p5-RDF-Core

Object oriented Perl modules for handling tasks related to RDF

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.
