ckanext-semantictags

CKAN SemanticTags plugin offers the possibility for Open Data Portals to tag their datasets with semantic resources.

What can you do with the SemanticTags plugin?

With the SemanticTags plugin you can:

  • Relate your CKAN tags to semantic resources;
  • Define custom RDF predicates for linking your datasets with the Linked Open Data cloud
  • Connect several CKAN instances through the use of global semantic tags

Why a SemanticTags plugin?

CKAN offers from core an RDF description of the set of metadata of each database. However, linking the databases to external semantic resources was not possible. SemanticTags fills this gap, allowing datasets to be tagged with LOD resources.
