WMO Common Code Table C-15 (Physical quantities) and QUDT unit of measurement

New common code table C-15 (Physical quantities) is under development in the WMO Manual on Codes.  This is to be served as online registory http://codes.wmo.int/common/c-15.  In my understanding the primary motivation at the moment is to provide semantic description of quantities used in the Aviation XML.

The table is of course a list of entries, each describes a quantity, for example "airTemperature" http://codes.wmo.int/common/c-15/me/airTemperature.  Looking at the table, there is a field "generalization" with value "ThermodynamicTemperature" that links to http://qudt.org/vocab/quantity#ThermodynamicTemperature.

This is a link to QUDT.  The top page describes only SI and CGS systems, but there seems to be care for other conventional units.
