a Strix is a kind of small Owl

StrixDB tools development is motivated by the lack of simple tools to manipulate middle sized RDF graphs. StrixDB is appropriate if you use RDF for interoperability, for graph manipulation, for reasoning, for data driven applications. 

StrixDB provides simple solutions to use RDF without pain  (see Getting Started) :

  • StrixStore : a RDF graph store allowing transactions and rule inference (DOC)
  • VGR (Visual Graph Requestor) another graphical tool to explore RDF graphs.
  • some tools (Lua modules) to parse RDF/XML and download files from internet

Simple because you don't need to bundle together an RDF store, a SQL database, a prolog or a RuleML engine, an Apache server, a Turtle converter and some others tools.

StrixStore uses a native disk-based triplet storage enabling performances and transactions.

  • support SPARQL 1.0, SPARQL/Update and SPARQL/protocol
  • Datalog rules reasoning integrated in SPARQL.
  • graph comparison functions,
  • build-in Turtle Reader and Turtle Writer,
  • database management through  Lua  API.
  • easy to use and deploy : could be used standalone or as server :
    • with httpd (Apache Web Server) server to :
      • download and upload RDF graphs into the RDF store (in XML or turtle format)
      • make SPARQL and SPARQL/Update HTTP requests (with the SPARQL protocol),
      • respond to HTTP requests with dynamic Lua pages
        • created from Lua scripts or
        • created from files with embedded Lua code.
    • standalone as a Lua module (embedded use).
    • standalone as a standard windows DLL (embedded use from C/C++/Java/etc...).
