Purpose
Each data manager have configuration values that can be used as identifiers, or attributes that indicate their functions. This enhancement is to provide the mechanism to configure these values at deployment time, and expose these values through web services.
Requirements
Identifier of a data manager
The current implementation (as of i10) uses the Axis2 service group name and hostname together to uniquely identify a data manager.
CMDBf an important use case for data managers. That is, a data manager can be an MDR or a federating CMDB. The CMDBf specification has the notion of a "MDR ID", which is a URI that can uniquely identify a MDR. The MDR ID is also used to locate configuration items and relationships. The goal is the consolidate the approach for identifying an MDR and a data manager so that we don't need multiple ways to identify a data manager.
Descriptions of the data manager
There are attributes about a data manager that provide information about the services it provides. These values can be displayed by the UI or used programmatically by a client application. These values include the display name, description, and other application specific name-value pairs. One requirement about these values is that they may be locale specific.
SOAP version of web services
Axis2 supports web services using SOAP 1.1 or 1.2. While it is possible to deduce the SOAP version by getting the whole WSDL from the server, it is more efficient to get the SOAP version from the server without transfering the whole WSDL to the client.
Use Cases
2.1.11 Use Case: Configure an MDR
