Everybody loves JSON! However, JSON by itself is pretty meaningless. Well. It has meaning, but only to the original creator of that format. Developers attempt to share any defined meaning via application documentation, usage within code, or even person-to-person conversations. Often all of those exist in places far removed from the JSON document itself. Enter Linked Data. JSON-LD or "JSON for Linked Data" provides a means to connect the terminology in your idiosyncratic JSON documents to world-wide meaning via context files and URLs.
