Dear Nicola, (01)
I agree. (02)
Perhaps the best way to start would be for one of the NIST experts, perhaps
Ed Barkmeyer, to propose an initial ontology of a few high level objects and
relationships taken from clause 1 of "International vocabulary of metrology
— Basic and general concepts and associated terms (VIM)"
(http://www.bipm.org/utils/common/documents/jcgm/JCGM_200_2008.pdf). This
could then be reviewed and extended. (03)
Best regards,
David (04)
