---++ *Update 2023-09-20*

These pages are quite out of date!

They will be updated and edited over the next couple of months with new activity from the Theory Interest Group. Stay tuned for more!
---++ *Ongoing activities*

Works done by the Theory I.G. are divided in three packages.
---+++ <span style="font-weight: normal;">Simulation Access Protocol</span>

Most efforts are now done on the definition of an access protocol to access theoretical data through the Virtual Observatory.

Some use cases relevant to theoretical spectra are already taken into account in the Simple Spectral Access Protocol.

SimDAL the access protocol for theoretical data, will cover more use cases.

Status:

   * SimDAL global architecture has been approved at ESAC 2014 InterOp
   * SimDAL architecture has been refined during the <a href="IvoaTheoryParis14" target="_self" title="2014 Paris Theory meeting"><strong><span class="WYSIWYG_COLOR" style="color: #ff7f50;"><span class="WYSIWYG_COLOR" style="color: #00008b;">Paris 2014 meeting</span></span></strong></a>
SimDAL roadmap to converge to a PR has been precised during the <a href="IvoaTheoryParis14" target="_self" title="2014 Paris Theory meeting">Paris 2014 meeting</a>.
---+++ <span style="font-weight: normal;">Simulation Data Model</span>

The Simulation Data Model 1.0 has been recommended by EXEC on May 3rd 2012.
   * The recommendation can be found <a href="http://www.ivoa.net/documents/SimDM/" target="_blank" title="SimDM recommendation">here</a>
   * The implementation note is <a href="http://www.ivoa.net/documents/Notes/ImplementationSimDM" target="_blank" title="SimDM implementation node">here</a>
Activities on this package are now dormant.
---+++ <span style="font-weight: normal;">SKOS vocabularies</span>

SKOS concepts are used in the Simulation Data Model to describe quantities and the algorithm in use in simulation. The development of these vocabularies (physical quantities, algorithms, input parameters, output parameters ...) is an ongoing process. Some of these vocabularies are accessible on <a href="http://votheory.obspm.fr/" target="_blank" title="Theory SKOS concepts">Theory SKOS concepts website</a>.

   * <span style="background-color: transparent;">Description: Concepts in this vocabulary are intended to be used to describe algorithms in SimDM classes. </span>
   * <span style="background-color: transparent;">Authors: Nicolas Moreau, Zakaria Meliani, Fabrice Roy, Franck Le Petit, David Languignon </span>
   * <span style="background-color: transparent;">The SKOS version has been produced by Nicolas Moreau</span>

---++ <span style="color: #630000; font-size: 19px; line-height: 1em;"> *Charter* </span>

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 [[http://www.ivoa.net/pub/papers/TheoryInTheVO.pdf][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 [[IVOA.FranckLePetit][Franck Le Petit]], vice-chair is [[IVOA.RickWagner][Rick Wagner]].

---++ *Project Pages*

---+++ Protocols to access simulations

In the following we refer these protocols generically as _Simulatuion Data Access Layer_ (<nolink>SimDAL</nolink>). Currentlly there are two types of <nolink>SimDAL</nolink> flavors (depending on its IVOA status)

   * _IVOA accepted protocols_:
      * [[http://ivoa.net/Documents/SimDM/20120503][Simulation Data Model 1.0]]
      * Access to theoretical data is included in SSAP protocol an refers to the acces of theoretical spectra. More details can be found in this page [[IVOATheoryTSAP][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:

---+++ [[TheorySemanticVocabulary][Semantics]]

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

General data model for describing simulations. The version 1.0 has been recommended on May 3rd 2012.

Most results of this effort can now be found in the [[http://volute.g-vo.org/svn/trunk/projects/theory/snapdm/specification][volute SVN repository]] on <noautolink>GoogleCode</nouatolink>, originally set up by Norman Gray.

All comments received during the various RFC periods for the version 1.0 can be found [[here][http://wiki.ivoa.net/twiki/bin/view/IVOA/IVOATheorySimDMspec]]

[[IVOATheorySimDMspec][SimDM/DM : all the documents for the specification during the preparation are there]] but please look at [[http://ivoa.net/Documents/SimDM/]] for the last and recommended version.
