Subject: Re: taxonomy discussion at OASIS


This subject has been tackled by a few bold individuals.  The idea I put
forth was to allow multiple classification schemes within a specified
information model.  The RA can allow semantic references suggested by
the SO or Data Steward to be referenced from the repository item.  An
Example which may work is a fictional "Skateboard" company.   They may
have a regrep item which contains all the information about their
business including their products.  The document instance could appear
similar to this:

 	<classification  Scheme="NAICS"
	<classification  Scheme="UNSPSC"
	<classification  Scheme="UPC-FRANCAIS" value="10764001051">Board du

This model would allow for efficient retrieval of items by writing a
parser handler that can iterate through the child elements of each
<item> element seeking for a attribute value equivalent to a recognized
Scheme.  A contextual query can also seek for a match on an attribute
value of a recognized scheme and return a hash of positive matches in a
business case where a user was intending to locate manufacturer's of a
specific item.  Becuase there can be multiple schemes employed for each
product or item,  there are no inherent limitations (hence scalability,

This is also not limited to items for manufacture.  

I believe that the OASIS, ebXML and UDDI registry models should contain
information models which allow  multiple classification schemes.  Those
who wish to re-invent the wheel are free to do so and those who use
existing standards are also accomodated.
