Why don’t you use JSON-LD to model the suite of use cases and OCF resources in my two demos and we can then ask web developers and SMEs for their comments on the side by side examples?  This would ensure that we cover a broad range of requirements as provided by the large set of use cases.

In respect to tooling, it took very little time to write the JSON to RDF translator, and making it easy to the exploit the mature tooling for RDF for reasoning over rich models of things, their relationships and context. Are you interested in helping with an exploration of semantic reasoning for the Web of things?
