Anyway, I think we have a nice starting point re. Music Data Space
for getting so RDFizer collaboration going, hopefully, this will
provide a best practices template (re. collaboration) to others

Wherever lastfm.rdfize.com describes a resource with foaf:homepage
property in the http://last.fm namespace, it owl:sameAses to
uriburner's version.
Okay.
I was thinking, do/could you provide metadata about your different
RDFizers (even though they all operate under the same webservice),
perhaps using voiD ?
Nice idea!
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> .
Yep!
Strange we completely overlooked this :-(
As you can see, feedback works !!
(I'm not sure the use of generatorAgent is right here - suggestions?)
maybe:
mvcb:mappingScript
<http://demo.openlinksw.com/DAV/VAD/rdf_mappers/xslt/lastfm2rdf.xsl>
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.
Yep!
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?
Good Linked Data dog-food exercise :-)
