Ben, apologies for the delayed response. This is a fairly complex issue and can't be answered quickly... For the record, I'm not strongly anti-URNs - indeed I think that URNs have a place, but I'm not 100% convinced that identification of learning objects is one of them! What I think we (as a community) really need to do is to think about our functional requirements of identifiers for learning objects and learning object metadata records. If we can agree on our requirements, then we are better placed to make choices between available technologies. So, this response is simply to say that I am trying to work up an issues paper about the use of identifiers - and that will include my attempt at a statement of functional requirements. I've copied this to the list, so that other people know that something is on the way in due course (hopefully during the next two weeks).
