Add MAXO Annotation ingest

[kevinschaper]

Create an initial MAXO annotation ingest.

Process is started here: https://github.com/monarch-initiative/maxo-annotation-ingest

This one felt natural to start with doc, then move into tests, then implementation

A draft PR for adding medical action entity & association classes to the biolink model biolink/biolink-model#1523

This may go into the September release using high level classes like Association and NamedThing

@sierra-moxon I'm getting stuck on how to capture a CHEBI extension id of a MAXO term.

If the MAXO term is calcium channel blocking agent therapy (MAXO:0000434) and the CHEBI term is 2,4-diaminopyridine (CHEBI:51599), I'm guessing that's saying that this particular chemical is used for the therapy? So then, this is a qualifier that is making the subject more specific?

maybe subject_derivative_qualifier, because this is a post-composition that means calcium channel blocking agent therapy with 2,4-diaminopyridine?

@iimpulse does that meaning sound right from your end?

Yeah sounds right. Sometimes it can be less specific though. Drug Therapy and then some specific drug. But I dont think that changes anything here. Just something to think about

new release of biolink out with specialization_qualifiers to hold MAXO terms.
