Andrew J. Turner (http://www.highearthorbit.com) suggested to me that we need a term for user-created, user-entered, user-discovered, and user-curated data. Of course, if you change "data" to "code" you have exactly what the Open Source Initiative is already doing for software. We could do the same thing for data. Write an Open Source Data Definition, which puts strictures on the attributes of data that claims to be Open Source Data.
