Okay, let's leave this in the "horses for courses" bucket for now.

More than anything else, let's get a somewhat clean list of SPARQL
endpoints that enable users and user-agents explore what's depicted in
the LOD Cloud pictorial.

It should be helpful after its been transformed into RDF :)

I don't know, but this ultimately a voluntary exercise etc..

BTW -- what is the RDF triple/quad store behind your various endpoints?

Understood, and that's partly why we at OpenLink Software have embarked
upon this particular exercise i.e., attempt to fix what's making folks
feel the way you describe.

Is there an actual data dump URL that I've overlooked?

I plan to publish the data in RDF as just another contribution to the
LODCloud i.e., a dataset about SPARQL endpoints that enable end-users
(people) and user-agents (software) explore said cloud via queries etc..

I don't know any other way.

It will be CC-BY SA or whatever is the most open license in use these days.

That's okay, most your endpoints actually work so I only need you to
confirm what engine sites behind the SPARQL Query Service endpoint .
