Here are the links to the immutable serializable meta-data classes that 
should be extended:

  
http://avalon.apache.org/merlin/api/org/apache/avalon/composition/data/ContainmentProfile.html
  
http://avalon.apache.org/merlin/api/org/apache/avalon/composition/data/DeploymentProfile.html

http://avalon.apache.org/merlin/api/org/apache/avalon/composition/model/ContainmentModel.html
  
http://avalon.apache.org/merlin/api/org/apache/avalon/composition/model/DeploymentModel.html
