I second that suggestion. By using e.g. Atom you also get a way of
receiving updates about changed datasets in a machine readable way.

We used Atom as the carrier for RDF data items in a project I was
involved in  (swedish national legal information system). There are
many benefits and it is easy to get started as there are many tools to
create and consume Atom feeds.

If necessary you could extend Atom entries with information about the
specific datasets, or you could just use Atom to carry the pointer to
the rdf for a specific data set (described with whatever vocabularies
necessary). Or use both approaches simultaneously.

With regards to open data my experience is that you have some basic
information you want to capture:

Title (e.g. "Vehicle licence data")
Summary
Publisher
Categories
License
Timestamps
Link to about API page
Link to actual data set (if available)
Link to RDF data about dataset (if available)

Most of these are already available in Atom
(http://www.ietf.org/rfc/rfc4287.txt).

You could add licensing info as well if there is a simple way of capturing that.

Anyone who would like to contribute ideas for this in practice is
welcome to join the opengov catalog project here:
