[ckan-dev] Views on data through the web

[Francis Irving]

Yep, I hope we can share the SQL data server.

I think the core of it is the same for each of us - and one day we'll
both want multiple server scaling of some sort, and no doubt lots of
other things.

It would make sense for it to be a separate open source project.

Quite surprising that we've both settled on SQLite for this...
(Everybody else busy talking about CouchDB and MongoDB...)
