Kai Eckert: "The idea is to establish RDF application profiles, i.e., the possibility to write a definition for an own ontology that mixes and matches several other ontologies. A mechanism to link the application profile to the data is needed (e.g., via a void:Dataset) and we would like to promote a best-practice how a client should deal with an application profile, how an application profile can be used to validate data and so on."
