From DeveloperWorks, Hello World: WebSphere Service Registry and Repository

Manage, govern, and share services across your organization by
using WebSphere Service Registry and Repository. Follow the hands-on
exercises to learn how to navigate the Web interface to publish, find, reuse, and update services.

When ever I get my hands on a new product, I like to go through the “Hello World” example in order to familarize myself with the concept and constructs. In this article, you’ll get familar with IBM’s new SOA repository product: WebSphere Service Registry and Repository. (WSRR)

In a nutshell, WSRR allows you to answer a question that (will one day) plague your SOA: “Who the heck is using my service?”. It’s a product centered around SOA governance. It allows you to browse the relationship between your service, your consumed services and the services consuming you (in addition to a whole lot of other neat stuff).
