[Odrl-version2] Spatial constraints

[Francis Cave]

I'm not sure that it makes any sense to have "from" and "to" as the operator
in this case. We're not talking about ranges here. 

 

I think that we have to be clear about what a constraint means with respect
to a particular action. Clearly "spatial" is meaningless if applied to an
action such as "derive". It may be worth considering creating a table
showing which constraints can meaningfully be used with each action, and
defining the meaning in each case.

I fully accept that wishing to constrain the "from" would be much rarer than
wishing to constrain the "to", but both are rather more than a theoretical
case.

 

Can we express these as new (range) Operators: from, to ?

 

 <o:constraint name="o:spatial" operator="o:from"
rightOperand="iso3166:AU"/>
<o:constraint name="o:spatial" operator="o:to" rightOperand="iso3166:UK"/>

PS: we had Range in Version 1.1
