It does not. The ebRS spec defines a generic extensibility architecture for any domain/application specific Content Cataloging Service. This generic ability is then specialized as canonical specs for domain specific profiles. The WSDL cataloging is being defined in the Web Services Profile for ebXML Registry (draft stages) and being simultaneously prototyped in freebXML Registry open source project. > > Or is this a non-standard value-added feature of a particular > implementation? The generic Content Cataloging feature is a standard feature of ebXML Registry 3.0. The WSDL Cataloger is a standard feature of the Web Services Profile (draft). The idea is that the registry remains generic and extensible while domain specific profile such as the Web Services Profile define normatively how to extend or restrict ebXML Registry features for that profile. The result is that the core ebXML Registry specs do not get burdened with the kitchen sink and refrigerator and specific verticals and domains can use the ebXML Registry in an interoperable manner. > > Or is it in a "WS profile for ebXML Registry"; please provide a link > to it? > It is in the WS Profile for ebXML Registry. The latest draft may be found at: http://lists.oasis-open.org/archives/regrep/200506/zip00000.zip It is quite raw in its current state and is missing several key details. I can post updates to this thread as newer version emerge. If anyone has thoughts on specific features they would like to see in the Web Services Profile for ebXML Registry please share. ebXML Registry is a community driven standard and your input can make a direct and immediate impact.
