Generic Functional Requirements
- Must support robust and timely data synchronization from the source IDMS, either via notification from the IDMS or extraction of state from the IDMS
- Should support message queues both for notifying external systems of changes and for receiving notification of changes from external systems
Standards Support and Integration Considerations
Support of SPML is desirable, however the number of IDMSs, Provisioning Engines, and SPs supporting SPML is low.
There are no standards for extracting data from the IDMS, which will likely require significant custom integration effort.
Key Design Considerations
See the Data Integration section for general principles that apply to this section as well.
The design of the source IDMS will likely influence how integration with the provisioning engine is designed. IDMSs capable of supporting change notification will likely push events to the provisioning engine, while those that do not will likely require the provisioning engine to have access to the IDMS' database.
Technical Solutions
A provisioning engine can be thought of a message switch, which accepts messages or extracts information from an IDMS and sends messages to SPs via real time notification, message queues, or batch extracts.
