Sesame is an open source RDF database with support for RDFS inferencing and querying. It offers a large scale of tools to developers to leverage the power of RDF and RDF Schema. It is a Java framework, there is also a python wrapper.

In addition to offering ready to use native and database-backed quadstores, it also offers an extensible API to build other stores upon. There are many third-party stores that can be used through the Sesame Sail API. Examples are 4store, Bigdata, and OWLIM (which offers optional support for OWL reasoning).

The Sesame SAIL API can also be used to extend the functionality of such stores. Geospatial and free-text indexing and search can be added to Sesame compatible quadstores with the IndexingSail extension.
