Thanks for the pointer.  Looking at examples for their service specification, e.g. [1], I see that they include LAN & protocol info. To scale well across proxies etc., the Web of Things needs to provide a clean abstraction that is decoupled from the communications layer details. Of course we need to deal with those details, but with a clean separation between different architectural layers.

Another consideration is the way that semantics are expressed.  For a Web scale solution, it makes sense to build upon linked data and the work that has been done on sensor ontologies etc. This is where JSON-LD has the edge over JSON in providing a formal mapping to Linked Data.

I am travelling for the next 3 weeks, and won’t be able to join the calls until I get back to the office. However, I will try to keep up with email where possible.
