I am writing for cio.com again and thought I'd go back down the SOA track. This will be in parallel to my BizTalk specific posts here, but there will be a lot of overlap. The UDDI series I am just starting will mostly be based on the UDDI v3 that is part of BizTalk Server 2009. The first of the cio.com articles can be found here: http://advice.cio.com/dan_rosanova/why_uddi_is_important
Future articles will elaborate on the points presented in the article above.
