RDF Schema is a language for describing vocabularies in RDF. RDF Schema is a semantic extension of RDF. It provides mechanisms for describing groups of related resources and the relationships between these resources. RDF Schema vocabulary descriptions are written in RDF using the terms described in the RDF Schema specification[1]. These resources are used to determine characteristics of other resources, such as the domains and ranges of properties.

The RDF family of specifications is maintained by the World Wide Web Consortium (W3C). ... RDF can refer to: Resource Description Framework, a W3C specification for a metadata model. ...

RDFSchema defines classes and properties that may be used to describe classes, properties and other resources.
RDF's vocabulary description language, RDFSchema, is a semantic extension (as defined in [RDF-SEMANTICS]) of RDF.
RDF differs from many such systems in that instead of defining a class in terms of the properties its instances may have, the RDF vocabulary description language describes properties in terms of the classes of resource to which they apply.
RDF is an attempt to empower effective creation, exchange and use of metadata on the World Wide Web, and therefore addresses many of the same issues as the Dublin Core.
However, the basic RDF syntax utilised in the examples throughout this paper is not suitable for embedding in HTML documents, due to the inconsistent manner in which it is treated by the current generation of web browsing software, and a special abbreviated syntax [RDF-ABBREV] must be used instead.
The RDF instance of this declaration can be found in Appendix 2, although users and developers should always refer to the Namespace itself for the most definitive version.
