Hello
There are ongoing discussions under orion on github about this important topic

https://github.com/telefonicaid/fiware-orion/issues/1516

https://github.com/telefonicaid/fiware-orion/issues/1053

This is of course important to all of us and not only to orion, I suggest you read these threads and intervene!

Personally I believe that JSON-LD is THE solution, not only to provide  semantic references and unique URIs for existing NGSI identifiers , but also to support extension of  the current NGSI data model, which is sorely limited : basically it is an entity-centric  arborescence  and we would need more of a graph-based model (à la RDF)  : this is what JSON-LD provides, making it possible to describe inter-entity links, which are needed to, among others, support  truly RESTful (HATEOAS) APIs
