I like the layout that you have developed here.

This is somewhat similar to what datapkg create <...> will do. However
we just create a very basic layout (like a simple python package) at
the moment.  An example of current datapkg package along these lines:

<http://knowledgeforge.net/econ/hg/file/tip/econdata/uk_house_prices>

One with a non-pythonic layout is:

We have recently been talking quite a bit about what structure we
should use: be it none (leave it to users) or something like R or
Debian or ... We have also been asking whether we need to support
multiple structures of "just one" (tm). I'd be interested in your
thoughts here.

Yes datapkg allows you to register packages on ckan.net, query
existing packages on ckan. We're just in the process of reworking the
install support -- this is rather more complex than in the code case
because of a need to support package payloads which are e.g. apis
rather than actual chunks of data.

Current datapkg documentation (for trunk):

Instructions for installation are here if you want to give it a whirl:

You'll need to install from the mercurial repository to get up to date code ...
