOSpace usage document (Harrison, Morris) which describes the core metadata terms that we will be registering. Members of the WG have been looking at security issues, including delegation (Rixon, Graham), particularly with a view to a more RESTful approach; and authorisation (Graham). There has also been work on VOSI (Rixon) and CEA/UWS (Harrison).Registry WGOur primary effort has been in effecting the transition to the v1.0 standard for Registry Interfaces. We set a date of 21 April as the official start of v1.0 harvesting by which all nearly-ready registries should be ready by; all of those registries are now up and registered with the Registry of Registries (see http://rofr.ivoa.net/ for a list). Not included in this first round of compliant registries is the ESAC registry which we knew would require approx. 1 month of additional work. When this registry is ready, integration via the RofR should be transparent. The start of v1.0 registry harvesting this week will allow us several weeks of experience harvesting the new records and to uncover any remaining problems that might be discussed at Trieste. We note that AstroGrid, with its recent product release, has been operating their registries at the v1.0 standard for some time now. Prior to this week, they have used kept a cache of v1.0 records that they converted themselves from the old format records from the registries that were not ready yet. The transition should be seemless. The authors of the Outreach Metadata proposal, previously issued as an IVOA Note (http://www.ivoa.net/Documents/latest/AOIMetadata.html), have developed a revised version and have been actively engaging the outreach community for comments. This new version is currently be reformatted into a Working Draft. Once submitted to me, I will release it to the document repository, and develop a twiki discussion page. Their efforts have not gone unnoticed among alert IVOA people, and there is growing interest in this document (from Semantics and DM). The authors would like to encourage the development of prototypes and path-finder applications using this document. After a 6-month development period along with general discussion, we expect to hold a Registry WG session at the Baltimore IVOA meeting to discuss in detail the future of this document in the IVOA. Now that the long-delayed upgrade effort is (nearly) behind us, we are interested in moving remaining documents through the process, and begin considering advanced discovery and harvesting techniques. An important leading issue is the mechanism for harvesting detail metadata about services from the services themselves.Semantics/UCD WGVocabularies: A WD v1.0 on Vocabularies in the Virtual Observatory has been published recently (March 20, 2008). The WD is the result of a lively discussion, and it seems ready to move on to PR status in May. Cross-matching between vocabularies and use cases are the current open issues, and they will be debated in the coming InterOpMay2008.VOEventVOQL WGVOTable WGAstro-RG IG

SimDB has had lots of activity, visible for now on http://volute.googlecode.com/svn/trunk/projects/theory/snapdm/. It is ready for promotion to "standardisation" process, likely in DM WG. An IVOA Note detailing the proposed project and describing its current status will be ready for Trieste, where this will be discussed further. It might be interesting for the exec to discuss the process of how projects get turned into a standardisation project and who should be responsible. In particular the SimDB project has relations to other WGs: Registry, ADQL, DAL(TAP) Semantics. It suggests a structure where it is possible that small groups ("tiger teams") are created for standards development projects, that are not within the scope of a single WG. Such a group could act as a temporary WG and be made responsible for the whole process up to and including RFC of that project. SimDAP is being restarted with Claudio Gheller and Rick Wagner as main drivers and we hope it to be ready to be moved up to standardisation status-- NicholasWalton - 14 Jan 2008 <--

Reports from the ProjectsArVOAstroGridWe announced (1 Apr 2008) our release of the AstroGrid Desktop Suite : get it from http://www.astrogrid.org This was time to coincide with the UK National Astronomy meeting in Belfast. After various prototypes over several years, this is the first release of a complete set of software and working services. From the user's point of view we released three applications that run on the desktop - VODesktop; Topcat; and AstroGrid Python - and provided links to other Euro-VO tools that interoperate seamlessly - Aladin, VOSpec, SPLAT-VO. We also link to other VO tools - NVO services, VOPlot, etc. In the background we are operating a number of services - Registry, VOSpace, and Community - in several sites - and we have used our own DSA component to help UK data centres establish working data services. Of course VODesktop also provides access to the thousands of services worldwideAustralia-VOChina-VO | ||||||||

Added: | ||||||||
> > | Currently, there are 4 topics from our group. The first one is VO-DAS, which will be released to the community in June with support of several big datasets including SDSS DR6 (BestDR6 and SegueDR6), TwoMASS and GSC 2.2. The second one is a MatLab toolkit named AstroBox. We completed a PLASTIC module for MatLab so that it can work together with other VO tools. We plan to collect popular statistic and data mining algorithms into the AstroBox. So, astronomers can use it easily on MatLab platform. The third one is LAMOST archive system. It is a long-term but core task for the China-VO. And the forth work is development of a new version of FitHAS, the small FITS file DB importer. | |||||||
CVOEuro-VOThe EuroVO-DCA project has performed a census of astronomical data centres in European countries. Information about the census objectives and the census questionnaire can be found here. More than 65 data centres in a total of 14 different countries have answered. Two workshops about 'Theory in the VO' and 'Grid and the VO' were organised in the framework of the EuroVO-DCA project in MPE, Garching, by GAVO and and VObs.it (Trieste) respectively, with several participants from other VO projects. They led to interesting discussions, which will in particular be very useful in the definition of the SNAP protocol and for the Astro-RG Interest Group. The Euro-VO Astronomical Infrastructure for Data Access (EuroVO-AIDA) project started on February 1st for a duration of 30 months. Detailed information on the project can be found in the project TWiki http://cds.u-strasbg.fr/twikiAIDA/bin/view/EuroVOAIDA/WebHome. The Euro-VO project, in the framework of AIDA (Astronomical Infrastructure for Data Access), has launched a call for proposals for teams carrying out archival research or projects that could benefit from the Virtual Observatory concept. Successful applicants will receive support from EURO-VO astronomers in using the VO facilities and software to complete their projects. No direct funding is awarded in this programme, but support for travel to VO centres may be available if justified by the project. More details can be found at http://www.euro-vo.org/pub/fc/AIDA_call_2008.html. The registration period for the Euro-VO Workshop on "How to Publish Data in the VO", to be held at ESO June 23 - 27, is now open. The workshop is geared towards data centres and large projects to enable them to acquire the knowledge and experience necessary to publish catalogues, data products and other resources to the Virtual Observatory. More details can be found at http://www.euro-vo.org/dcaworkshop2008/France VOSince no France-VO report was posted on TM26 web page, this report summarizes the activities since the Exec face-to-face meeting held in Cambridge in September 2007 (FM25). The annual meeting of France-VO was held in Paris on 26-27 November 2007, with ~60 participants. Most French Observatories were represented. The lively presentations (mostly in French) and discussions showed the variety of VO-compliant services in development or at maturity, of technical programs (interoperability standards, workflows) which are presently under way in France, and some examples of science usages. Two topical meetings have also been organised under F-VO auspices:

In particular the SimDB project has relations to other WGs: Registry, ADQL, DAL(TAP) Semantics. It suggests a structure where it is possible that small groups ("tiger teams") are created for standards development projects, that are not within the scope of a single WG. Such a group could act as a temporary WG and be made responsible for the whole process up to and including RFC of that project.

Reports from the ProjectsArVOAstroGridWe announced (1 Apr 2008) our release of the AstroGrid Desktop Suite : get it from http://www.astrogrid.org This was time to coincide with the UK National Astronomy meeting in Belfast. After various prototypes over several years, this is the first release of a complete set of software and working services. From the user's point of view we released three applications that run on the desktop - VODesktop; Topcat; and AstroGrid Python - and provided links to other Euro-VO tools that interoperate seamlessly - Aladin, VOSpec, SPLAT-VO. We also link to other VO tools - NVO services, VOPlot, etc. In the background we are operating a number of services - Registry, VOSpace, and Community - in several sites - and we have used our own DSA component to help UK data centres establish working data services. Of course VODesktop also provides access to the thousands of services worldwideAustralia-VOChina-VOCVOEuro-VOThe EuroVO-DCA project has performed a census of astronomical data centres in European countries. Information about the census objectives and the census questionnaire can be found here. More than 65 data centres in a total of 14 different countries have answered. Two workshops about 'Theory in the VO' and 'Grid and the VO' were organised in the framework of the EuroVO-DCA project in MPE, Garching, by GAVO and and VObs.it (Trieste) respectively, with several participants from other VO projects. They led to interesting discussions, which will in particular be very useful in the definition of the SNAP protocol and for the Astro-RG Interest Group. The Euro-VO Astronomical Infrastructure for Data Access (EuroVO-AIDA) project started on February 1st for a duration of 30 months. Detailed information on the project can be found in the project TWiki http://cds.u-strasbg.fr/twikiAIDA/bin/view/EuroVOAIDA/WebHome. The Euro-VO project, in the framework of AIDA (Astronomical Infrastructure for Data Access), has launched a call for proposals for teams carrying out archival research or projects that could benefit from the Virtual Observatory concept. Successful applicants will receive support from EURO-VO astronomers in using the VO facilities and software to complete their projects. No direct funding is awarded in this programme, but support for travel to VO centres may be available if justified by the project. More details can be found at http://www.euro-vo.org/pub/fc/AIDA_call_2008.html. The registration period for the Euro-VO Workshop on "How to Publish Data in the VO", to be held at ESO June 23 - 27, is now open. The workshop is geared towards data centres and large projects to enable them to acquire the knowledge and experience necessary to publish catalogues, data products and other resources to the Virtual Observatory. More details can be found at http://www.euro-vo.org/dcaworkshop2008/France VOSince no France-VO report was posted on TM26 web page, this report summarizes the activities since the Exec face-to-face meeting held in Cambridge in September 2007 (FM25). The annual meeting of France-VO was held in Paris on 26-27 November 2007, with ~60 participants. Most French Observatories were represented. The lively presentations (mostly in French) and discussions showed the variety of VO-compliant services in development or at maturity, of technical programs (interoperability standards, workflows) which are presently under way in France, and some examples of science usages. Two topical meetings have also been organised under F-VO auspices:
GAVOHVOJapan-VOWe have successfully implemented the JVO portal system since 2008 March. Visit at http://jvo.nao.ac.jp/portal/. Anyone can access and dowload the observed data from more than 1,300 site in the world. More than 1 TBytes of data have already downloaded. We implemented a prototype for a workflow builder system based on the Taverna in order to easily construct data query and data analysis processes on a graphical user interface. Similar system has also been built in the UK, and we plan to compare our systems toward better, common system. Some project members were invited to give talks on the virtual observatory in several international meetings. It should be noted that the Core-to-Core program members published 104 academic papers, incuding 8 invited talks. We were informed that the Core-to-Core program of the JSPS will continue its support to the JVO for the fiscal year 2008 (April 2008 to March 2009).Korean VONVORVOSVOVObs.itThe local arrangements for the May 08 Interop meeting in Trieste (May 18th to 23rd at the “Stazione Marittima” congress centre) are being completed. Info are available on the IVOA wiki (http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/InterOpMay2008) and on the local Web site dedicated to the meeting (http://www.si.inaf.it/ivoa_interop_2008/). Most of the logistics have been settled, an upgrade to the wi-fi provided by the congress centre is being set up. The company providing the booking for participants has proven to be not completely adequate: potential participants are encouraged to register as soon as possible. VObs.it has been funded by INAF for 2008, even though at an unsatisfactory level: there are funds to cover the May 08 Interop meeting, for travel and for two contracts related to VO activities (in Milan and in Teramo). Additional resources are received through the EU-funded projects (VO-Tech and VO-DCA). A proposal was prepared to build an integrated e-infrastructure for astrophysics (centered on VObs.it and computing resources) as part of a roadmap for scientific infrastructures to be submitted to the national Ministry of Research (MIUR). The proposal was not supported by INAF and did not reach MIUR. IA2 continues its collaboration with Heidelberg and Tucson to build a VO-compliant LBT-wide archive; a position for this work is being filled. Work is continuing within the EU-funded VO-Tech and VO-DCA projects. Two workshops, on Theory in the VO and on Grid and the VO, were co-organised by INAF/VObs.it and MPE/GAVO in the framework of the VO-DCA project, and held back-to-back in Garching during the week from April 7th to 11th (http://www.si.inaf.it/eurovow2008/index.htm). The meetings were well attended (over 70 participants) and successful, judging by the interest evidenced in the discussions.VO-IndiaReports from WGs & IGs(follows order as at http://www.ivoa.net/forum/)Applications WG | ||||||||

Data Access Layer WGThe DAL WG is actively involved the following areas:
Interaction with Registry Working GroupWe are especially interested in the Registry WG schema for Service Registration and the various Resource schemata as they present opportunities for DAL services to exploit.Interaction with Grid and Web Services Working GroupVOSI is of particular importance to DAL services, especially Capabilities and Availability. By their nature, DAL services typically need monitoring by systems administrators, so the work on Availability will be most relevant.Data Models WG (MireilleLouys)From the last Interop in september 2007, the DM working group was involved in the following :

A working draft of the specification, WSDL and schema was released on 16 January 2008. Reference implementations have been/are under development at Caltech, UCSD, JHU, Astrogrid and CDS. At least one of these (UCSD) also interfaces with the iRODS software from SDSC. There has also been work on the VOSpace usage document (Harrison, Morris) which describes the core metadata terms that we will be registering. Members of the WG have been looking at security issues, including delegation (Rixon, Graham), particularly with a view to a more RESTful approach; and authorisation (Graham). There has also been work on VOSI (Rixon) and CEA/UWS (Harrison).Registry WGSemantics/UCD WGVocabularies: A WD v1.0 on Vocabularies in the Virtual Observatory has been published recently (March 20, 2008). The WD is the result of a lively discussion, and it seems ready to move on to PR status in May.

The registration period for the Euro-VO Workshop on "How to Publish
Data in the VO", to be held at ESO June 23 - 27, is now open. The workshop is geared towards data centres and large projects to enable
them to acquire the knowledge and experience necessary to publish
catalogues, data products and other resources to the Virtual Observatory. More details can be found at http://www.euro-vo.org/dcaworkshop2008/
France VOSince no France-VO report was posted on TM26 web page, this report summarizes the activities since the Exec face-to-face meeting held in Cambridge in September 2007 (FM25). The annual meeting of France-VO was held in Paris on 26-27 November 2007, with ~60 participants. Most French Observatories were represented. The lively presentations (mostly in French) and discussions showed the variety of VO-compliant services in development or at maturity, of technical programs (interoperability standards, workflows) which are presently under way in France, and some examples of science usages. Two topical meetings have also been organised under F-VO auspices:
GAVOHVOJapan-VOWe have successfully implemented the JVO portal system since 2008 March. Visit at http://jvo.nao.ac.jp/portal/. Anyone can access and dowload the observed data from more than 1,300 site in the world. More than 1 TBytes of data have already downloaded. We implemented a prototype for a workflow builder system based on the Taverna in order to easily construct data query and data analysis processes on a graphical user interface. Similar system has also been built in the UK, and we plan to compare our systems toward better, common system. Some project members were invited to give talks on the virtual observatory in several international meetings. It should be noted that the Core-to-Core program members published 104 academic papers, incuding 8 invited talks. We were informed that the Core-to-Core program of the JSPS will continue its support to the JVO for the fiscal year 2008 (April 2008 to March 2009).Korean VONVORVOSVOVObs.itThe local arrangements for the May 08 Interop meeting in Trieste (May 18th to 23rd at the “Stazione Marittima” congress centre) are being completed.

Most of the logistics have been settled, an upgrade to the wi-fi provided by the congress centre is being set up. The company providing the booking for participants has proven to be not completely adequate: potential participants are encouraged to register as soon as possible. VObs.it has been funded by INAF for 2008, even though at an unsatisfactory level: there are funds to cover the May 08 Interop meeting, for travel and for two contracts related to VO activities (in Milan and in Teramo). Additional resources are received through the EU-funded projects (VO-Tech and VO-DCA). A proposal was prepared to build an integrated e-infrastructure for astrophysics (centered on VObs.it and computing resources) as part of a roadmap for scientific infrastructures to be submitted to the national Ministry of Research (MIUR).

Reports from the ProjectsArVOAstroGridWe announced (1 Apr 2008) our release of the AstroGrid Desktop Suite : get it from http://www.astrogrid.org This was time to coincide with the UK National Astronomy meeting in Belfast. After various prototypes over several years, this is the first release of a complete set of software and working services. From the user's point of view we released three applications that run on the desktop - VODesktop; Topcat; and AstroGrid Python - and provided links to other Euro-VO tools that interoperate seamlessly - Aladin, VOSpec, SPLAT-VO. We also link to other VO tools - NVO services, VOPlot, etc. In the background we are operating a number of services - Registry, VOSpace, and Community - in several sites - and we have used our own DSA component to help UK data centres establish working data services. Of course VODesktop also provides access to the thousands of services worldwideAustralia-VOChina-VOCVOEuro-VOThe Euro-VO project, in the framework of AIDA (Astronomical Infrastructure for Data Access), has launched a call for proposals for teams carrying out archival research or projects that could benefit from the Virtual Observatory concept.

Info are available on the IVOA wiki (http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/InterOpMay2008) and on the local Web site dedicated to the meeting (http://www.si.inaf.it/ivoa_interop_2008/). Most of the logistics have been settled, an upgrade to the wi-fi provided by the congress centre is being set up. The company providing the booking for participants has proven to be not completely adequate: potential participants are encouraged to register as soon as possible. VObs.it has been funded by INAF for 2008, even though at an unsatisfactory level: there are funds to cover the May 08 Interop meeting, for travel and for two contracts related to VO activities (in Milan and in Teramo). Additional resources are received through the EU-funded projects (VO-Tech and VO-DCA). A proposal was prepared to build an integrated e-infrastructure for astrophysics (centered on VObs.it and computing resources) as part of a roadmap for scientific infrastructures to be submitted to the national Ministry of Research (MIUR). The proposal was not supported by INAF and did not reach MIUR. IA2 continues its collaboration with Heidelberg and Tucson to build a VO-compliant LBT-wide archive; a position for this work is being filled. Work is continuing within the EU-funded VO-Tech and VO-DCA projects. Two workshops, on Theory in the VO and on Grid and the VO, were co-organised by INAF/VObs.it and MPE/GAVO in the framework of the VO-DCA project, and held back-to-back in Garching during the week from April 7th to 11th (http://www.si.inaf.it/eurovow2008/index.htm).

Reports from the ProjectsArVOAstroGridWe announced (1 Apr 2008) our release of the AstroGrid Desktop Suite : get it from http://www.astrogrid.org This was time to coincide with the UK National Astronomy meeting in Belfast. After various prototypes over several years, this is the first release of a complete set of software and working services. From the user's point of view we released three applications that run on the desktop - VODesktop; Topcat; and AstroGrid Python - and provided links to other Euro-VO tools that interoperate seamlessly - Aladin, VOSpec, SPLAT-VO. We also link to other VO tools - NVO services, VOPlot, etc. In the background we are operating a number of services - Registry, VOSpace, and Community - in several sites - and we have used our own DSA component to help UK data centres establish working data services. Of course VODesktop also provides access to the thousands of services worldwideAustralia-VOChina-VOCVOEuro-VOFrance VOSince no France-VO report was posted on TM26 web page, this report summarizes the activities since the Exec face-to-face meeting held in Cambridge in September 2007 (FM25). The annual meeting of France-VO was held in Paris on 26-27 November 2007, with ~60 participants. Most French Observatories were represented. The lively presentations (mostly in French) and discussions showed the variety of VO-compliant services in development or at maturity, of technical programs (interoperability standards, workflows) which are presently under way in France, and some examples of science usages. Two topical meetings have also been organised under F-VO auspices:

< < | F-VO is also active at European level, in particular to the Coordination activities organised by the EuroVO-DCA project: active participation to the Theory and Grid Workshops organised on 7-11 April 2008 at MPE (Garching) respectively by GAVO and VObs.it and to the census of European data centres. CDS organised in Strasbourg the kick-off meeting of the EuroVO-AIDA project (17 March 2008), and the bi-annual meeting of the VO-TECH project, which was also the first Euro-VO Technology Forum of the EuroVO-AIDA project (17-20 March). | |||||||
> > | The Action Spécifique Observatoires Virtuels France (ASOV, which is F-VO) has decided that the subject is now mature enough to organise one single AO in 2008 (instead of 2 previously). This AO was opened in December 2007 with a closing date on January 2008. The limited amount of money available will be used to support travel to Interops and to F-VO Working Group meetings, and some collaboration meetings. ASOV Scientific Council also evaluates proposed participation to Euro-VO Workshops (which are then supported on European funds managed by CNRS). | |||||||

> > | The main activity for the GWS working group over the past few months has been VOSpace 1.1. A working draft of the specification, WSDL and schema was released on 16 January 2008. Reference implementations have been/are under development at Caltech, UCSD, JHU, Astrogrid and CDS. At least one of these (UCSD) also interfaces with the iRODS software from SDSC. Members of the WG have been looking at security issues, including delegation (Rixon, Graham), particularly with a view to a more RESTful approach; and authorisation (Graham). There has also been work on VOSI (Rixon) and CEA/UWS (Harrison). | |||||||
Registry WGSemantics/UCD WGVocabularies: A WD v1.0 on Vocabularies in the Virtual Observatory has been published recently (March 20, 2008). The WD is the result of a lively discussion, and it seems ready to move on to PR status in May. Cross-matching between vocabularies and use cases are the current open issues, and they will be debated in the coming InterOpMay2008.VOEventVOQL WGVOTable WGAstro-RG IG

Reports from the ProjectsArVOAstroGridWe announced (1 Apr 2008) our release of the AstroGrid Desktop Suite : get it from http://www.astrogrid.org This was time to coincide with the UK National Astronomy meeting in Belfast. After various prototypes over several years, this is the first release of a complete set of software and working services. From the user's point of view we released three applications that run on the desktop - VODesktop; Topcat; and AstroGrid Python - and provided links to other Euro-VO tools that interoperate seamlessly - Aladin, VOSpec, SPLAT-VO. We also link to other VO tools - NVO services, VOPlot, etc. In the background we are operating a number of services - Registry, VOSpace, and Community - in several sites - and we have used our own DSA component to help UK data centres establish working data services. Of course VODesktop also provides access to the thousands of services worldwideAustralia-VOChina-VOCVOEuro-VOFrance VOGAVOHVOJapan-VOKorean VONVORVOSVOVObs.itVO-IndiaReports from WGs & IGs(follows order as at http://www.ivoa.net/forum/)Applications WGData Access Layer WG | ||||||||
