Still not sure if we shouldn't use the existing setuptools machinery to manage this -- there is already a way to get at the metadata. In any event, I've just made an addition to datapkg that makes it possible to put datapkg_sources as a dictionary in your package's setup.py. Afterwards it is possible to pull the metadata out of the egg. Of course this could easily be changed to save the information in whatever form, indeed if you pass it a string instead of a dictionary it will just write whatever you gave it into the datapkg_sources.spec. The point is, I think that the egg is a good place to stuff this information.

For non-python users, it is always possible to simply put up the datapkg_sources.spec somewhere on the web so they can directly retrieve the data files.

From the docstring::

    This is the implementation for an [egg_info.writers] entrypoint.
    Datapkg adds an argument to setuptools's setup() function called
    datapkg_sources. The argument should be a dictionary of the form:

    .. code-block:: python

        setup(
            ...,
            datapkg_sources = {
                "cra2009" : "http://www.hm-treasury.gov.uk/d/cra_2009_db.csv"
            }
        )

    The result of this is that there will be a file in the egg called
    datapkg_sources.spec that looks like this::

        [sources]
        cra2009=http://www.hm-treasury.gov.uk/d/cra_2009_db.csv

    How do you get at this data? Simple::

    .. code-block:: python

        import pkg_resources
        dist = pkg_resources.get_distribution("ukgov_treasury_cra")
        spec = dist.get_metadata("datapkg_sources.spec")

    and 'spec' will be the contents of the file as a string.

As a user I want to preview a dataset ('resource') before downloading it.

Implementation

This will be implemented as an Extension

NB: This ticket requires a way to get data out of a remote url (the dataset). We do not want to put this data load/streaming into ckan core due to a) complexity b) load problems (do not want to take ckan out by accidentally pulling in a 1GB file)

1. Need a 'data proxy' - see ticket:698 and ticket:888
2. Preview using javascript in WUI - do this in an extension ​http://bitbucket.org/okfn/ckanext-dataapi

Occasionally data4nr removes a data package from its registry. When the latest full data4nr data is imported, these removed packages should be found and removed.
