All resource identifiers defined by this RDF dump are dereferencable. <!--, and support content negotiation. 
46
Using the <i>Accept: application/rdf+xml</i> header field, a RDF/XML representation of the resource is sent back.
47
Otherwise, a HTML representation, done using <a href="http://zitgist.com/">Zitgist</a>,
48
is sent back.

109
<a href="http://dbtune.org/magnatune/all/artist">http://dbtune.org/magnatune/all/artist</a>)
110
and then look for <a href="http://purl.org/ontology/mo/MusicArtist">http://purl.org/ontology/mo/MusicArtist</a>. You will then see

The service also exposes a <a href="http://www.w3.org/TR/rdf-sparql-query/">SPARQL</a> end-point, available
117
at <a href="http://dbtune.org/magnatune/sparql/">http://dbtune.org/magnatune/sparql/</a>. There is also a small

<p>
123
The RDF dump is <a href="http://moustaki.org/resources/magnatune_main.rdf">available for download</a>. 
124
The package holds the raw Jamendo data converted to RDF (available under the same license than the raw Jamendo
125
data itself), as well as the links towards Geonames and the links towards Musicbrainz. These links are available
126
under a <a href="http://creativecommons.org/licenses/by-nc-sa/3.0/">Creative Commons Attribution-Noncommercial-Share Alike 3.0 License</a> (subject to
127
change, ask me).

<h2><a name="tools" id="tools"></a>5. Tools</h2>

The RDF dump was created using <a href="http://sites.wiwiss.fu-berlin.de/suhl/bizer/d2r-server/">D2R server</a>.

<p>
136
The tool handling dereferencable identifiers is available <a href="http://moustaki.org/urispace/">here</a>. It is a small HTTP server implementing content
137
negotiation. The behavior of the server is specified by a declarative mapping from resource identifiers to the location of
138
their representation.
