Component and Application Descriptions

• The Component Static Information is an XML document that contains basic type information about the component and all the details of its execution environment for each host on which it has been deployed. This contains necessary and sufficient information to launch the component it describes. This information is provided by the component developer.

  This information can be embedded in the Application Static Information or can be obtained through a call to a simple directory service, called the Component Browser. This is a repository of Component Static Information and allows a user to browse components by type name or to search for components by other attributes such as the port types they support.
