RE: URIs for quantities and units defined within ISO 80000 and ISO 1000

Hi David L,
 
The rationale given for URIs of quantities and units look good to me. 
 
In the OASIS PLCS TC specs are already under ballot that require URIs for units *now* and so that TC is most likely going to be one of your examples of organizations filling a gap that ISO and other standards bodies are leaving by not recognizing the importance of URIs for the concepts like units that are of critical importance in the engineering disciplines.
 
Cheers,
David

Dear All,

The e-mail below did not elicit any responses. It would be good to have some
opinions.

We can then start to arrange some initial contacts between W3PM, ISO TC12,
and ISO TC184/SC4.

Best regards,
David

>>Dear Atsuko,
>>
>>The Product Modelling "incubator group"
>>(http://www.w3.org/2005/Incubator/w3pm/) within W3C was formed a few months
>>ago. A W3C incubator group investigates technologies with a potential for
>>broad use as part of the infrastructure of the Web.
>>
>>An initial area of work for the group has been quantities and units on the
>>Web. As far as we are aware, this area is not yet covered by any W3C
>>recommendation or ISO standard. The basic concepts are defined in the
>>ISO/IEC 80000 series, ISO 1000, and by the BIPM. However, these standards
>>are not concerned with Web implementation.
>>
>>The W3C Product Modelling group has suggested an approach to Web
>>implementation, but this approach is totally dependent upon an appropriate
>>authoritative body, e.g. ISO, IEC, or BIPM, assigning URIs to basic concepts
>>such as quantity types:
>>- length;
>>- thermodynamic temperature;
>>- mass;
>>- amount of substance;
>>- etc.,
>>and units:
>>- metre;
>>- Kelvin;
>>- kilogram;
>>- mole;
>>- etc..
>>
>>ISO has done preparatory work relevant to this in its URN proposal
>>(http://tools.ietf.org/html/draft-goodwin-iso-urn-03). A next step could be
>>contact between the W3C Product Modelling group, ISO TC184/SC4, and the TCs
>>responsible for the ISO/IEC 80000 series and ISO 1000. The objective of the
>>meeting would be:
>>1) to discuss requirements for referencing quantities and units on the Web;
>>and
>>2) the assignment of URIs for quantities and units to meet these
>>requirements.
>>
>>This area is of interest to ISO TC184/SC4. Most of the existing SC4
>>standards would not use URIs assigned to quantities and units immediately,
>>because the existing approach defined within ISO 10303-41 works. However,
>>future SC4 standards could take advantage of this. There is also
>>considerable expertise on product data on the Web within SC4 which would be
>>valuable.
>>
>>I would be very grateful if you could advise on how to make contact with the
>>TCs responsible for the ISO/IEC 80000 series and ISO 1000, in order to make
>>progress on this matter.
