we
would like to propose to rename the property "definition editor" into
"term editor". We believe that (i) this would better reflect the fact
that the definition editor is the person editing the definition, but
also the label, example of usages etc (ii) this would still be inline
with the purpose of that annotation property, which is indicating a
point of contact/reference should any question about the term arise.
