Objectives achieved and even further !

Diversity of theoretical products (Session 1): many products accessible on-line

3D+Time: CADAC (Rick), CINECA (Claudio), StarFormat (Franck), GalMer (Igor) non-spatial: PDRDB (Franck), stellar isochrones/evolutionary tracks (Carlos, Miguel),

synthetic photometry (Carlos, Miguel), astrosismology models (Carlos, Miguel) many diverse science (and use) cases: cosmology, cluster of galaxies, star

formation, cloud collapse, stellar isochrones, photodissociation,… a very good sampling of the real world and real use of theoretical products

2010-May-19 H. Wozniak / Obs. Strasbourg / VO-France 5

Objectives achieved and even further !

SimDB/DM (Session DM+TIG): under DM WG auspices, finalization of the Simulation DM (part of the SimDB) we needed approx. 4 * 2hrs + 1 normal session = 9.5 hrs to freeze the DM agreement on SimulationDM to cover ALL theoretical products

One name (simulation), one root (Sim*), one SimDAL (Session 2) for every kind of theoretical product !

Actions and Roadmap

SimDB/DM (SimDM) action leaders: Mireille & Gerardaction players: Mireille, Gerard, Benjamin, Franck,

Miguel, Carlos, Rick, Claudio, Hervé, Laurent write the specification in IVOA document format with DM collaboration entrust SimDM to DM WG timeline :

specification finalization (DL: end of June) recommendation path during summer after DM WG review REC by EXEC in Nara (hopefully)

mapping of all theory services (SVO, CINECA, BaSTI) to SimDM action leaders: Miguel, Patrizia

action players: Miguel, Carlos, Patrizia, with Franck’s expertise

Actions and Roadmap

SimDB/Service action leaders: Gerardaction players: Gerard, Benjamin, Franck, Nicolas

experts (see Baltimore conclusions): Norman, Mireille, Keith, REGISTRY? need to query on a SimDB service two preliminary implementations rely on several others IVOA standards

semantics vocabulary TAP VOSI …

need to resume work on it by July

Actions and Roadmap

Semantics action leaders: Fabrice & Franckaction players: ALL

Astrophysical Objects: Ex: Galaxy, disk, bulk, Cloud, gas, jets, ... Physical quantities: Ex: Velocity, Temperature, Temperature of electrons, ... Physical processes Ex: Gravitation, MHD, hydrodynamics, Radiative transfer Algorithms Ex: Tree, SPH, Vlasov solver, Monte Carlo,…

Largest participation of people interested in Theory products required Expertise in different fields of (astro)physics is mandatory http://vocabularies.referata.com/wiki

Priorities :1. Finalize the Algorithm vocabulary (DL: next INTEROP)2. Develop the other vocabularies

1. Physical processes (subset of IVOAT + a few missing processes)2. Astrophysical object (Ontology of astronomical objects + a few other processes)3. Physical properties (UCDs + vocabulary)

Actions and Roadmap

SimDAL (including SimDAP and S3) action leaders: Claudio & Rick

action players: Claudio, Rick, Carlos, Miguel, Benjamin, Franck, Nicolas, Gerard

becomes very urgent ! SimDM is there (quite soon) testing facilities available need to work as soon as possible with DAL WG

2010-May-19 H. Wozniak / Obs. Strasbourg / VO-France 10

Roadmap

Roadmap Next INTEROP (7-13 Dec 2010 @ Nara, Japan) BEFORE :

1. SimDM: regular telecon on writing SimDM specification (Louys, Wozniak, Gheller, Cerviño, Lemson, Le Petit, Ooghe, Rodrigo Blanco, Wagner, Bourgès)

2. DM WG: start WG discussions in July3. resume work on SimDB and SimDAL : an intermediate meeting (2 days?)

1. when ? September (doodle pool to be done)2. what ? SimDB and SimDAL3. where ? Strasbourg (central wrt Bologna-Madrid-Munich-Paris) 4. who ?

Gheller, Wagner, Cerviño, Lemson, Le Petit, Ooghe, Rodrigo Blanco, Wozniak,…

At Nara INTEROP Top priorities : SimDAL (presentations in DAL sessions or common one?), SimDB,
