This page is devoted to describing the SimDB data model (SimDB/DM from now on).

 Current model 
As described here all development can be followed on Volute.
Particularly relevant for the discussion on this page is the data model in 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  version r902.

  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
  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
