[Ontology-editors] Precoordination of "response to" terms & drugs

[Gwinn Giglio, Michelle]

Hi Chris,

I  thought we decided that "response to drug" would not have any children.
People would annotate to "response to insulin" (for example) which would
have parentage under whatever proper chemical terms it usually does, then if
they new that in this particular case it was acting as a drug they could
co-annotate to "response to drug". I really don't think we should make
children of response to drug.

If using column 16 I would expect the we would annotate "response to
insulin" and then we would need to somehow indicate that insulin in a
particular case was a drug - not sure how to do that.
