Reports from the Projects

AstroGrid

No significant update from last time. AstroGrid is no longer funded as an STFC line item, but the code, services and tools remain in use, and many members of the team continue to work on VO related EU or STFC funded projects (VOICE, VAMDC, Topcat) or undertaking VO duties as part of facility and data centre work (VISTA, ALMA, SDO, Gaia). We are exploring methods to formalise the currently loose sense of continuing consortium connections; this may continue the AstroGrid name, or may opt for a deliberate re-branding.

Data Models WG

• Photometry modeling :

WD-PhotDMv0.3 issued and discussed in the Working group. To discuss during this Interop: how to bring together complementary documents: PhotDMv0.3 , Spectrum1.2, and SED DM.

S. Derriere issued a new version for "Note on serializing photometric data measurements in VOTable" using the PhotDM concepts for source catalogs.

• SpectrumDM
• v1.1 :updates for alignment with SSA v1.1: done. Short RFC (15 days ) started on May 4.

• v1.2 : draft issued in January by Jonathan McDowell
  • expands Spectrum1.1
  • contains Photometry metadata re-used from the note on Photometry point and the photometric calibration defined in PhotDM
  • contains TimeSeries examples circulated on the DM list

• ObsCore DM v1.0

Proposed recommendation started 03rd of May and published on DAL/DM. Implementations going on at CADC, with lessons learned to be discussed at this interop.

• Characterisation DM v2.0 Working draft currently edited. This document expands previous version of CharDM and define support for:
  • polarised data,
  • Redshift axis
  • variability along the characterisation axes (level4)
  • composed data

• Utypes Note

Still pending- currently needed to publish new DM and their Utype list. Summary of current usage and definition rules at DM3 (M.Louys) and possibly discussion in splinter meetings.

• Simulation DM :

Proposed Recommendation issued on May 3 and currently discussed. Implementation Note to finalise.

* The RFC period for the Simulation Data Model (http://www.ivoa.net/cgi-bin/twiki/bin/viewauth/IVOA/SimRFC/PR-SimulationDataModel-v.1.00-20110428.pdf) has been opened on May 4th by DM Chair, after updates and modifications according to comments on the TIG and DM lists in March-April.

* Discussions on SimDAL, including the TAP implementation, and the SimDB proposal will be resumed at the next INTEROP. These are the main and urgent efforts for the future since SimDM is close to recommendation.
