Domains and Ranges

Domains and ranges are specified in the definitions of RDF properties in order to enable inferences about the things described using those properties. As defined in W3C's RDF Schema specification, a domain is the class to which the subject of an RDF statement using a given property belongs, and a range is the class of its object (value). Domains and ranges, which were added to the definitions of numerous DCMI properties in 2008, were largely changed by the DCMI Usage Board in 2018 to the less rigidly logical "domain includes" and "range includes".
