Subject: Re: [ubl] Commodity code (was: Re: [ubl] Minutes of Pacific UBL TCcall 5|6 May 2008)
[roberto@javest.com:] | The hierarchy is important to group commodities, but it is fully | listed to let the user select a commodity in a very precise way or | more generally through its upper group. I understand; the system strongly resembles the one used in the U.S. to code employment categories. But you end up with so many codes that I wonder what advantage is gained by providing the code list. At some point you end up with the equivalent of a code list to check the validity of integers; you could do it, but there are easier ways to check whether something is an integer than providing an enumeration. | The taxonomy change every year, mainly to include new commodities | and rarely to add a new group. The code list version MUST be | specified when a value is used (NC 2008) This implies pretty strongly that we would have to issue an update every year. As we're not organizationally constituted to stay in existence forever, I don't think that this is something we should be committing to do. I believe that it would be much better to persuade the issuing authority to provide their annual update in genericode. Jon
