RDFCore is a pure perl implementation of RDF storage, parser, serializer and query.

The storage functionality is basic - store, delete, query statements, where query means ask about existence or count or retrieve statements conforming given mask of subject, predicate, object. Three storages are available - in memory, file DB_File and DBMS PostgreSQL.

The parser supports full RDF/XML syntax including aboutEach attribute though it became obsolete.

The serializer attempts to preserve anonymous nodes and to compact xml a bit grouping statements with common subject.

The query language is rather focused on resources than on statements.
