I've created a draft JSON-LD fork in order to actually enable round tripping with RDF: https://gist.github.com/ColinMaudry/5163ecade149a837aa25694fdd7ac46f. It's still incomplete, but it gives an idea.

And here is how it behaves when processing the JSON to RDF with the context: http://tinyurl.com/hdza9yp

Suggestions if we want to go further in that direction:

• type value should either be a keyword that we can resolve to a URI (ex: local-government) or a URI
• As-is, themes values cannot be used in a UI in another language than English. A pity for French data :) Setting up a list of themes URI would enable multilingual support. As for type, in the JSON, the themes value could either be lower case keywords in English or URIs
• I'm not very comfortable with property name in plural form. I assume it's a hint to know that the value is an array.
