The Simulation Data Model TCG review is opened from Oct 20th for a month. Documents are there. Please comment here

Charter

During the IVOA executive meeting of Jan. 2004 in Garching, Germany, the IVOA Theory Interest Group was formed with the goal of ensuring that theoretical data and services are taken into account in the IVOA standards process. In a whitepaper published on the IVOA site issues specific to theory are discussed. The document also summarizes tasks that a possible theory working group should accomplish, listed here as a proposed charter for the group.

The IVOA Theory Interest Group will:

• Provide a forum for discussing theory specific issues in a VO context.
• Contribute to other IVOA working groups to ensure that theory specific requirements are included.
• Incorporate standard approaches defined in these groups when designing and implementing services on theoretical archives.
• Define standard services relevant for theoretical archives.
• Promote development of services for comparing theoretical results to observations and vice versa.
• Define relevant milestones and assign specific tasks to interested parties.

After Victoria May-2010 Interop, we refer as simulation to any kind of theoretical data/archive/result that can be used in the VO.

This Interest Group is chaired by Herve Wozniak, vice-chair is Franck LePetit.

Simulation Data Model

General data model for describing simulations.

SimDM/DM : all the documents for the specification in preparation are there

Most results of this effort can now be found in the volute SVN repository on GoogleCode, originally set up by Norman Gray.

The RFC period is opened from May 4th for a month. Please comment http://www.ivoa.net/cgi-bin/twiki/bin/view/IVOA/IVOATheorySimDMspec

Semantics

The Simulation Data Model largely relies on concepts. These concepts are organized in SKOS vocabularies following the Semantic Working Group recommendations. Semantic vocabulary needed to find/define different kinds of theoretical data

Protocols to access simulations

In the following we refer these protocols generically as Simulatuion Data Access Layer (SimDAL). Currentlly there are two types of SimDAL flavors (depending on its IVOA status)

• IVOA accepted protocols: Currently the only accepted protocol able to acces theoretical data is included in SSAP protocol an refers to the acces of theoretical spectra. More details can be found in this page TSAP (SSAP theory use case)

• TIG developments: Current developments try to converge to a possible common access protocol (that should include TSAP at the end). Current working protocols are:

SimDAP		C. Gheller and R.Wagner

Historical Follow-up

• Use cases (after Kyoto 2005 Interop)
• General requirements extracted from used cases (after Kyoto 2005 Interop)
• SNAP and why SNAP has been split up in SimDB and SimDAP (Jun 2008)

National contacts

Following the IVOA interoperability meeting in Cambridge, MA, USA May 2004, the various national VO's have assigned one or two contact persons for dealing with theory issues, representing the theory interest group to their community and vice versa, representing their community to the theory interest group. The following is the current list of these contact persons with their affiliation and e-mail addresses:

Use cases

During the interoperability meeting in Kyoto, 2005, it was decided that science use cases will be defined by a various members of the theory group. These were to be posted and used to extract requirements for the various IVOA working groups. A link to a page listing the submitted workpages can be accessed here.
