|Microsoft Identity Integration Server 2003 Developer Reference|
Microsoft Identity Integration Server 2003 has a flexible synchronization rules engine that allows you to process identity data between your connected data sources and the metadirectory according to your business rules. Your business rules are expressed as synchronization rules in Microsoft Identity Integration Server 2003 either as declarative rules or through rules extensions.
Declarative rules are synchronization rules that are configured through the Identity Manager of Microsoft Identity Integration Server 2003. For business rules that are beyond declarative rules, you can use a rules extension to express otherwise complex logic in a well-structured form.
Both declarative rules and rules extensions coexist to provide you with the flexibility of choosing the appropriate method for a given scenario. The following list shows some of the rules that can be expressed in rules extensions:
A rules extension is a .NET Framework assembly implemented in the form of a dynamic link library (.dll) file. You can create a rules extension using any programming language and compiler that creates a .NET Framework assembly. For more information, see Creating Rules Extensions.
The following types of rules extensions are supported by Microsoft Identity Integration Server 2003.
|Management agent||Used on data that flows between the connector space and the metaverse, such as data transformations, join rules, and deprovisioning. Each management agent can have only one rules extension.|
|Metaverse||Used on data that flows between the metaverse and connector space in response to a change in the metaverse, such as when an attribute value changes or a link is added or removed from a metaverse object. For example, you can use a metaverse rules extension to create provisioning rules to ensure that all the connected system objects contain the unified identity data that is stored in the metaverse. You can have only one metaverse rules extension.|
Rules extensions are called when identity data is processed. For more information, see How Rules Extensions Are Called. To see how the synchronization rules map to the rules extension methods, see Synchronization Rules Mapped to Rules Extension Methods.
Objects in the connector space and metaverse are created from the following classes.
|CSEntry||Connector Space Object|
Most of the classes in the Microsoft.MetadirectoryServices namespace are related to these two objects.
