I agree that there is a sense of 'term' (meaning, roughly, 'entity')
in which your definition works; but it is very much a secondary
sense, so that its use is likely to be misleading, since the primary
sense is linguistic (a term is a word); perhaps we can use 'entity'
(this has the perhaps trivial advantage that it comes from the same
Greek root as 'ontology'). (02)
This does not mean 'term' is not relevant to our purposes. An
ontology (in my view) consists of terms (and relational expressions),
which represent entities (and the relations between them). (03)

Most of them are in the OBO Foundry (http://obofoundry.org); by far
the most influential (50K users) is the Gene Ontology. These are not
ontologies which represent concepts (or meanings or terms); rather
they represent entities in biological reality.
