The ITIS download applications allows you to download taxonomic groups in two formats. The Taxonomic Workbench (TWB) format is a complete
representation of the ITIS name and its associated elements. The Darwin Core Archive (DwC-A) format is a representation of ITIS data in a
biodiversity informatics standard useful for taxonomic data exchange. Alternatively, ITIS users can download the entire database in several
database formats.
Download TWB - You can create a download file for a specific taxonomic group. The data model is the one used by the
Taxonomic Workbench to read and edit data. It will contain all relevant tables and data in ITIS. The download application
allows searching and narrowing of scope while selecting taxa, and allows the specification of upper and lower rank parameters. The Download
TWB button on the report pages will default to include all names below the selected taxon as well as the direct hierarchy above it up to
kingdom. The original desktop Taxonomic Workbench had a maximum number of name records that could be edited at one time: 32,727.
The maximum number of records that can be downloaded in TWB format is similarly sized.
The TWB file format provides a description of the native Taxonomic Workbench file format.
Download DwC-A - You can create a DwC-A file for download from any name page in ITIS. The ITIS implementation of DwC-A does not include all
ITIS data, and only has specific DwC-A fields. The Download DwC-A button on the report pages will default to include all names below the
selected taxon as well as the direct hierarchy above it up to kingdom.
The DwC-A file format provides a description of how DwC-A files are derived from ITIS data.
Download complete dataset - The full ITIS database may be downloaded in several database
formats. See the instructions for more information.
