---++ Reports from the Projects

---+++ <nop>ArVO

Recently the Armenian VO received a new office in Byurakan. There are 6 persons working for ArVO: Areg Mickaelian (PI), Tigran Magakian (Project scientist), Lida Erastova, Lusine Sargsyan, Lilit Hovhannisyan, and Parandzem Sinamyan. Two more students are involved in the project as well. ArVO continued its development on the collaboration between its team based in the Byurakan Astrophysical Observatory (BAO) and the Institute of Problems of Informatics and Automation (IPIA) of the Armenian National Academy of Sciences. The IPIA has a powerful Armcluster computer, where a number of large scientific projects are being carried out. The IPIA allocates software experts for joint work with the Byurakan team members (all are astronomers). A 1TB disk space has been allocated on the ArmCluster for ArVO's activities. This will be used for a number of large astronomical catalogs, and the tasks that will run on the Armcluster will be cross-correlations between large catalogs (including the DFBS spectroscopic database), theoretical calculations, and modeling. 

The DFBS Roma web interface (DFBS portal) is almost finished. A.Mickaelian will visit Rome this December to finalize the tasks, and to start the low-dispersion spectra classification works. ArVO team member L.Sargsyan will have a 2 months stay in Rome for this work. It is planned that the users will have access to all 40,000,000 spectra and their suggested classification, which will allow to select objects of necessary types, make samples, study definite fields, etc.

The Digitization works of the Byurakan archive plates are being continued. The digitized Byurakan plates will make up the main part of the Armenian astronomical data centre. The establishment and utilization of the Virtual Observatories standards in Armenia is being continued, too.

----+++ Data Curation and Preservation IG
There are four large initiatives in the EU and the UK that are investigating preservation:
- CASPAR  (David Giaretta)
- PLANETS (Adam Farquhar, Hans Hofmann)
- DPE     (Seamus Ross)
- Digital Curation Centre (Chris Rusbridge)

The projects are investigating representation (CASPAR) - how to characterize the structure and information content of digital documents, and management policies (PLANETS) - how to enforce preservation policies such as the number of replicas and migration to new technology.  They are also constructing testbeds for the demonstration of preservation tools and services.

The related projects in the US include:
- NARA Transcontinental Persistent Archive
- NHPRC Persistent Archive Testbed
- Library of Congress NDIIPP
- Library of Congress DigArch
- DSpace
- Fedora

Each of these preservation projects is building upon data grid technology for the management of distributed shared collections.  The goal is to differentiate between management of distributed data and application of preservation processes that generate the required archival form.

SDSC is collaborating on development of open source software with these projects based on iRODS (integrated Rule-Oriented Data System).  The first release is scheduled in the next 1-2 weeks.  This new technology is intended to automate the application of management policies across distributed shared collections.

The IVOA needs to specify the management policies that are required for image archives, for data products used in publications, and for the processes that generate the data products (mosaics, image cutouts, simulation output).
