From DeveloperWorks, Create classification taxonomies programmatically in IBM WebSphere Service Registry and Repository

By creating classification taxonomies in IBM WebSphere Service Registry
and Repository, you can flexibly catalog and organize services and your metadata,
enabling effective governance. This article illustrates a mechanism for
uploading classification taxonomies into the WebSphere Service Registry
and Repository using an XML-based interface, which can also be extended as an
integration mechanism for synchronizing classification taxonomies to WebSphere
Service Registry and Repository from other external systems. Find out how to load the
classification taxonomies into WebSphere Service Registry and
Repository using the Java Management Extensions (JMX) management APIs provided by WebSphere Service
Registry and Repository.

Articles about WSRR seem to be few and far between, so here is one that deals with classification taxonomies, something I know nothing about.
