  Dear all,
    could you please point me to software / technologies helpful
  when looking for a standalone XForms data model implementation ?

  Since UI does not matter in this case the sought solution would
  just provide for dynamic persistent data storage supporting:

   - literal and computed values (like xforms:bind/@calculate)
   - constraint expressions on values (like xforms:bind/@constraint)
   - data selection via a path/query langauge (XPath or e.g. TreeHugger for RDF)
   - data model based on a XML info set (or RDF triple or quad model)

  I had a look at active databases, which would require to define the
  dependency graph explicitly using the underlying simple Event-
  Condition-Action pattern. The proposal of an "standards-based
  virtual machine" by Mark Birbeck seems to share the notion of a
  dynamic data model (based on DOM), but it apparently did not get
  implemented yet.

    Any hints are appreciated, thank you!
     Jaro
