Re: last.fm events RDFizing

Hi Kingsley,

How does this work under the hood? uriburner recognises the last.fm  
___domain, and parses the URI to understand how to call the last.fm web  
service api? Then it passes the result to the stylesheet ? Normally  
uriburner would parse the microformats erdf and rdfa in the page right ?  
But if the uriburner sponger has a special knowledge of the ___domain name,  
it will use other means to generate the RDF ?

What coverage of last.fm URIs are understood ?

http://linkeddata.uriburner.com/about/html/last.fm/user/winningsperm/events  
doesn't seem to come up with much, and I was hoping for an equivalent to:

http://lastfm.rdfize.com/?username=winningsperm

Yes, if I had known your uriburner service had a last.fm API xslt, and I  
had been able to get a list of events that a user planned to attend (is  
this possible?), I would definitely not have reinvented the wheel ...   
However, now that it is up there, so long as Tom Heath is happy to host it  
at rdfize.com (thanks Tom), I think it is good to keep it. It is not a bad  
thing to have more than one dataset rdfizing the same ___domain - especially  
if they link to each other.

Some differences I have spotted between uriburner and lastfm.rdfize.com:

Your mapping uses Vevent as the rdf:type for the event resources - could  
you also type it with mo:Performance, or would that have some strange  
implications?

I chose mo:performer where your conversion uses foaf:topic

There is also a machine-tag property for the events in last.fm's xml - I  
minted http://open.vocab.org/terms/machineTag for it.
I have a vague feeling this could be interesting, and provide a point of  
linkage into, eg: flickr. Can anyone tell me how I can link into a linked  
data coversion of flickr or something, using machine tags ?
