<ul CLASS="UnorderedList">
<li CLASS="Item">An <b>activity</b> is unit of execution.
<ul CLASS="UnorderedList">
<li CLASS="Item">An activity contains a set of contracts (i.e., the actity parameters)</li>
<li CLASS="Item">A contract has a type, a mode (input, output, intput/output), a default value (depends on the type)</li>
</ul>
</li>
<li CLASS="Item">A <b>factory component</b> (FC) is an activity.</li>
<ul CLASS="UnorderedList">
<li CLASS="Item">A FC contains a set of viewpoints. A viewpoint defines a type of generation data (e.g., domain, mapping, pattern).</li>
<li CLASS="Item">A FC contains an <b>orchestration</b>.
<ul CLASS="UnorderedList">
<li CLASS="Item">An orchestration contains a context, with the same characteristics than a contract</li>
<li CLASS="Item">An orchestration contains an ordered set of activity invocations (to factory component or task)</li>
<li CLASS="Item">An activity invocation provides values to the invoked activity: from 1) local values to the invocation, 2) the orchestration context, 3) the factory component contracts</li>
<li CLASS="Item">A factory component hierarchy requires at least a task call to execute productively something</li>
</ul>
</li>
</ul>
</li>
<li CLASS="Item">A <b>task</b> is an activity. It is linked to a Java class that implements the expected behavior.</li>
<li CLASS="Item">A <b>domain viewpoint</b> is a viewpoint.
<ul CLASS="UnorderedList">
<li CLASS="Item">A domain viewpoint declares a domain with a URI (platform:/plugin/...)</li>
<li CLASS="Item">The domain is used in activity invocations through a URI type that references the domain</li>
</ul>
</li>
<li CLASS="Item">A <b>pattern viewpoint</b> is a viewpoint.
<ul CLASS="UnorderedList">
<li CLASS="Item">A pattern viewpoint contains pattern libraries which contains pattern libraries and patterns</li>
<li CLASS="Item">A pattern has 1) a specification, where are declared the pattern parameters, 2) an implementation that contains methods</li>
<li CLASS="Item">Pattern methods are in written in a language, for instance Jet for model-to-text transformation</li>
<li CLASS="Item">Pattern can inherit from a super-pattern, can call patterns with a context injection or not</li>
</ul>
