� «packaging» language
� Offered functionality (Server role)interfaces providedevents emitted
� Configuration attributes
� Define a component in terms of...
� Dependencies (Client role)distant interfaces requiredevents consumed

Idl2
� An IDL2 interface
� Defining interface between component and container
� Middleware, Framework independent
Container
� Container code
� Provides the glue between application and infrastructure

82CORBA Component Model (CCM)
� Container handles,
� Component interconnection
� Event issues
� Config / packaging issues
� Other functions
� Local IDL (local service ie no IOR)
� Component is isolated from the underlying architecture (framework).
� This is a standard & formal way of creating wrappers.
