taxonRank categories are not standardised

[stijnvanhoey]

I did a count of the different taxonrank fields, checking the current names in the taxonrank column

taxonRank	kingdom	count
Cultivar	Plantae	7
Form	Plantae	3
Generic hybrid	Plantae	3
Genus	Plantae	26410
Nothosubspecies	Plantae	6
Species	Plantae	3545162
Species aggregate	Plantae	2489
Species group	Plantae	22731
Species hybrid	Plantae	15259
Subspecies	Plantae	155616
Variety	Plantae	12024

Is there a more rigid name convention or vocabulary that we could adopt?

[peterdesmet]

Yes, we should use this vocabulary: http://rs.gbif.org/vocabulary/gbif/rank_2015-04-24.xml It uses lowercase names + no spaces. Here's a mapping of what it should be:

• Cultivar → cultivar
• Form → form
• Generic hybrid → not part of vocab, would like to see examples
• Genus → genus
• Nothosubspecies → would like to see examples
• Species → species
• Species aggregate → would have to see examples
• Species group → would have to see examples
• Species hybrid → would have to see examples
• Subspecies → subspecies
• Variety → variety

@stijnvanhoey can you provide some examples for the ones above?
