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.

Applications WG

SAMP: At Nara a presentation was made of the "Web Profile", a hub interface suitable for browser-based SAMP clients, which cannot easily use SAMP in its existing form. This would enable web applications to participate in SAMP communications in the same way that desktop tools can. There was agreement that this should be pursued with a view to absorbing it into the SAMP standard, though some outstanding issues about security were noted.

A new Working Draft has just been released (WD-SAMP-1.3-20110512) incorporating the Web Profile. Implementations exist for most aspects of this document. We will discuss this draft at this meeting, and in particular we will attempt to reach agreement on the security issues. If this is successful, we hope to move towards Recommendation status for SAMP 1.3 in the second half of 2011.

Application Registration: We are in the early stages of dicussions of how VO users do discovery of applications and services, in the SAMP context in particular, but also more generally. E.g., we may want some kind of Apps store. This certainly involves the Registry group and may ultimately involve GWS as well.

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.

Theory IG

* 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.
