DERI Galway will host the second VoCamp next week. VoCamp is a series of informal events where people can spend some dedicated time creating lightweight vocabularies/ontologies for the Semantic Web/Web of Data. The emphasis of the events is not on creating the perfect ontology in a particular domain, but on creating vocabularies that are good enough for people to start using for publishing data on the Web. The intention is to follow a "paper first, laptops second" format, where the modelling is done initially on paper and only later committed to code. The VoCamp idea is heavily influenced by BarCamp, although the VoCamp should only have presentations where strictly necessary. Read more on VoCamp.
One of the topics which will be discussed is the Drupal core RDF Schema. As I outlined in the roadmap for RDFa in Drupal 7, deciding on the best RDF classes and properties to map Drupal internal objects is key for a optimal integration of Drupal RDF data into the Semantic Web cloud. There is still debate on some aspects of the schema, for instance when it comes to versioning (node revisions). Some vocabularies sometimes overlap and it is still unclear which properties to use. Same goes for roles, which few vocabularies address at present. SIOC recently added the SIOC Access Ontology Module and I'm looking forward to applying it to the Drupal schema.
