The Perl RDF project aims to be a pure-perl RDF framework implementation with an emphasis on extensibility, API stability, and the presence of a test suite. Currently, the project includes: * RDF::Query, a SPARQL (and RDQL) query engine supporting RDF::Trine, and RDF::Redland. * RDF::Trine::Parser, a set of native RDF parsers for RDF/XML, RDFa, Turtle, RDF/JSON, TriG, N-Triples, and N-Quads. * RDF::Trine::Serializer, a set of native RDF serializers for RDF/XML, Turtle, RDF/JSON, N-Triples, Canonical N-Triples, and N-Quads. * RDF::Trine::Store, a triplestore API with DBI-based implementations for MySQL, PostgreSQL and SQLite, based on the Redland schema. * RDF::Trine::Iterator, iterator classes for variable bindings and RDF statements, used by RDF::Trine::Store, RDF::Trine::Model, and RDF::Query. * RDF::Trine::Namespace - A convenience class for easily constructing RDF node objects from URI namespaces. * RDF::Endpoint - A SPARQL endpoint based on RDF::Query. * RDF::LinkedData - A mod_perl2 handler for serving linked data from an RDF::Trine triplestore.
