Getting serious about UDDI, Step 1
If you search uddi.microsoft.com for "Services" by the "RSS - Version 2.0" tModel, there's exactly one entry at this time. Mine. Fix that.
Using the UDDI SDK 2.0 (part of the Platform SDK), the following snippet is a simple console app that lists all weblogs registered with the RSS 2.0 tModel in the Microsoft UDDI registry [thanks to Karsten Januszewski for his doc, tModel bootstrap and code]. The advantage? If aggregators were able to remember my service key instead or in addition to my absolute access point (right now http://radio.weblogs.com/0108971/rss.xml), I could move the RSS feed around to any arbitrary locations without any pain and clients would still be able to find it using a simple lookup into the registry. And the infrastructure is all there. No future thing.
