Re: Introducing Vocabularies of a Friend (VOAF)

Sounds very interesting initiative. Based on my understanding, I think it
should be possible to write a tool that read any OWL document and generate a
VOAF document. May be Swoogle could be a good starting point, but not sure
how the API can provide the list of ontology namespaces through the REST
API. The imports section would corresponds to the imports statement. The
tools would count the number of classes and properties in the ontology
namespace. It would be interesting to aggregate all this information and see
which vocabularies have the most influence using SNA algorithms.

Best regards
