Missing enum for approval status
Describe the bug
Missing enum for highest FDA approval status and drug regulatory status world wide
Expected behavior
Restore FDAApprovalStatusEnum from a previous Biolink version or or define a new enumeration.
What working group (or team) did this request originate from? MolePro
see also #869
@vdancik - highest FDA approval status and drug regulatory status world wide are still their own slot in Biolink (have not changed). Do you want them to be part of a enum? I think the original intent was to save FDAApprovalStatusEnum for those statuses that were not the highest -- these two slots were to help "denormalize" the edge metadata to a chemical node for easier retrieval.
Clarified at the DM call 03/28/24 - we would like an enumeration to constraint highest FDA approval status with a set of permissible values. drug regulatory status worldwide should have a similar permissible value enumeration.
The enum change was to accommodate "edge level" annotation; we might need a different PV set for this.
see: MaxResearchPhaseEnum (would have to add approval details to max research phase).
For discussion in chemical WG (@vdancik) - DM discussion was to have two properties on nodes similar to edges.
