I like this idea in the sense of an experiment. I'm not sure where it will end up, but it could be interesting. As others have pointed out, some kind of conventions must be established around the semantics, and something must be done to avoid redundancy (which leads to inconsistency) and ambiguity. I agree with those criticisms, but if the community also helps develop the schema, it will be interesting to see. What collisions will happen? What will be the result of queries that reach far across disciplines?
