The UDDI Spec TC recently discussed a TN for understanding Key Partitions. I had submitted some comments to the TC. In discussion these comments, we talked about the concept of "well-known" taxonomies (with well-known tModelKeys).

It turns out that uddi.org has a place to register such well-known tModels.

Perhaps standards groups should be reminded and encouraged to use it.

For example, WS-PolicyAttachment defines tModelKey="uddi:schemas.xmlsoap.org:remotepolicyreference:2003_03"

I don't think W3C has addressed how it might handle UDDI keys that they might produce. For example, the tModelKey above comes from the earlier versions of WS-PolicyAttachment before a W3C WG was formed.

Like namespaces, where WSDL 1.1 used http://schemas.xmlsoap.org/wsdl/, but WSDL 2.0 uses http://www.w3.org/2006/01/wsdl, W3C may want to define their own UDDI keys (e.g., uddi:w3.org:...) and then publish them at uddi.org. Or better yet, stand up a UDDI registry at W3C or IANA to register such tModels.

While I'm on the topic, just like RDDL is used as a "namespace document", RDDL could (SHOULD) also be used as a "taxonomy document". The overviewURL of the tModel would point to a RDDL document (as I have mentioned before).
