Re: ontology for units of measurement and/or physical quantities

Hi Robert,

N-ary relations [1] seems like a straightforward way of representing
values with units, there's an example in the Primer [2] (here as
Turtle syntax, a bit clearer):

exproduct:item10245   exterms:weight  [
                 rdf:value        "2.4"^^xsd:decimal ;
                 exterms:units    exunits:kilograms .
]

Cheers,
Danny.
