([[IVOA.IVOATheorySimDB][back to main]])<br/>
This page is devoted to describing the [[IVOA.IVOATheorySimDB][SimDB]] data model (!SimDB/DM from now on).

---++ Current model
As described [[IVOA.IVOATheorySimDB][here]] all development can be followed on Volute.
Particularly relevant for the discussion on this page is the data model in [[http://volute.googlecode.com/svn/trunk/projects/theory/snapdm/specification/uml/SimDB_DM.xml][uml/SimDB_DM.xml]].
The previous versions as well as later working versions can be found in the history of this file, as well as its direct predecessor  [[http://code.google.com/p/volute/source/browse/trunk/projects/theory/snapdm/input/SimDB_DM.xml?r=902][version r902]].
An image of the latest version of the model is reproduced at the bottom of this page.

---+ To be discussed
   * OK on approach?
      * modelling: analysis(conceptual)->logical->physical
      * TAP+XML+UTYPE serialisations derived from logical model
   * Identify main issues of model
      * sufficiently detailed resources?
      * characterisation, provenance etc (see [[IVOA.IVOATheorySimDBDM_CharProv][separate page]])
      * normalisation (problem for XML, little for TAP)
      * "queriability" (problem for TAP)
      * missing semantic vocabularies
      * quantities/units
   * Clean up
      * documentation in the UML
      * Description of model in Note
   * finalise the serialisation to UTYPEs
   * finalise the serialisation to TAP (see [[IVOA.IVOATheorySimDBTAP]])
   * finalise the serialisation to XML schema ((see [[IVOA.IVOATheorySimDBREST]])
   * reuse by other specs
      * !SimDAP
      * S3
   * ...
