Re: Unit-Of-Count

Thanks Ben, just trying to extract the real semantics of “unit-of-count”…

From your example, we can see its used to “multiple the amount to pay” (pay per X) as in:

>   :constraint4-1 a odrl:Constraint ;
>     odrl:payAmount "65.28"^^xsd:decimal ;
>     odrl:unit <http://cvx.iptc.org/iso4217a:EUR <http://cvx.iptc.org/iso4217a:EUR>> ;
>     tr:unitOfCount tr:AccessID ;

And then (latter in the example, and ignoring the extended relations stuff for now) it is used to indicate what data to report back on the odrl:inform Duty

> On the 15th of every month you must report usage by providing a list of either Access IDs or Physical IDs:
>   :duty5 a odrl:Duty ;
>     odrl:action odrl:inform ;
>     odrl:timeInterval "15"^^xsd:gDay
>     odrl:operation odrl:xor
>     odrl:constraint :constraint5-1, :constraint5-2 .
>   :constraint5-1 a odrl:Constraint ;
>     tr:unitOfCount tr:AccessIDList .
>   :constraint5-2 a odrl:Constraint ;
>     tr:unitOfCount tr:PhysicalIDList .

Have I got that right?
