We need a way to group resources by various different factors. The most important of which is timeseries.

The model will look like

Package <o2m> resource_group <o2m> resource

The use cases to this are outlined in this email. ​http://lists.okfn.org/pipermail/ckan-discuss/2011-February/000887.html

The new field was outlined in

​http://lists.okfn.org/pipermail/ckan-discuss/2011-February/000887.html

it says

Can be "data", "metadata", "service", NULL. There is a need to do this for UKLP where some of the data associated with a package is metadata, some is data and some could be a service.

This is a meta-ticket to hold all of the work on refactoring forms, validation and model-synchronization in CKAN.

The Issue

From #926:

The current formalchemy setup conflates view, controller and model code in a way that makes it hard to debug and customise.

From ​http://lists.okfn.org/pipermail/ckan-dev/2011-January/000181.html:

... FormAlchemy, in retrospect, was probably a mistake as it merges too much model/validation/form generation into one thing.

At least 3 functions involved [in this area]:

1. Generating (or just filling) a form template with 'form data' (and errors)
2. Converting model data to form data (also happens for APIs in fact) -- let's call this 'dict-ization'
3. Converting form data to model data (and validating) (inverse of previous step)
