thank you both for your feedback, that also helped to clarify that we can use duties to put constraints on specific parties.
Now I guess this is possible also for specific assets, for example:

:aPermission
  a odrl:Permission ;
  odrl:action odrl:display ;
  odrl:target :thisApiData ;
  odrl:duty [
    odrl:output :thisWebSiteOnly
  ] .

Makes sense?

Hi Enrico, a Duty is "requirement that must be fulfilled in return for being entitled to the referring Permission”.
A Duty does not constrain the permission action. It tells you what you must do to get the permission.

So, in the above example, you would need a constraint on the display action to state where it can be displayed (eg with deliveryChannel=web or virtualLocation=“url”)

(odrl:output is only used as the id of the asset created from an action, such as derive, extract, translate etc)
