This is something you come across when working on practical cases immediately and it is fairly straight-forward but necessary. We extended SSN in SPITFIRE (www.spitfire-project.eu) in these respects and can provide this as a starting point for discussions. SPITFIRE in my opinion is particularly interesting (shameless self-promotion) for providing input to SSN as we combine RDF, ontologies and REST (6LowPAN and CoAP - currently being standardized by IETF) in this project to make sensor networks look like normal Web resources, i.e., development should boil down to the same abstractions like normal Web development - but there is a lot of work you need to do under the hood to support this in a nice way. CoAP will be the standard. The IoT people are going for REST. Ontologies in IoT are all over the place. We need to support this from SSN's side and get the necessary uptake outside the core Web community.
