<h1>MMSem Goals</h1>
<ul>
<li>Use SW technologies to make existing multimedia metadata standards interoperable:
<ul>
<li>Leverage and combine existing formats</li>
</ul>
</li>
<li>Show the added value of the SW formal semantics:
<ul>
<li>Practical applications and services that provide extra functionality by using, for example, subsumption reasoning or rule-based approaches</li> <li>Multi-platform applications, adapted to any device that accesses the web</li>
</ul>
</li>
<li>Provide best practices for annotating and using multimedia content on the Web:
<ul>
<li>Practical use cases that identify the users, the type of content and the type of metadata that they want to provide</li>
</ul>
</li>
</ul>

<h1>MMSem Future</h1>
<ul>
<li>Jeff's scenario:
<ul>
<li>
<strong>Possible new Rec Track Working Group on <font color="#333399"><em>Multimedia Annotation Interoperability Framework</em></font></strong>
<li>Goal: To provide an integrated set of vocabulary within a simple extensible framework, so as to improve interoperability of applications related to some key use cases, such as Photo, Music and News
<ul>
<li>Late May 2007: Workshop on Interoperability of Multimedia Annotations</li>
<li>June 2007: Start WG Charter Preparation</li>
<li>October/November 2007: Planned WG starting date</li>
</ul>
</li>
</li>
</ul>
</li>
<li>Raphael's scenario:
<ul>
<li>Multimedia Semantics community is just starting: RDF converters of MM standards are developed in various EU projects</li>
<li><strong>Need to do more research!</strong></li>
<li>Suggest to wait <strong>one more year</strong> before proposing a WG on <strong><font color="#333399"><em>Best Practices for Multimedia Semantics</em></font></strong></li>
