[COL-Users] NamesIndex missing translations?

[Markus Döring]

Thanks Raffael,

There is a parameter "min" that defines how many sources must have the same name before the name gets included in the results.
By default this is just one, so either iNat or COL. If you only want those where both identifiers exist you would POST to this:

POST https://api.checklistbank.org/nidx/export?datasetKey=3LR&datasetKey=139831&min=2

On first glance I can lots of species names with 2 versions. One with authorship (COL) and one without (iNat).
These are different entries in the names index, as the "canonical" one without authorship acts as a superset of all such names with any authorship.

For example these first rows in the result:

species	Aa achalensis	Schltr.	8H9J	
species	Aa achalensis			https://www.inaturalist.org/taxa/602054
species	Aa argyrolepis	Rchb.f.	8H9K	
species	Aa argyrolepis			https://www.inaturalist.org/taxa/829647

So this is expected behavior. 
To align also these names one would have to use the regular name matching instead.

To match all of iNats names to COL one would do this instead:

POST https://api.checklistbank.org/dataset/3LR/match/nameusage/job?sourceDatasetKey=139831

In a similar manner one can also upload CSV files with names to be matched against any of the datasets in ChecklistBank.


Best,
Markus

In the case of CoL and iNaturalist, I found that only roughly half of the entries (from a recent export) have both the CoL ID and iNaturalist ID set. For the entries pertaining to the rank "species" the situation is particularly bad, only roughly 10% (4353 of 41109) of the entries do any real translation.
