UDDI does not provide an integrated reporsitory which means that it 
lacks " control, and standard ways of storing and retrieving them".
So for example it does not provide end-to-end lifecycle management of 
these artefacts. This includes publish, update, validation, approval, 
deprecation, undeprecation, cataloging, versioning, access control and 
event notification  of these artefacts. What it provides is a sub-set of 
said capabilities for the metadata for these artifacts.

Indeed there are plenty of content management solutions available to 
manage these things but they do not do so in a standard way facilitating 
federation and interop across these content management solutions.

Also you find the following useful:

ebXML Registry has an approved TN on publishing Web Services in an ebXML 
Registry. We are in the process of updating that document for version 3.

[11] Registering Web Services in an ebXML Registry
http://www.oasis-open.org/committees/download.php/11907/regrep-webservices-tn-10.pdf

I am also proposing that we define a WS Profile for ebXML Registry 3.0.

Our specs provide an ability for any spec compliant ebXML Registry to 
organically federate with any other spec compliant ebXML Registry.

Please see:

No it does not. This feature is optional in UDDI 3.0. We do however 
support the ebXML Registry 3.0 Content-Based Event Notification feature 
which is much more powerful than the UDDI v3 subscription API because it 
allows domain/application specific queries to be used to subscribe to 
precisely those event of interest to a party.

For example with the ebXML Registry Content-Based Event Notification 
feature, you can subscribe to any GIF image being submitted that is in 
Color and has a specified minimum dimension and is classified by 
Geography of Istanbul.

We made the assumptions that customers do not care what API is used 
under the hood as long as it is based on an open standard and meets 
their needs.

Thanks again for your valuable comments.
