RDF Schema

Go up to Terms and Definitions

RDF Schema provides a W3C data-modelling vocabulary for RDF data. RDF Schema extends the basic RDF vocabulary with constructs for describing classes, properties, subclass relationships, subproperty relationships, domains, and ranges.

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 OWL.

RDF Schema differs from a general schema. RDF Schema specifically defines vocabulary structure for RDF data.

W3C RDF Schema 1.1; specialised for use in the FX Demo Reference Architecture.

RDF Schema is not equivalent to OWL. RDF Schema provides basic vocabulary modelling for RDF data. OWL provides a more expressive ontology language with formally defined meaning for the Semantic Web.

An RDF Schema model defines FXTrade as a class, ConfirmedFXTrade as a subclass of FXTrade, and hasCounterparty as a property whose domain is FXTrade.
