This service provides a live <a href="http://blog.dbtune.org/post/2008/01/11/Your-AudioScrobble-data-as-linked-data">RDF |
| 26 |
representation</a> of your last 10 tracks submitted to
|
| 27 |
<a href="http://www.audioscrobbler.net/">AudioScrobbler/Last.fm</a>. |
| 28 |
There are |
| 29 |
many AudioScrobbler clients for a wide range of media players. |
| 30 |
|
| 31 |
It now also provides you with <a href="http://blog.dbtune.org/post/2008/01/22/Pushing-your-LastFM-friends-in-the-FOAF-O-Sphere">the list of your friends (using their URI on this service, allowing to access |
| 32 |
their friends and scrobbles)</a>.

This representations is designed using the <a href="http://musicontology.com/"> |
| 38 |
Music Ontology</a>, <a href="http://xmlns.com/foaf/0.1/">FOAF</a> and |
| 39 |
a small <a href="#scrobbleonto">AudioScrobble ontology</a>. Moreover, |
| 40 |
it is interlinked with corresponding dereferencable <a href="http://en.wikipedia.org/wiki/Uniform_Resource_Identifier">URIs</a> |
| 41 |
in the <a href="http://musicbrainz.org/">Musicbrainz repository</a> (see |

<h2><a name="use" id="use"></a>2. Using this service</h2> |
| 55 |
<p>
|
| 56 |
Just get the following URI: |
| 57 |
<pre>
|
| 58 |
http://dbtune.org/last-fm/<username> |
| 59 |
</pre>
|
| 60 |
Where <username> is your <a href="http://last.fm/">Last.fm</a> username. |
| 61 |
</p>
|
| 62 |
<p>
|
| 63 |
Try to load this URI in the <a href="http://www.w3.org/2005/ajar/tab">Tabulator</a> |
| 64 |
to jump to the Musicbrainz |
| 65 |
description of the artists, tracks, albums you listened to, to plot your last |
| 66 |
scrobble on the <a href="http://simile.mit.edu/timeline/">Simile Timeline</a>, etc. |
| 67 |
</p>
|
| 68 |
<p>
|
| 69 |
You can also add this information to your <a href="http://xmlns.com/foaf/0.1/">FOAF profile</a> by adding the following line in it: |
| 70 |
<pre>
|
| 71 |
<my URI> owl:sameAs <http://dbtune.org/last-fm/<username> |
| 72 |
</pre>
|

<h2><a name="scrobbleonto" id="scrobbleonto"></a>3. AudioScrobble ontology</h2> |
| 76 |
<p>
|
| 77 |
For the purpose of representing AudioScrobble events in RDF, we designed |
| 78 |
a really small <a href="http://purl.org/ontology/last-fm/">Scrobble |
| 79 |
ontology</a>, heavily based on the <a href="http://purl.org/NET/c4dm/event.owl#">Event ontology</a>. Basically, it just defines a |
| 80 |
<a href="http://purl.org/ontology/last-fm/ScrobbleEvent"><b>Scrobble</b> event</a> |
| 81 |
as being a sub-concept of the <a href="http://purl.org/NET/c4dm/event.owl#Event"><b>Event</b> one</a>, and a <a href="http://purl.org/ontology/last-fm/user"><b>user</b> |
| 82 |
property</a> as being a sub-property of the <a href="http://purl.org/NET/c4dm/event.owl#agent"><b>agent</b> one</a> |
| 83 |

<p>

As usual, <a href="http://motools.svn.sourceforge.net/viewvc/motools/lastfm/">all the code running this service</a> |
| 88 |
is open source and based |
| 89 |
on <a href="http://www.swi-prolog.org">SWI-Prolog</a> |
