Extend license restriction with branch

[nicholascar]

Is it possible to implement in SHACL such an instance-specific restriction branch condition test:

IF Dataset stored in EUDM system
THEN license must be as per current restriction (in .../license/ register, with 1+ permissions)
ELSE //Dataset in EUDM catalogue but stored elsewhere
THEN no license allowed to be present

This is due to Adam stating this is the logic of the licenses he's been asked to adhere to as CSIRO legal want to make no license claims for data stored elsewhere in case we characterise the license information incorrectly.

That is related to the SPIN CONSTRUCT ops that I was able to successfully implement in https://w3c.github.io/sdw/proposals/ssn-extensions/ but haven't managed to get working in SHACL

This raises the issue of how a Implementation Resource Description could be mixed, rather than having a single resource with a conformsTo to SHACL or SPIN.

I think this is modeled by having, in this case, two ImplResDescs, conformsTo SHACL and the other SPIN, each with the resourceRole "Partial Set of Constraints for a Profile" from the Roles vocab.

That way, push SHACL as far as you can but use SPIN if you can't!

Of course, licenses are associated primarily with Distributions ...
