SchemaWeb is a directory of RDF schemas expressed in the RDFS, OWL and DAML OIL schema languages. SchemaWeb is a place for developers and designers working with RDF. It provides a comprehensive directory of RDF schemas to be browsed and searched by human agents and also an extensive set of web services to be used by software agents that wish to obtain real-time schema information whilst processing RDF data. RDF Schemas are the critical layer of the Semantic Web. They provide the semantic linkage that 'intelligent' software needs to extract value giving information from the raw data defined by RDF triples.

The aim of the pOWL project is thus to deliver a PHP and web-based ontology edititing and management solution to the OpenSoure community.
