JSON schema and entity resolution

Protobuf isn't compatible with JSON schema-based projects such as Search/Beacon so they rely on a second-hand Schemablocks representation of some elements.

Ideally pehnopackets should be directly discoverable and useable in JSON schema projects with its own namespace e.g. schema.org findability.

@jfuerth, can you expand on this?

Start with the issue description and clarify how Phenopackets should relate to Protobuf, Schemablocks, JSON Schema, and schema.org. Define the namespace and representation needed for direct discoverability and usability in JSON schema projects; the work is done when that design is agreed and implemented.
