Depends what you mean, but there is Encyclopaedia Britannica, OED, ODNB,
DMOZ, CDDB, IMDB, Everything2, H2G2 etc. which are all compete with
Wikipedia in one way or another, are all commercial (to some degree),
and all (apart possibly from Britannica) accept volunteer contributions
of one kind or another (but moderate them).
But yet again, the wikipedia comparison doesn't work, and the
Musicbrainz comparison does. Musicbrainz, CDDB, and AllMusic are all
doing almost exactly the same thing, but MusicBrainz is the only

There's also The People's map, which I wouldn't dismiss totally out of hand.

Obviously, I have huge benefits of hindsight, and if I didn't have the
mistakes of OSM for reference, I wouldn't have thought of many of these
* I would use PostGreSQL :-)
* I wouldn't use ruby or rails
- it uses way too much resources server side (the file should be able
to stream to the user and not be pre-built in RAM at all on the server -
Rails seems to use several times the size of the output file RAM to
serve the file)
- it disconnects you from the benefits of a real database (triggers etc.).
* I would import all the data I could find with just attribution into a
central database, and make a system to browse it giving credit where
needed (like how google maps gives credit). I.e. Tiger, Canada's data etc.
* I would make a system that let users edit data into another "layer"
from the above (including letting them mark things that replace things
from the other layer, without actually removing them from the other
layer), but I would make those users assign rights to the project.
* I would probably have a nodes/segments/[groups of segments] model,
where groups of segments are tagged - so all segments of motorway would
be in one group, all segments of bridge in another group, all segments
making up "My Street" would be a group etc., and I'd allow groups to be
used to mark relationships like turn restrictions (I'm not sure
/exactly/ how to do that)
* I'd make segments bezier curves (It's too obvious for the 'patent' to
* I would release the data under multiple licenses, and I would put
effort into getting commercial users to use the data and pay for it.
