OCaml-RDF

What is OCaml-RDF ?

OCaml-RDF is the OCaml bindings to Redland's Librdf, Raptor 2 and Rasqal. These are libraries to parse, print, load, store, manipulate and query RDF graphs, used in semantic web applications.

OCaml-RDF is an OCaml library to manipulate RDF graphs. It is still in early development stage.

Implemented features:

• Three storages available: in memory, in a MySQL or in a Postgresql database,
• Ability to define your own storages,
• Transactions,
• Importing from and exporting to RDF/XML and Turtle formats.

OCaml-RDF is hosted on the OCaml forge

The development started in late november 2011.
