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
- ...
