Taxonomy Schemas

Hi,

While investigating the issue of creating a schema for our taxonomies I 
spoke to Mavis Cournane of the OASIS UBL Naming and Design Rules sub 
committee. They have already solved this problem in a very well thought 
out manner. Please find attached the UBL code list discussion document 
which lays out very eloquently both the alternatives and the schema 
architecture of choice, as well as an example of its usage for defining 
ISO 3166 country codes.

The UBL schema for taxonomies incorporates the list of valid codes as an 
enumeration within the schema itself. This means that the act of parsing 
  automatically validates any codes. I would strongly recommend adopting 
this approach.

For standard codes such as language and country codes I recommend that 
we look at sharing the UBL schemas.

We would need to create individual schemas for the following taxonomies:

Service offerings
Content domains

Which would be maintained by Lisa.

I am indebted to Mavis for her kind advice and guidance.

Regards,

Andrzej Zydron
