Yes, but that still doesn't link to specific entities, which is why
it's useful to include URLs. See the description of Linked Data
someone posted earlier in the thread.

I don't really see why there's anything wrong with providing links to
other site as well as wikipedia, as long as they are a useful
reference point. For example, any POIs that I add that have a website,
I'll link to that (it's also a good source to get their address and
other useful information from, so it's good to list that as a source),
or if there is another information site that has information about
that thing where wikipedia doesn't (often due to the 'notability'
restrictions), then I'll link to that instead. It all makes the
dataset richer, and links the users of the data up with further
information about that object.
