ckanext-semantictags offers the possibility for Open Data Portals to tag their datasets with semantic resources. Features include: relating CKAN tags to semantic resources, defining custom RDF predicates for linking datasets with the Linked Open Data cloud, and connecting several CKAN instances through the use of global semantic tags. CKAN offers from core an RDF description of datasets, but linking datasets to external semantic resources was not possible before. SemanticTags fills this gap. Requires CKAN >= 2.4. Access the management interface at yoursite/semantictags. Developed in the context of the STODaP research project at Federal University of Rio de Janeiro (Brazil) and University of Bonn (Germany). Requires DB migration via paster command.
