Dear all,

The lists of present, regrets, chair, scribe are not written. Could you 
please amend these minutes in order to state who were on the call (I 
have sent regrets)?

Regarding the discussion on iTunes and QT:

At the time of the W3C Multimedia Semantics XG, we performed a 
conversion from the iTunes XML library format to RDF for the Music Use 
Case [1].

For example, given the iTunes xml for a song:
   <dict>
     <key>Track ID</key><integer>412</integer>
     <key>Name</key><string>Prelude</string>
     <key>Artist</key><string>John Legend</string>
     <key>Album</key><string>Get Lifted</string>
     <key>Genre</key><string>R&#38;B</string>
     <key>Kind</key><string>AAC audio file</string>
     <key>Size</key><integer>1107320</integer>
     <key>Total Time</key><integer>44070</integer>
     <key>Track Number</key><integer>1</integer>
     <key>Track Count</key><integer>14</integer>
     <key>Year</key><integer>2004</integer>
     <key>Date Modified</key><date>2005-11-08T14:19:01Z</date>
     <key>Date Added</key><date>2005-10-15T13:07:20Z</date>
     <key>Bit Rate</key><integer>128</integer>
     <key>Sample Rate</key><integer>44100</integer>
     <key>Play Count</key><integer>4</integer>
     <key>Play Date</key><integer>3231084877</integer>
     <key>Play Date UTC</key><date>2006-05-21T17:34:37Z</date>
     <key>Artwork Count</key><integer>1</integer>
     <key>Persistent ID</key><string>BF7260692B49B7C1</string>
     <key>Track Type</key><string>File</string>
     <key>File Type</key><integer>1295270176</integer>
     <key>File Creator</key><integer>1752133483</integer>
 
<key>Location</key><string>file://localhost/Archive/Music/John%20Legend/Get%20Lifted/01%20Prelude.m4a</string>
     <key>File Folder Count</key><integer>4</integer>
     <key>Library Folder Count</key><integer>1</integer>
   </dict>

The rdf would be:

<itunes:Song rdf:about="&itunes;Song3"
     itunes:Album="Get Lifted"
     itunes:Artist="John Legend"
     itunes:Artwork_Count="1"
     itunes:Bit_Rate="128"

     itunes:Date_Modified="2005-11-08T14:19:09Z"
     itunes:File_Creator="1752133483"
     itunes:File_Folder_Count="4"
     itunes:File_Type="1295270176"
     itunes:Genre="R&amp;B"
     itunes:Kind="AAC audio file"
     itunes:Library_Folder_Count="1"
     itunes:Name="Number One"
     itunes:Persistent_ID="BF7260692B49B7C6"
     itunes:Play_Count="5"
     itunes:Play_Date="3257674326"
     itunes:Play_Date_UTC="2007-03-25T11:32:06Z"
     itunes:Sample_Rate="44100"
     itunes:Size="3573035"
     itunes:Total_Time="198134"
     itunes:Track_Count="14"
     itunes:Track_ID="417"
     itunes:Track_Number="6"
     itunes:Track_Type="File"
     itunes:Year="2004">
 
<itunes:Location>file://localhost/Archive/Music/John%20Legend/Get%20Lifted/06%20Number%20One.m4a</itunes:Location>
</itunes:Song>
