Rebuild the ITIS snapshot

Usage

  archive = NULL,
  dir = build_dir(),
  db = td_connect()
)

Arguments

version

snapshot version to write, e.g. "2026"

path to the ITIS SQLite archive; downloaded if missing

Value

Details

ITIS distributes a SQLite database, which duckdb reads directly. n_usage carries the accepted/synonym distinction under two vocabularies, zoological (valid/invalid) and botanical (accepted/not accepted); both map onto accepted and synonym.

ITIS assigns a TSN to synonyms as well as accepted names, so every row here carries its own taxonID – which makes ITIS the reference for the taxadb rules checked by td_validate().

scientificNameAuthorship is taken from ITIS's own author table, keyed on the author id together with the kingdom, since the id is only unique within one.
