Is there a way to check the number of identifiers over time?

Hello hello!

I was wondering if there is a way to produce a graph of the number of identifiers over time, either globally or (even better) within a specific geographic or taxonomical scope.

So, for instance, can I know how many Lepidoptera identifiers exist for European observations?

This can also work (maybe even better) for the number of identifications rather than identifiers

consider:

• https://api.inaturalist.org/v1/identifications?per_page=0&place_id=97391&taxon_id=47157&d1=2024-01-01&d2=2024-12-31T23:59:59.999
  {"total_results":3877049,"page":1,"per_page":0,"results":[]}
• https://api.inaturalist.org/v1/identifications/identifiers?per_page=0&place_id=97391&taxon_id=47157&d1=2024-01-01&d2=2024-12-31T23:59:59.999
  {"total_results":73964,"page":1,"per_page":0,"results":[]}

you can change the parameters to get get exactly what you’re looking for (ex. use observation_taxon_id instead of taxon_id, use own_observation=false, etc.), and then you can vary the date parameters (which filter based on UTC) to get as many time periods as you need to get your counts or cumulative counts over time. (note that this cannot account for identifications / identifiers that have been removed from the system.)

if you need help automating this, just indicate what sort of tools or scripting languages you’re familiar with, and i can point you to some examples of how to automate.
