  <h3>System Overview</h3>
  <p>
  This package contains a complete meta info and meta data model for the Avalon 
Component Model.  The package includes services supporting internalization of 
model instances from XML including type defintions, deployment profiles and 
default criteria for a component.
  </p>
  <p>Main components of the framework include:
    <ul>
      <li>Type structures for the Avalon Component Model.</li>
      <li>Profile strucure supporting declaration of type instantiation 
criteria.</li>
      <li>Type and Profile validation framework.</li>
    </ul>
  </p>
  
  <h3>Package Structure (UML)</h3>
  <p><img src="meta.gif" border="0"></p>
  
  <h3>Deployment Model</h3>
  Components types deployed under this model must be declared as formal 
component types using a &lt;classname&gt;.xinfo descriptor. Components types 
may also be deployed with default profile criteria 
  and configuration information.</p>
  
  <ul>
    <li>&lt;classname&gt;.xinfo
      <ul>
        <li>General component type information.</li>
        <li>Context constraints.</li>
        <li>Dependecies.</li>
        <li>Service declarations.</li>
      </ul>
    </li>
    <li>&lt;classname&gt;.xprofile
      <ul>
        <li>Configuration/parameter profiles.</li>
        <li>Context creation directives.</li>
      </ul>
    </li>
    <li>&lt;classname&gt;.xconfig
      <ul>
        <li>Default configuration/parameter.</li>
        <li>Default context directives.</li>
      </ul>
    </li>
  </ul>

Service Management Framework</a></li>
  </ul>
  
  <h3>Demonstration</h3>
  Merlin is a service management framework that demonstration of the deployment 
of a complex hierachy of containers and components with multiple dependecies 
(including cross-container dependencies) and dependecy conflicts.  The 
framework uses the Avalon Meta Model is the underying infrastructure for type 
and profile management.
  
  <h3>Current Status</h3>
  <p>
  The implementation provides full support for type and profile creation.  Work 
is ongoing with result to increased functionality with respect to complex 
profile creation and default information management.
