Implement basic JSON LD in the API

Build API that will output basic JSON LD for each LR.
Example:
{
"@context": "http://schema.org/",
"@type": "CreativeWork",
"name": "Designing a treasure map"
"identifier":
}

This will be the starting point for further dev.

Start by locating the API entry point and the representation of an LR, then inspect how resource responses are currently serialized. Implement the basic JSON-LD response described in the issue, including the schema.org context, CreativeWork type, name, and UUID identifier, and verify the API output for an LR.
