Welcome to OpenVocab

OpenVocab is a community maintained vocabulary intended for use on the Semantic Web

OpenVocab is ideal for properties and classes that don't warrant the effort of creating or maintaining a full schema. OpenVocab allows anyone to create and modify vocabulary terms using their web browser. Each term is described using appropriate elements of RDF, RDFS and OWL. OpenVocab allows you to create any properties and classes; assign labels, comments and descriptions; declare domains and ranges and much more.

Terms managed by OpenVocab conform to the following URI pattern:

http://open.vocab.org/terms/{termname}

You can obtain different representations of a term's definition using URI's like these:

http://open.vocab.org/terms/{termname}.html

http://open.vocab.org/terms/{termname}.rdf

http://open.vocab.org/terms/{termname}.turtle

http://open.vocab.org/terms/{termname}.json
