Simulation data model

NOTE: pages on SNAP data model are being re-organised SNAP is oing to separate in 2 relatively independent parts: SimDB (Simulation Database) and SimDAP( Simulation Data Access Protocol). The products of these efforts, while in development, can be followed on a Google code SVN repository, originally set up by Norman ray for the Semantics WG. We use the following sub-set of this: http://volute.googlecode.com//svn/trunk/projects/theory/snapdm/. Until further notice the current Wiki pages will be updated only very occasionally.

This page shows the progress in the creation of an IVOA data model for simulations. It contains links to pages with UML models, XML Schema serialisations, and documentation them. On this page one also finds links to relevant references.

• UML diagrams
• XML Schema serialisations
• Online version of the documentation of the data model
• Discussions page. In the form of a FAQ we discuss various issues and describe reasons for particular resolutions to them that we have made.

Drafts for IVOA simulation data model (continuously updated)

UML2 diagrams have been created by (and can be read) using MagicDraw community edition v 12.1.

• Analysis model of the simulation domain. This model is not part of the specification and is only added here as background material. It is bascially an alternative, still wordy version of the Domain model for astronomy.
