Thanks I will use it like this for the moment, Would it be a good idea to look into an xsd for ccREL?
There is already a good human readable guideline, but as far as I can find no automated way of checking the validity of data structured in ccREL. Looking deeper into OAI-PMH I see that they have some structures available to put rights informationan, although this refers to the metadata itself not the object is describes. Adoption of ccREL in a future version of OAI-PMH could benefit the use of ccREL greatly as well as giving archives a way to more accurately describes the rights status of the works they put out there.
