Subject: 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
