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

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

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

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)

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

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,
