The main idea is to find entities in selected reference datasets (controlled vocabularies, ontologies) corresponding to the literal values in the metadata records. The obtained entity identifiers are further used to generate new RDF triples, representing outbound links. Within CMDI the SKOS-based vocabulary service CLAVAS,\furl{https://openskos.meertens.knaw.nl/} which will be supported in the upcoming new version of CMDI, can be used as a starting point, e.g., for organisations. In the broader context of LOD Cloud there is the Open Knowledge Foundationâs Working Group on Linked Data in Linguistics, that represents an obvious pool of candidate 448 datasets to link the CMD data with.\furl{http://linguistics.okfn.org/resources/llod/} Within these \xne{lexvo} seems a most promising starting point, as it features URIs like \url{http://lexvo.org/id/term/eng/}, i.e. based on the ISO-639-3 language identifiers which are also used in CMD records.448 datasets to link the CMD data with.\furl{http://linguistics.okfn.org/resources/llod/} Within these \xne{lexvo} seems a most promising starting point, as it features URIs like \url{http://lexvo.org/id/term/eng/}, i.e., based on the ISO-639-3 language identifiers which are also used in CMD records. 449 449 \xne{lexvo} also seems suitable as it is already linked with a number of other LOD linguistic datasets like \xne{WALS}, \xne{lingvoj} and \xne{Glottolog}. 450 450 Of course, language is just one dimension to use for mapping.
