Here's my thinking: The whole point of the semantic web is to get away from relying on terms. Why would you intentionally want to become dependent upon labels (terms)? Label's are not identifiers; they are annotations. There is no uniqueness guarantee. A concept can have many labels and many co

I agree with Chime points. I will add that the great missing feature or tool is versioning and depreciation handling. I had a customer see a GUID URI once and freak out and almost drop a contract. Readability and maintainability is important. Enforcing uniqueness in literals is not part of the

Well it seems like a utopian model, but at the same time in academics you are judged on your papers and grants. So without some exclusivity it is difficult for academics to cope. Obviously with a study that couldn't be done without a great deal of cash, collaborations are vital...but as much as
