[Odrl-version2] ODRL Relation attribute for an Asset

[David Martin]

Renato,

I've been looking in some detail at the ODRL Common Vocabulary in 
connection with some ONIX Licensing Terms work.  I noticed that the 
values proposed for the Relation attribute for an Asset are:
-  target: The Asset is the primary object of the Policy
-  outputUID: Specifies the UID to be used for the output Asset

Three things strike me here:

1.  Shouldn't the nomenclature be consistent?  Either "target" and 
"output", or "targetUID" and "outputUID" (preferably the former)?

2.  Is the definition of "target" still correct?  Through your recent 
exchanges with Francis, I think we have now established that a Policy 
can include several Permissions relating to different target Assets.  So 
should the definition refer to "Permission or Prohibition", not 
"Policy"?  And "primary object" is not a very exact form of words.  Does 
it mean "The Asset upon which a permitted or prohibited Action is 
performed"?  Or are there use cases which require a looser definition?

3.  Should the definition for "output" be more consistent with the 
definition of "target"?  Something like "The Asset which is output from 
a permitted Action"?

I also have a query about the Constraint name value which is shown in 
the current draft as "system device", with "device" shaded yellow to 
indicate that it is new.  Is "device" a candidate to replace "system"? 
Apologies if I've missed some discussion elsewhere...
