Semantic Web framework to publish semantically-annotated content from free-tagging. Provides a way for users to define meaning(s) of their tag(s) using URIs of Semantic Web resources (such as URIs from dbpedia, geonames … or any knowledge base), and then annotate content with those URIs rather than free-text tags. Tag meanings can be shared between people, providing an architecture of participation to define and exchange potential meanings of tags within a community of users.
