Thanks Markus, very interesting stuff. Looks like I need to read up
more on RDF & things. :)
I'm not sure about whether to use prefixes. What are the pros/cons in
terms of JSON-LD?
But as Michiel said earlier in this thread, in the end it doesn't
really matter what format we use for storage, as at least on the
JavaScript front we provide the library to access the data. That can
still convert to "pure" jCards or whatever.

>> Please note that you are free to define how your fields are named in the context. I simplified some here, e.g., "street-address" to just "street" and made sure you don't have to use prefixes. If you would be fine with using prefixes such in v:address in your JSON-LD documents the context could be simplified to something like:
