Is there a tool / code snippet that allows downloading of taxonomy data from the site?

[pisum]

besides the API, there are 2 ways to get a full taxonomy download nowadays, though these are both monthly snapshots, as opposed to live data.

Option 1 (includes common names):

@pisum

you can get the monthly-generated iNaturalist Taxonomy DarwinCore Archive, which includes separate files for each set of common names: https://www.inaturalist.org/taxa/inaturalist-taxonomy.dwca.zip.

Option 2 (no common names):

@pisum

As you may have heard, iNaturalist officially launched its “iNaturalist Licensed Observation Images” open dataset on AWS on 15 April 2021. Most of the dataset consists of CC-licensed and non-copyrighted images from observations in iNaturalist, but there are also 4 metadata files that go along with these image files which provide additional information about the photos, associated observations, associated observers, and iNaturalist’s taxonomy.
