Units of Measure #132

Closed philarcher closed 1 month ago

philarcher commented 1 month ago

Product dimensions and other units of measure should make use of UN/ECE Recommendation 20. See http://www.unece.org/fileadmin/DAM/cefact/recommendations/rec20/rec20_rev3_Annex3e.pdf.

This is used by schema.org and GS1 Web Voc. See, for example, https://ref.gs1.org/voc/unitCode.

In practice, awkward and counter-intuitive as it may be, uppercase GRM is used rather than the more natural 'g', etc.
