A couple of field name inconsistencies.

[guignonv]

Plural forms should be used instead of singular (to be consistent):

• BrAPI-Genotyping > Variant Sets > /variantsets/{variantSetDbId}/variants (array) variantSetDbId --> variantSetDbIds

• BrAPI-Germplasm > Germplasm > /search/germplasm (array) genus -> genera

• BrAPI-Germplasm > Germplasm Attributes > /search/attributes (array) studyDbId -> studyDbIds

• BrAPI-Phenotyping > Observation Variables > /search/variables (array) studyDbId -> studyDbIds

I also found some inconsistencies and will add them here instead of opening a new issue:

• there exist two spellings for timestamp fields: <...>TimeStamp and <...>Timestamp (cf. observation.observationTimeStamp and germplasmAttribute.submissionTimestamp). Whichever is the preferred one, the other should be updated
• scale.units should be scale.unit as its type is str and not list of str
• is ontology.licence spelled correctly? (BE: licence vs. AE: license) Or should both spellings be allowed?

And also in BrAPI Core > Studies > /studies (array) seasons -> seasonDbIds

lol ok I spent more time researching this than I would like to admit: licence and license are both acceptable. As you pointed out license is the USA version (because we have to be different). For the rest of the English speaking world, licence is a noun (as in "this ontology has a licence") and license is a verb (as in "this ontology is licensed by @feserm)

For our purposes, I think licence is fine because we are using it as a noun, and we Americans can sound it out if we have to 😄
