BRAVO

BRAVO has established a partnership with the Brazilian part of the J-PAS consortium and will co-manage
the data (archival and publishing) of the T80-south telescope, being built in Chile. To be able to fund
new activities, BRAVO answered a call from FAPESP (Sao Paulo Research Foundation) for eScience projects.
During the project's design, BRAVO built new connections with computer scientists in two institutions
in Sao Paulo, who will collaborate in future BRAVO projects. This eScience project is particularly
critical given that the program which funded BRAVO activities in recent years (INCT-A) is coming to an
end, which caused a halt on any new activity (except for the co-organization of a workshop in June). The
selected projects to be funded by FAPESP will be announced in October. If our project is approved, this
will be BRAVO's main source of funding for the next 5 years.

VObs.it

As agreed within the Exec, there will be a split of responsibilities in the management of the IVOA Web pages and Document Repository. In the future VObs.it (and specifically the IA2 data centre located at INAF-OATS) will host the IVOA domain, mail & wiki. A technical contact point and a maintenance responsible have been identified. The procedures for the switch from VAO to VObs.it have been agreed between Caltech and INAF-OATS information system administrators and have been initialized. The ownership and the authoritative nameservers of the two domains ivoa.net and ivoa.info have already been transferred; technical details on the hand-over of all other involved IVOA services (www, wiki, ftp, etc.) are being exchanged between the two teams.

VObs.it is organizing the Spring 2015 Interoperability Meeting, which will be held in Sesto/Sexten (in the Dolomites), at the Haus Sexten Congress Hall hosted by the Sexten Center for Astrophysics (http://www.sexten-cfa.eu/ ). Meeting dates will be 15-19 June (to be confirmed). Two coaches will be organized to bring participants on 14 June from Venice airport to the Interop location and back on 19 June. For participants not being able to take advantage of this service (or not attending the full meeting), there is a shuttle service from the Venice and Treviso airports to the railway station in Toblach/Dobbiaco (12 km away from Sesto): this transfer may be booken on www.cortinaexpress.it; individual transportation can be arranged (200 Euro a one-way trip to the Venice and Treviso airports for max 8 people).

A note was prepared within the Interest Group in Education (Edu IG), concerning the creation and deployment of astrophysical resources dedicated to education within the standard VO framework ( http://wiki.ivoa.net/twiki/bin/view/IVOA/IvoaEducation ).

VAO

The VAO has focused its activities on executing the VAO Project Execution Plan (PEP) for the period May 1, 2013 and through September 30, 2014, approved on June 8, 2013. Briefly, the plan calls for completion of all deliverables already underway, continued monitoring of services, preparation to deliver VAO assets to the community and delivery of a protocol and data discovery and data access service for multi-dimensional data sets.

The VAO hosted the semi-annual interoperability workshop in Waikoloa, HI, consecutively with the annual ADASS conference, and has developed an agenda for the VAO close-out review, scheduled for July 10 and 11, 2014 in Pasadena, CA, and stakeholders in the project have been invited to attend. VAO management consulted with NASA archive staff to support their proposal to sustain the VAO infrastructure.

VAO staff has been active in the community: they have made presentations at conferences, and have participated on panel discussions and workshops. VAO staff holds leadership roles in the IVOA, and have contributed to the development of five IVOA standards. VAO personnel have also been active in the Research Data Alliance (RDA), an international initiative to foster data access and exchange throughout the research community.

The final versions of the Data Discovery tool, Iris (the Spectral Energy Distribution service) and the Cross-comparison service have been delivered. These releases offer new functionality for users and correct several defects that have been reported. The new releases include updated user documentation and video tutorials.

Repositories have been set up to host the VAO code base and documentation with Google’s free cloud-based services. The code repository has been populated with essentially all versions of software components delivered to date, and new components are transferred there each month as they are delivered. The documentation repository has been populated with user guides and tutorials, project reports, professional outreach materials, and a list of technical publications and presentations by team members.

The VAO has begun the transfer of IVOA communication assets (web site, wiki and mailing lists) to VOIndia and VOItaly. The VAO Program Manager is coordinating these efforts on behalf of the IVOA Executive Council.

VO science services were available 98% of the time, even with the shutdown of the federal government. The VAO validation services detected a dramatic decrease in validation statistics, which was attributed to changes in Vizier data services. The VAO informed Vizier staff and the problem was corrected. VO infrastructure requests remained steady during 2013 and early 2014, except for a surge in Registry queries in late 2103. Between March 30, 2013 and April 11, 2014, 327 tickets were filed with the JIRA ticket system and 245 were closed.

A major effort for the VAO is support for discovery of and access to multidimensional data sets (“data cubes’), identified as a key science initiative by the IVOA. The VAO has been providing leadership in this endeavor. A white paper delivered in May 2013 described the mechanisms and science drivers for serving data cubes, and led to the development of a prototype data access that served data from a range of projects. Concurrently, the VAO proposed modifications of existing standards and data models that were mandated by this service, and a successful demonstration at the Winter IVOA meeting led to agreement on the necessary requirements to support data cube. VAO staff is working with international partners to present mature versions of the Image Data Model, Simple Image Access Protocol v2, and DataLink at the Spring 2014 meeting.

The VAO established a partnership with the NRAO to support scalable access to the large datasets from ALMA and JVLA, and to support seamless access to their visualization toolkit, CASA. To date, the VAO has delivered an enhanced DALServer to provide access to data cubes, and NARO has integrated the VOClient tools into the CASA software.

The SciDrive data sharing and publication service has been made accessible to users for evaluation. It provides 100-TB storage with triple redundancy, and includes the Single Sign On service. Upgrades to the registry and data publishing tool are being readied for release.

A production release of the VOClient, which offers command line access to the VO, was deployed in January 2014, and two beta releases of the native Python package, PyVO, were released through the Astropy community-supported platform.
