1 May 18, 2007TIG, closing plenary Conclusions from theory IG sessions, Beijing 2007

2 May 18, 2007TIG, closing plenary 3 sessions SNAP data model –overview –validation (Patrizia Manzato) SNAP protocol (for Claudio Gheller) –discovery –query –registration –services Presentations –Nicolas Moreau: Dalia, interface for simulation codes –Vincenzo Costa: theory metadata database as SNAP prototype –Franck Le Petit: theory services in AstroGrid –GL: theory database –no other business

3 May 18, 2007TIG, closing plenary To do: SNAP DM Completion model. Issues: –characterisation, –semantic vocabularies –units Usage –serialisation to XML schema (for validation, registration, XQuery based discovery) –relational mapping (for ADQL based discovery) –serialisation to UTYPE list (for representation in VOTable, possible simple discovery) Validation –produce XML docs describing variety of simulations Patrizia Manzato, Jean-Paul Lefèvre, Tom Theuns/Joop Schaye, Peter Teuben, Rick Wagner, Klaus Dolag, GL, more? Propose to IVOA DM WG prototype/proof-of-concept(/Reference?) implementations

4 May 18, 2007TIG, closing plenary To do: SNAP protocol Discovery+query –investigate simple (HTTP GET) approach further –investigate (i.e. prototype) SNAP portal/archive approach (Italy, France?, US?, VOExplorere-like) –work with registry group on architecture (Ray Plante) SNAP services –Define some standard services+interface download cutout visualise... –Allow and promote (registered) custom services –Follow DAL/GWS on capabilities, staging, delivery etc Propose to DAL as Note following standard doc format, but with place holders.

5 May 18, 2007TIG, closing plenary To do: contact the community Validate approach to theory data centers –contact theory representatives to do so locally Validate approach towards potential users, both theorists and observers –contact theory representatives to do so locally

6 May 18, 2007TIG, closing plenary Requests to WGs DM: We need input on treatment of units and want to further discuss characterisation Semantics: We need input (or feedback) on standard vocabularies for –physical processes –astronomical objects –observables (UCDs) –numerical artefacts DAL/GWS: We need to hear how to deal with SNAP services in a standard manner. Registry: We need to further develop the way SNAP archive/portal will interact with registry. Applications?: Wed like a browser for real data models, ala VOExplorer. Action on theory group: use mailing lists

7 May 18, 2007TIG, closing plenary Dates, roadmap SNAP DM Note to DM WG –September 2007 (month before interop) SNAP protocol Note to DAL WG –Needs discussion with Claudio Gheller (who leads this effort) et al, in June. –Target September 2007 (month before interop) Proof of concept implementations: registration+discovery of simulations –Promised by Italy, France. Maybe also US, UK/Germany? –Will ask them when in June 2007 Outreach, gathering feedback –Mail to TIG reps, June 2007 –Results unpredictable, report by Cambridge interop

8 May 18, 2007TIG, closing plenary AOB Do we need a different name for SNAP? –not all numerical products covered –not simple –not Supernova/Acceleration Probe –Please send proposals to theory mailing list. Q: Any other standardisation efforts desired, e.g. theory spectra? No.
