Re: Driving JSON-LD framing specs from SHACL model

Hi Thomas,

we had two breakout sessions, in September 2023 [1] (during TPAC) and in 
March 2024 [2] (during Breakout day) around this topic. You might find 
the minutes and slides presented there interesting. We might continue 
the discussion during the upcoming TPAC or further events (this is still 
in discussion).

Intuitively, I would use a similar approach to the one you used in your 
SHACL-to-context conversion: a dedicated predicate used to annotate the 
node shapes (for 1) and the property shapes (for 2).
