JSON "schema" for SEG metadata

Summary of the elements being communicated as implemented for the Iowa use case conversion process.

On the high level,it might be nice to use JSON-LD for describing this, to include references to all definitions of the concepts used, but it is not completely clear how that should be done in practice ... See a very initial attempt to get started with this here: https://gist.github.com/fedorov/10dc46e160a615ea187c0b838205eb0f

TODO: investigate the joint use of JSON-LD and JSON Schema!
