Lots of tools

• Lots of tools are available. Are listed on W3C’s wiki:

• • RDF programming environment for 14+ languages, including C, C++, Python, Java, Javascript, Ruby, PHP,… (no Cobol or Ada yet…)
  • 13+ Triple Stores, ie, database systems to store datasets
  • SPARQL “endpoints”
  • converters to and from RDF
  • validators for RDF, OWL, …
  • etc

• Some of the tools are Open Source, some are not; some are very mature, some are not: it is the usual picture of software tools, nothing special any more!

• Anybody can start developing RDF-based applications today
