Alternatively, one could treat the taxonomy not as a model, (these terms
'are an image of' reality) but as a system of differentia (these
criteria map reality into this set of terms). The question is then not
whether one system was more truthlike than another, but whether the
differentia are adequate for our purposes.    (01)

This is not to say that a model and set of differentia are mutually
exclusive - 'ideally' they should give the same system - but using one
does not require that one construct the other.    (02)

A consequential question - are ontologies (in the computing sense)
defined only by models, or can they be defined by differentia, and what
would this mean for interoperability?    (03)
