| RDF Schema provides a W3C data-modelling vocabulary for [[dido:99_annexes:99_annexes:annex-b-terms-and-definitions:r:rdf|RDF]] data. RDF Schema extends the basic RDF vocabulary with constructs for describing classes, properties, subclass relationships, subproperty relationships, domains, and ranges. | RDF Schema provides a W3C data-modeling vocabulary for [[dido:99_annexes:annex-b-terms-and-definitions:r:rdf|RDF]] data.

| RDF Schema supports semantic interpretation of RDF graphs by defining vocabulary-level relationships and constraints. RDF Schema provides more structure than RDF alone and less expressive power than [[dido:99_annexes:99_annexes:annex-b-terms-and-definitions:o:owl|OWL]]. | RDF Schema supports semantic interpretation of RDF graphs by defining vocabulary-level relationships and constraints.

| RDF Schema is not equivalent to [[dido:99_annexes:99_annexes:annex-b-terms-and-definitions:o:owl|OWL]]. RDF Schema provides basic vocabulary modelling for RDF data. OWL provides a more expressive [[dido:99_annexes:99_annexes:annex-b-terms-and-definitions:o:ontology_language|ontology language]] with formally defined meaning for the Semantic Web. | RDF Schema is not equivalent to [[dido:99_annexes:annex-b-terms-and-definitions:o:owl|OWL]].
