Hello all I'm pleased to announce the first publication of "Vocabularies of a Friend (VOAF) - Friendly vocabularies for the linked data Web" Data sets published in the framework of the Linked Open Data Cloud are relying on a variety of RDFS vocabularies or OWL ontologies. The aim of VOAF is to provide information on such vocabularies, and in particular how they rely on each other. VOAF defines a network of vocabularies the same way FOAF is used to define networks of people" VOAF is of course a clear homage to FOAF, which is the hub of the network : more than half of the listed vocabularies rely on it one way or another. I've asked Dan Brickley a couple of days ago if he did not mind this friendly hack. Without answer from him, I just went ahead following the adage "Qui ne dit mot consent". More at http://www.mondeca.com/foaf/voaf-doc.html The VOAF dataset is available as linked data at http://www.mondeca.com/foaf/voaf-vocabs.rdf This is a work in progress, still a bit sketchy, which hopefully will benefit from the community feedback. In particular I've tried to link the vocabularies to the CKAN datasets using the Tag ontology, for example making explicit the link from http://xmlns.com/foaf/0.1 to http://ckan.net/tag/format-foaf Instead of re-inventing a specific attribute I've reused Lexvo, MOAT and Tag ontologies like in the following, which is might be a bit convoluted for the purpose at hand. <voaf:Vocabulary rdf:about="http://xmlns.com/foaf/0.1"> ... <lvont:representedBy> <moat:Tag rdf:about="http://ckan.net/tag/format-foaf"> <tag:name>format-foaf</tag:name> </moat:Tag> </lvont:representedBy> ... </voaf:Vocabulary> I've made sense of quite a bunch of CKAN tags in terms of corresponding vocabulary used, but there are still quite a few vocabularies w/o corresponding CKAN tags. If people in charge of CKAN tags see anything I've missed pleas feel free to push it to me. And of course any feedback on whatever you would like to see added/modified/deleted is welcome. Thanks for your attention.
