Hi LODers,

The Web of Data is by definition an uncontrolled environment, and by nature
constantly evolving. In this respect the cloud diagram is in my opinion a
snapshot of the LOD at a particular moment. Last version is almost
unreadable in a A4 paper and we passed the era of "the more dataset we have
the better". After the *Expansion era* now it's time for *quality and
reliability era* :) In this context, a "dead dataset" has no place. (i) By
dead dataset I also mean a dataset which is not maintained anymore. (ii) By
dead dataset I mean a dataset which is neither accessible via a dump nor an
endpoint.

(i) may be solved by asking, just like a paper submission, data providers to
update their CKAN dataset profile page for the new cloud diagram release...

(ii) may be solved by filtering, among CKAN dataset collection, those which
are not available (dump and endpoint) since last month.

If this suggestion makes sense, I could help you on the last point by giving
you SPARQL endpoint availability since last month http://bit.ly/dVztWw.

Additionally, some cloud variants may be generated or SVG file could be
given so may contribute to give a particular view of the cloud...
