implementing a moat server
This night I installed a moat server to serve up the tags I use to tag in my RDF files, like first rough scratch. You will find it at tags.b4mad.net …

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
FORM <http://b4mad.net/RDF/goern/nodelist.rdf>
WHERE {
?node <http://www.w3.org/2000/01/rdf-schema#type> <http://jabber.org/protocol/pubsub#node> .
?node <http://xmlns.com/foaf/0.1/maker> ?maker .
?maker <http://xmlns.com/foaf/0.1/name> ?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…
