  <h1>Multimedia Metadata Interoperability</h1>
  <ul>
    <li><strong>Use SW technologies to make existing multimedia metadata standards interoperable</strong>:
      <ul>
	  <li>Leverage and combine existing formats and show the added value of the SW formal semantics,</li>
        <li>Provide best practices for annotating and using multimedia content on the Web</li>
      </ul>
    </li>
    <li><strong>Photo Use Case</strong>:

  <h1>Multimedia Metadata Interoperability (cont)</h1>
  <ul>
    <li><strong>Music Use Case</strong>:
      <ul>
        <li>ID3 Tags + low-level features extraction + lastFM recommendations + FOAF profiles + ...</li>
        <li>Auto-construction of playlist (similar bit rate), Personalization, Browsing music store</li>

      </ul>
    </li>
    <li><strong>Personomy Manager Use Case</strong>:
      <ul>
        <li>Multiple tagging platforms for various media:<br/>
           Flickr, YouTube, DailyMotion, Myspace, Last.fm, Del.icio.us, etc.</li>
        <li>Extraction of personals tags, SKOS representation</li>
        <li>Search, annotate cross-platforms</li>
