The UDDI specs are available in Word format as well as PDF.
From the http://www.uddi.org/ home page, click on "Specifications", and you get
to choose the format you want.
Pointers to the PDFs are "helpfully" included on the home page as well.
There is also a "Forums" page that takes you to general and technical discussion
groups, which are monitored by the IBM, Microsoft and Ariba people who
presumably chose "urn:uddi-org:api" in the first place.
Strangely, UDDI may actually provide a mechanism for finding out about any
If you look at Appendix I of the Programmers API, on page 60 you will find a
description of the uddi-org:types taxonomy.
One of the values in this taxonomy is "namespace".
What this means is that you can create a UDDI tModel, and categorize it as
representing a namespace.
There are no tModels categorized like this in the UDDI Registry, so, yesterday,

Taking this further, a UDDI tModel has an <overviewDoc><overviewURL> field,
which can be used to point to an RDDL file.
To find out about the namespace "urn:whatever", I could do a UDDI
which would return a list of tModelKeys ( probably with just the one entry ).
For each tModelKey, I could do a <get_tModelDetail>, until I found one
categorized as a namespace,
then follow the <overviewURL> to an RDDL file.

Subject: Seeking lURNed advice on UDDI
I'm beginning to think that UDDI might be real useful.
If you check out the spec-ware (PDF, grrrrrrrrrr) at
it turns out that the UDDI tagset is in a namespace whose
name is "urn:uddi-org:api". This makes me uncomfortable, but
maybe that's just because I don't understand URNs. First off,
how unique is that? It doesn't *look* very unique to a URN
Second, does this mean that you can't use RDDL or even an
ordinary web page to allow the eager-to-learn to discover
some things about the namespace? Or are have URN resolvers
been quietly been springing up while I wasn't looking?
(Neither IE nor Mozilla do anything useful for me with this
particular URI). -Tim
