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. You need to be able to get it, you need to be able to change it, you need to be able to share it, you need to be able to handle data forks and merges (just as we do with source using patch, diff, and source control).
