The CentraSite registry supports the JAXR information model. Physically, the registry resides in a single XML database that can be accessed using XQuery, UDDI, or JAXR-based client APIs.

A JAXR-based registry is built around a generic, but extensible object called a RegistryObject. The RegistryObject class defines a minimal set of metadata and provides methods that enable an object to be classified and associated with other objects in the registry.

Although the metadata that RegistryObject specifies is very minimal (Name, Description, and Key), it can be dynamically extended to incorporate additional metadata. By extending the RegistryObject, one can model and catalog virtually any type of artifact in an SOA environment.

The object types that make up the CentraSite registry are all extensions of the basic JAXR RegistryObject class.
