So its a good thing we already have two of these :) - We need to
clarify the workflow for the local data validator though, given that
the default way of creating the model increasingly tends to be the the
web ui. Maybe osvalidate should expand "de-bund" to
http://openspending.org/de-bund/model.json in the background.

Requires some Java coding but I think the CKAN guys need to do it
anyway, maybe we can just jump on the bandwagon once they're done.

I think Fusion Tables doesn't help us there: its also not primarily
about data cleansing; although that may change. So this just
introduces more abstraction without much gain.

It does that at the moment, but its kind of hard to explain. Plus I've
never actually seen OS's CKAN integration work, really need to do

Not sure how this would work: the bot would try to parse the CSV or
also attempt to validate using an OpenSpending model?
Can we get DSPL in CKAN, please?
