SKOS-Thes: An extension to SKOS based on the ISO 25964 data model
The ISO 25964 standard, published in 2011, covers all aspects of developing thesauri and setting up mappings across vocabularies to encourage high quality information retrieval across networked resources. ISO 25964 is hosted by NISO and replaces the previous standards ISO 2788 and ISO 5964. The goals of ISO 25964 are similar to those of SKOS, the W3C standard for sharing and linking Knowledge Organization Systems on the Web in a simple way.
Under the leadership of Johan De Smedt, correspondences were established between the data models of ISO 25964 and of SKOS. In parallel, an extension to SKOS, SKOS-Thes, was created as a namespace of OWL properties and classes for features of the ISO 25964 data model not covered by SKOS itself. The namespace document was edited by Johan De Smedt and Antoine Isaac with input from Stella Dextre Clarke, Jutta Lindenthal, Marcia Lei Zeng, Douglas Tudhope, Leonard Will, and Vladimir Alexiev and was previously hosted by the company TenForce.
DCMI is hosting the SKOS-Thes namespace to ensure its long-term availability and maintainability. If ISO 25964 is revised in the future, DCMI can make corresponding changes in the SKOS-Thes namespace.
