Re: [poe] Support JSON-LD


I think this has been said before, but to just to clarify and support 
the opinion.
The JSON representation should be the JSON-LD simply with the @context
We define and provide the @context which will give us a representation
 in JSON that we agree on.

If people define their own JSON representation that is their choice, 
but with the semantics removed and a different representation then its
 basically not interoperable.
They could provide something like an R2RML mapping back to JSON-LD or 
RDF from their JSON format, but basically thats not really relevant to

I suspect there is concern that a JSON-LD object with the @context 
removed is problematic? 
If so lets break down what exactly the perceived issues are.
