SKOS application for interoperability of controlled vocabularies in the field of linked open data

This paper aims to determine the scope of application of SKOS in the Semantic Web. Controlled vocabularies registered in the The Data Hub catalog of RDF datasets that use SKOS were studied. In addition to establishing a typology of vocabularies, authors analyzed the issues related to open access to data through its direct download, its query through a Sparql endpoint and the existence of appropriate licenses. The existing level of interoperability through the definition of mapping relationships between vocabularies are examined. The study concludes that thesauri and classifications are more integrated into the open data environment while subject headings lists have greater interoperability
