how to create references between data models so that they are "navigable"? #194

I think (and this may be related to JSON-LD, but I am not totally sure), it would be nice to have a way when i define a reference to a entity described by another schema, that some how, at the schema level I can "navigate" to the associated schema.

maybe these specs can be of use?
