Driving JSON-LD framing specs from SHACL model

Hello SHACL & JSON-LD lovers

I have SHACL specs. I also have APIs that return JSON-LD. The JSON-LD is
built from RDF using a manually maintained context + JSON-LD framing specs.

My question is how I could bridge my SHACL with my JSON-LD context +
framing, to have a completely model-driven architecture. In other words can
I generate the context + framing from the SHACL (probably using some extra
annotations).

Generating a default context from the SHACL is relatively easy [1]. My
question is on the framing part, specifically on the hierarchical structure
of the JSON. How can I indicate in the SHACL model :

   1. which shapes are the roots of the JSON-LD structure ?
   2. which properties use embedding in the JSON-LD structure ? ("@embed":
   "@always") and which should be simply references to URIs ?

The ability to specify the (or a) hierarchical view of my graph structure
could be useful, even for an RDF/XML serialization, or an HTML rendering of
a dataset.

Any ideas or pointers on this ?

Cheers
Thomas
