DDI RDF Vocabulary

The subject of this group are discussions on RDF vocabularies which are related to DDI (Data Documentation Initiative). Currently this group is focusing on two areas: XKOS, an RDF vocabulary for describing statistical classifications, which is an extension of the popular SKOS vocabulary; and the DDI RDF Discovery vocabulary, for publishing metadata about data sets into the Web of Linked Data. Other vocabularies are also being considered for development in future.
