Re: [uddi-dev] RE: Representing Hierarchical Value Sets (for example foruddi:uddi.org:categorization:types)

[Tom Bellwood <bellwood@us.ibm.com>]

Pranav,

You are correct.  There is currently no spec. defined mechanism for
defining the structure of a value set, nor are there any APIs defined for
saving and querying the content of a value set.   Maintaining this data has
been deemed beyond the scope of the UDDI registry up through the V3
specification, defering to the referential nature of UDDI.

The topic you raise has, however, been the topic of discussion for sometime
now in the UDDI TC.   Work in this area will be considered as a candidate
item in V4.

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.
