Yes, they all use a consistent pattern re. proxy/wrapper linked data URIs.

Re. last.fm folks, if me combine efforts and produce meshes with good 
___domain fidelity, we can simply use the "owl:shameAs" pattern to get them 
on board :-)

No, its just little bugs in the xslt. This cartridge is supposed to make 
a data space comprised of many things:

Artist Descriptions, Events, Genre's etc..

Our problem is that we've built 30+ cartridges and counting, and this 
leads to subtle drops in fidelity when you look at some of the graphs 
with ___domain specificity. Hence my callout for everyone to put heads 
together since we have all the pieces, but are missing the critical 
essence: working together rather than past one another en route to the 
same destination :-)

Yes, but note, how our works, you go to the page via 
<http://ode.openlinksw.com> and you simply view Page Description. We 
start by describing the document which unveils what the document is about.

I noticed that HTML5 [1] has quite an understanding (to my pleasant 
surprise) of this aspect of matters that has generally been overlooked 
in the RDF realm.
