Hi Daniel,

Apologies for slightly slow reply.

Suggest you just name this the DataDeck as per http://wiki.ckan.org/DataDeck

Agreed. I've tried to start having a middle layer in dpm but more work
is needed.

Is it possible for you to fork dpm and work on that and then make pull
requests rather than putting in GUI layer? If you start out small we
can get an idea of where this is going and move pretty quicly.

DataDeck as per above.

Agreed. See previous.

Python now supports 'subpackages' so this is possible. For the moment
it may be best to keep this in a separate repo though can be persuaded
either way. Already have:

<https://github.com/okfn/datadeck>

Which we could deprecate / rename and replace with your code :-)
