UDDI Business Registry Closing

by , Comments

Way back in 2001, I had a reader or two ask me about UDDI and a business registry that IBM, Microsoft and others were building upon it, which is now closing.

UDDI is the Universal Description, Discovery & Integration protocol. I mentioned it briefly in this article for SEW members, Navigational Keyword Space Heats Up; Watch Those Claims!, but never got back to doing more about the system as I didn't really see it going anywhere.

Today, I got an email from Microsoft that it was pulling out of the registry:

You are receiving this mail because you have registered as a publisher on the Microsoft node of the UDDI Business Registry (UBR).

The primary goal of the UBR was to prove the interoperability and robustness of the UDDI specifications through a public implementation. This goal was met and far exceeded, and now the UBR is discontinuing its operations. As part of this process the Microsoft UBR node at will be permanently unavailable for all operations beginning January 12, 2006. Data stored in the UBR may be retrieved until January 12, 2006 and used in accordance with the UDDI Business Registry terms of use available at You may find the UDDI Data Export Wizard useful for retrieving your data, and it is available here:
