Hi Peter,

If it can be sent over HTTP, and can express hyperlinks in a standard way, and can express arbitrary attribute-value pairs in a standard way, then it can do Linked Data.

Best,
Richard

It seems to me that the boundary is triples, i.e., RDF.  What linked data adds is nothing more than pragmatics.  (Not that pragmatics isn't important.)

However, there's a thin line between saying “we enable LD with JSON” and “JSON-LD is how you do LD”. The JSON-LD spec really ought to say only the first thing, but slips into implying the second too often.
