Re: Constraint V Refinement

Hi Simon, I find the use of refinement with Asset/Party Collections more straightforward (than action refinement V rule constraint).

The Collections are member-based and the refinement (which can be any type of narrowing query really) results in a subset of members.

When i look at Example 14 here: https://www.w3.org/TR/odrl-model/#constraint-action <https://www.w3.org/TR/odrl-model/#constraint-action>
I can clearly see that “printing at 1200dpi”  is narrower semantics than just “printing”.

So, is “streaming on Youtube” narrower semantics than just “streaming”?

Is it the same “concept" as a geospatial constraint?
Streaming in Australia versus Streaming (anywhere) ?

Both cases seems to imply that you are still streaming but in different physical or virtual worlds.

Perhaps our only way forward would be for ODRL Profiles to document why they choose the approach they did….?
