Welcome to LOV, your entry point to the growing ecosystem of linked open vocabularies (RDFS or OWL ontologies) used in the Linked Data Cloud. Here you will find vocabularies listed and individually described by metadata, classified by vocabulary spaces, interlinked using the dedicated vocabulary VOAF.

You will enjoy querying the LOV dataset either at vocabulary level or at element level, exploring the vocabulary content using full-text faceted search, and finding metrics about the use of vocabularies in the Semantic Web.

Not finding your favourite one? Suggest a new vocabulary to add to LOV!

Help us and suggest a new vocabulary !
Vocabulary spaces (262):

Classifying vocabularies is a brand new challenge for Library Science, and no existing classification scheme seems to fit the need so far. Unless we missed something, and in that case we are open to suggestions from the librarian community.

This feature is highly experimental and its structure is unstable, likely to be often challenged by the growth of LOV, but gives a high-level view of the ecosystem, complementary to other ways of exploration such as SPARQL endpoints, full-text search, and navigation through links.

Vocabulary Spaces are also used as one of the facets in the full-text search.
