textproc/p5-RDF-Core 0.51_1 DragonFly

RDF::Core 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.
