Sun Web Services Registry

As part of the Sun efforts around SOA:

Sun Microsystems has announced the development of a Web Services Registry and Repository for building Service-Oriented Architectures (SOA). The Sun Service Registry "enables service oriented architectures by providing centralized access to discovery, use, and reuse of web services as well as secure, federated information management. By offering a unique single-registry solution that supports both UDDI v3 and ebXML Registry 3.0 standards, Sun's Service Registry enables customers to publish, manage, govern, discover and reuse services within a broad range of applications."
