Sparqling a nodelist List

ok, this is rather trivial but good as a reminder for myself. Having the list of XMPP Publish-Subscribe Nodes noted down as in my scratch file figuring out what nodes I use is pretty easy with SPARQL:

just do a

SELECT ?node ?maker_name
 ?node <> <> .
 ?node <> ?maker .
 ?maker <> ?maker_name

and receive a list of xmpp-URIs and their maker/owner. Try this at my new ARC2 based sparql endpoint or via GET
