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
    • SimDAP
    • S3
  • ...
