For submitting IDs that are not in the IDs suggested by the AI, it is convenient to manage a “Bookmarks” taxonomy (there is one for every taxonomic filter defined in the tool settings). I use these bookmarks for instance to identify Cassia leptophylla, a taxon that never appears in the AI suggestions:
The combobox above shows all my bookmarks attached to the filter “Subfamily Caesalpinioideae”.
Using the checkbox to show all “Ancestors”, the button to show all “Children” of the taxon selected (can be applied recursively), it is possible to browse the whole taxonomy. Using the button “Add” to bookmarks, it is then possible to add any taxon to the bookmarks.
In addition to the AI suggestions and to the Bookmarks, it is also convenient to browse an “Overview” taxonomy attached to the filter selected and containing the filter taxon itself, all its brother taxa and all its children taxa:
The colored raw corresponds to the best match between the contents of this taxonomy and the best ID for the observation being reviewed.
The 3rd taxonomy available is the one generated from the AI suggestion for the observation being reviewed:
So, the user has 3 taxonomies available (1 entirely managed by the user) for selecting an ID to submit, plus the tools for browsing the whole taxonomy available in iNaturalist when this is not enough. The display of these taxonomies is automated, the user never has to order the taxa manually.
