Toutes ? Hmm...

Toutes ? Hmm...

Il n'y a effectivement pas une garantie d'exhaustivité. Aujourd'hui il y 249 vocabulaires dans LOV. Le principal critère technique est que l'ontologie doit etre déréférencable via son URI.
Extrait de http://labs.mondeca.com/dataset/lov/about/ :

"To be included in the LOV dataset, a vocabulary has to satisfy the following requirements:

• To be expressed in one of the Semantic Web ontology languages : RDFS or some species of OWL
• To be published and freely available on the Web
• To be retrievable by content negotiation from its namespace URI
• To be small enough to be easily integrated and re-used, in part or as a whole, by other vocabularies.

As an indication of what “small enough” means, currently (as of end of 2011), the median vocabulary size in LOV is around 10 classes and 20 properties, and more than 80% of vocabularies have less than 100 elements (classes and properties). The largest vocabulary in LOV is currently schema.org, with more than 500 elements. And of course, to be included a vocabulary has to come under our radar. We monitor as much sources as possible, including the description of datasets in CKAN, announcements on various Semantic Web lists, buzz on Twitter, Google+ etc. But if we have missed your favourite vocabulary, help us and suggest it."

Swoogle est un bon moyen de récupérer des ontologies existantes.

Une page en anglais pour guider les personnes à la recherche d'ontologies. Beaucoup de liens vers beaucoup d'outils de recherche, de dépôt, d'édition, etc.
