'is about' cannot be used for 'response to' classes

[tgbugs]

EFO has added a couple of 'is about' axioms to GO response to terms, for example 'response to cisplatin' . 'is about' cannot be used in these settings due the the reasoning chain shown below (is about is for information content entities). The appropriate predicate is probably 'has participant' if you want to make the link explicit, however that may not be correct because the response may come later in time than the presence of the participant, in which case another way to model the process would be required.

There are a couple of other issues that are similar to this that can be revealed by running elk on a combined import of efo and obi.

We've been using 'is about' for a different purpose in EFO for some legacy reasons relating to how EFO is used in the GWAS catalog. This is a known issue and we're working on some new design patterns for this.

There's a related ticket in #8 and some work in progress on the design patterns here https://github.com/simonjupp/efo3-creator/blob/master/designpatterns/responseToDrug_hasInput_chemicalEntity.yaml

@zoependlington @kallia-p @matentzn - we should probably be stripping these is_about links out as part of work on this branch. ('has input' is the correct relation - based on GO schema).

@dosumis Thanks for pointing this out. I have linked this to the main response to terms ticket. #32
