Domain Includes and Range Includes

Domain Includes and Range Includes are used to suggest classes to which, respectively, the subject or object of an RDF statement may belong. In contrast to formal domains and ranges, domain and range includes are less about enabling logical inference than about helping users understand how a given property is intended to be used. Drawing a lesson from the successful Schema.org initiative, the DCMI Usage Board decided in 2018 to soften many of the formal domains and ranges added in 2008 to domain and range includes.
