RE: odrl:LeftOperand and odrl:Action affinity to odrl:Rule classes

Do I hear SHACL? 😁

Here’s a quick example on how this could look like: https://s.zazuko.com/hAA9xf


Fwiw, there’s also a wiki we created years ago here https://github.com/simonstey/ODRL-SHACL-Shapes/wiki

Yes – I thought about as part of the validation.

I had a brief conversation with Yassir on Monday and explained how there ‘the many layers’ and where SHACL  is useful (grammatical validation) and where it could be a good idea but won’t be performant (evaluation).

Unless someone has already done it - I will try to build a SHACL baseline and put it on GitHub.

Maybe this is where SHACL comes in?

We did discuss this (briefly) many years ago, but decided to let the community define this level of additional rules.

For example, you could conceive a Duty where I had to play a video of a Gambling Warning video each time I showed a Gambling advert (as we do here in Australia!)

Hi,

Has anyone considered the need for explicit affinity from left operands and actions to Rule classes?

Operands:
Example:  odrl:payAmount should only be used in odrl:Duty

Or are there use cases where implicit duties are applicable:

ex:PaymentRefinement            a odrl:Constraint;
                 odrl:leftOperand odrl:payAmount;     # <-- this refinement now looks like a Duty within a Permission
                    odrl:operator odrl:eq;
                odrl:rightOperand "25"^^xsd:decimal.

ex:ActionURI                    a odrl:Action;
                      odrl:action odrl:play;
                        odrl:unit iso4217:EUR;
                  odrl:refinement ex:PaymentRefinement.

ex:Permission                   a odrl:Permission;
                    terms:created "2024-067-03T09:33:36.9180000Z"^^xsd:dateTime;
                      odrl:target ex:AssetURI;
               ex:actionReference ex:ActionURI.

Actions:
Likewise, certain actions shouldn’t have an affinity with rule classes.

An example that comes to mind would be odrl:play shouldn’t be used within an odrl:Duty.

Regards,
