Wherever lastfm.rdfize.com describes a resource with foaf:homepage  
property in the http://last.fm namespace, it owl:sameAses to uriburner's  
version.

I was thinking, do/could you provide metadata about your different  
RDFizers (even though they all operate under the same webservice), perhaps  
using voiD ?

You could do something like:

:UriBurner a voiD:Dataset ;
	void:subset :LastFmRDFizer ;
	foaf:homepage <http://linkeddata.uriburner.com/> .

:LastFMRDFizer void:uriRegexPattern "(http://.*last.fm/.*) |  
(http://.*lastfm.*/.*)" ;
	void:exampleResource  
<http://linkeddata.uriburner.com/about/rdf/http://www.last.fm/user/winningsperm/events>  
;
	mvcb:generatorAgent  
<http://demo.openlinksw.com/DAV/VAD/rdf_mappers/xslt/lastfm2rdf.xsl> .


(I'm not sure the use of generatorAgent is right here - suggestions?)


If such (meta)data were provided, it would be possible  to have a service  
where I could paste in a web page url, and find out where I could get an  
RDFized version of the data in it.

What do you and others think? It is already hard to know/remember/find all  
of what is available - Kingsley, you said, OpenLink alone has, was it 30?  
cartridges for rdfizing particular web sites ... And here we have  at  
least 4 services RDFizing various parts of last.fm as linked data. It  
would be really nice if this stuff was not just findable and interlinked  
(with owl:sameAs etc) at the RDFized resource level, but also at the  
dataset level.

I think providing enough metadata to be usefully findable is especially  
important for 3rd party dynamically RDFized datasets. If I am a developer  
that wants some RDF of last.fm data, and I don't see it on last.fm, how  
can I know if there is any elsewhere?
