Re: Constraint V Refinement

Hi,

I do not see a great difference between refinement or constraint because 
its interpretation is not defined (cf. examples in a testbed where an 
algorithm must behave differently in each case), therefore the 
difference is only philosophical to me. And even in this case unclear: I 
would have said constraint, though, for the deliveryChannel, and if 
refinement, refinement of the action (this would be like an "adverb" 
modifying the action rather than an "adjective" qualifying the asset)

Regards,
Víctor

the rule?

refinement on the asset i.e. the video itself? e.g., => "you can stream 
(action) videos whose deliveryChannel is YouTube (asset with 
deliveryChannel == YT)
