I'd like to discuss their practical usefulness first. While I agree
the five star system is a fantastic PR measure, I'll personally take a
3 star CSV table over a 5 star RDF graph any day if I want to create
an open data application. Many fantastic formats, including things
like Shapefiles, JSON data, SVG, etc. would be under-valued in this
system, while important factors such as the availability of a contact
person, the completeness and detail level of the data, the frequency
of updates etc. remain irrelevant. 5 star is about conformity to the
ideas of a particular branch of the academic community, not use value.
Yet by displaying them on CKAN we would suggest just that. Wouldn't we
rather try to display some proper indicators of quality?

p.s. I actually worry about the consequences of the 5 star system on
open data as a political goal. This classification simplifies the
problem of releasing data, giving it a clear advantage in
communications with non-technical policy makers. Yet this could lead
to other important factors (such as the ones mentioned above) not
being considered, while a lot of effort is put into translating things
into RDF for no particular reason.
