Taxonomy report

General information about a taxonomic identifier

The downloaded taxonomy data package contains a taxonomy data report in JSON Lines format in the file:

ncbi_dataset/data/taxonomy_report.jsonl

Each line of the taxonomy data report file is a hierarchical JSON object that represents a single taxonomy record. The schema of the taxonomy record is defined in the tables below where each row describes a single field in the report or a sub-structure, which is a collection of fields. The outermost structure of the report is TaxonomyNode.

Table fields that include a Table Field Mnemonic can be used with the dataformat command-line tool's --fields option. Refer to the dataformat CLI tool reference to see how you can use this tool to transform taxonomy data reports from JSON Lines to tabular formats.
