Changes and improvements to be done in a future release (TODO List):

  • test of SPARQL compliance with the DAWG Testcases.
  • SPARQL/update test suite.
  • Datalog and inference :
    • complete test suite.
    • negation for Datalog.
    • documentation and tutorials.
    • datalog expression/function evaluator.
  • in the apache conf file, for each location using the strixdb-handler, the right to make SPARQL/Update requests has to be explicitly specified (SPARQL/Update rights will be managed by Apache httpd rights access).
  • SPARQL functions implemented as plugins (DLL and TinyC code).
  • SPARQL 1.1 upgrade (or at least the COUNT function).
  • use of LuaJit instead of Lua.
  • availability on Linux.

StrixDB is now (quite) a gigabase database. This upgrade provides the following changes:

  • delayed commit (delayed disk synchronization) available.
  • backup and restore of disk file.
  • scheduled backup.
  • databases larger than 4Gb now supported (could now store more then 2^32 triples).
  • lots of concurrent access errors fixed.
  • WARNING: some bugs possible due to the 32bits to 64bits upgrade. (Under test).

Bugs fixed :

  • upload of RDF graph no more limited in size (was limited by  STL string size limit).
  • error in output of literals in compact XML/RDF (using  !ENTITY) is fixed.
