Hi Lars,

Of course EDM can be seen as a modular profile built on components defined elsewhere, e. g. you could have a profile that defines how to express rights metadata (must have one edm:rights element that must contain a URI pointing to a closed list of pre-defined rights statements and if the rights statement is one that mandates attribution (e. g. CC BY) the rights information also must contain a ex:attributionExample element that shows whom to attribute it to). Then harvesters could search for content that adheres to that profile an know exactly how to extract the relevant information. In a way a bit like how Java interfaces work.

Could such a component be like
Note that I'm not sure this one is full independent from EDM on the theoretical side. But once again, the proof of the pudding is in the eating: some have used it in a non-full-EDM context:
