"Repository" and "source" are not the same thing. I strongly agree that there needs to be a single authoritative repository; it's the joke about the man with two watches again. Each datum must also have a single authoritative *source*, but there may be many such sources entering data into a single repository, (or a single source and many repositories, if you partition the data.)
