UDDI service registry is of paramount importance when it comes to providing a SOA Governance solution. A service registry stores metadata that is related to the particular asset you have interest in, without actually containing those assets. It is essentially an online directory of services that enables the service providers to advertise their offerings and allowing service consumers to find services that match their criteria. It provides a foundation for the governance and lifecycle management of Business Services. It provides with what is needed to obtain enterprise-wide insight, control and economic leverage of organization’s business and service artifacts. The registry also supports metadata like classifications, categorizations, relationships and properties. These metadata are then used to define taxonomies, describe how service artifacts are related to each other and associate generic as well as object specific characteristics for service artifacts.
Here are some UDDI registries that are widely used in organizations:
1. Systinet Registry (now HP SOA Systinet Registry)
2. Oracle Service Registry : It is a modified version of Systinet Registry. Remodeled according to Oracle needs.
3. Aqualogic Service Registry: Again a modified version of Systinet Registry.
5. TIBCO ActiveMatrix: Again a modified version of Systinet Registry.
