Commons RDF aims to provide a common library for RDF 1.1 with implementations for common Java RDF frameworks like RDF4J, Apache Jena as well as for other libraries such as OWLAPI, Clerezza and other JVM languages.

The main motivation behind this simple library is to revise an historical incompatibility issue between these toolkits. This library does not pretend to be a generic API wrapping those libraries, but is a set of common Java interfaces for the RDF 1.1 concepts, e.g. IRI, BlankNode, Graph, accompanied with unit test cases for their expected behavior, and a simple implementation, which main purpose is to clarify the tests and interfaces.

In particular, Commons RDF aims to provide a type-safe, non-general API that covers RDF 1.1.
