[Odrl-version2] RE: ODRL-Version2 Digest, Vol 20, Issue 2

[Alapan Arnab]

Hi Susanne, Vicky,
I am just wondering how this core is different to the model I mailed in
January ... I had only the objects you list below with two differences:
1. I do not have a prohibition element because I don't think it should
exist; and I explain my reasons.
2. I split party up into rights holder/producer and user/consumer;
mainly for modelling reasons. This could be condensed into one I think.
