Hi Pascal,

You re making claims that are best verified in a live environment i.e.,
one of the fundamental virtues of a SPARQL endpoint.

We have many live endpoints:

[1] http://dbpedia.org/sparql
[2] http://dbpedia-live.openlinksw.com/sparql
[3] http://linkeddata.uriburner.com/sparql
[4] http://lod.openlinksw.com/sparql

many others published by others.

We even share documents regarding configuration [1].

No, you are observations from a setup constructed by you. I am
requesting that you demonstrate your claims via a live SPARQL endpoint,
not a paper. I am requesting this for a specific reason, so can you
provide this or not?

Again, until you provide a live SPARQL endpoint you will not actually
understand why "Anytime Query" actually exists i.e., you "..is great but
does not ensure complete answers" speaks for itself.

Can you provide a live SPARQL endpoint or not?
