Hi all,

Why not use systems for what they where designed to do?

A solution could be to integrate couchdb with a prober version control
system (darcs, git, svn, ...) and keep a history listing attached to the
document.

I thought that couchdb could send messages to a registered Erlang process
for handling the versioning, when the document was
created/updated/deleted. It would then be possible to write different
callback handlers for the different version control backends.

The tricky part as I see it, is how to retrieve the revisions from the
version control. The attached history could come in handy here I guess.

Does this make sense?
