RE: Representing Hierarchical Value Sets (for example for uddi:uddi.org:categorization:types)

["Pranav Parekh" <pparekh@digev.com>]

Thanks for the response Sam.


Some follow-up comments and questions..

In my original question, when I mentioned that I was unable to find any
details in the spec. as to how the hierarchical value set is
represented.. I meant to say I was unable to find the XML representation
of the hierarchical value set.

Also, since there are no APIs for users of the registry to retrieve the
hierarchical value set (that a category scheme or identifier scheme is
bound to have), any vendor who thinks it is important or necessary to
expose this functionality for end users will have a custom
implementation.  In light of that, is there a preferred approach that
the UDDI committee has recommended which might become part of a future
specification?

Thanks,
- Pranav

The complete hierarchy of the value set 
uddi:uddi.org:categorization:types tModel is detailed in the spec 
section 11.1.1.4:

http://uddi.org/pubs/uddi_v3.htm#UDDITypes

There is no API for users of the registry to retrieve this value set.

In general, in UDDIv3, there are APIs (such as the get_allValidValues 
you mentioned) to allow a *registry* (rather than the users of the 
registry) to retrieve valid values of a value set from a value set 
provider.

The API set was created to allow a registry implementation to cache the 
valid values for spell-check type of validation, rather than for end 
users to retrieve the values and the structure (such as hierarchy) of a 
value set.
