<a name="Overview" id="Overview"></a><h2> <span class="mw-headline"> Overview </span></h2>
<p>RDFS is a general-purpose language for representing simple RDF vocabularies on the Web. Other vocabulary definition technologies, like <a href="/2001/sw/wiki/OWL" title="OWL">OWL</a> or <a href="/2001/sw/wiki/SKOS" title="SKOS">SKOS</a>, build on RDFS and provide language for defining structured, Web-based ontologies which enable richer integration and interoperability of data among descriptive communities.
