NCBI Taxonomy: a comprehensive update on curation, resources and tools.

Area of Science:

• Biotechnology
• Bioinformatics
• Genomics

Background:

• The NCBI Taxonomy is a comprehensive resource for organism names and classifications.
• It supports the International Nucleotide Sequence Database Collaboration (INSDC) nucleotide and protein sequence databases.
• Previous versions were reviewed in 2012.

Purpose of the Study:

• To detail the significant improvements and architectural changes in the NCBI Taxonomy resource since 2012.
• To highlight the benefits of the new NameBank framework for data management and annotation.
• To document updates to tools, resources, and curation practices.

Main Methods:

• Transition from a single SQL database to a series of linked databases using the NameBank data framework.
• Implementation of enhanced annotation for synonyms, nomenclatural properties, publication tracking, scientific authorities, and types.
• Documentation of curator practices for major taxonomic groups.

Main Results:

• The NameBank framework allows for more detailed adjustment of relations among data elements.
• Expanded annotation capabilities include flagging names with specific nomenclatural properties.
• Improved tracking of publications associated with taxonomic names and enhanced annotation of scientific authorities and types.

Conclusions:

• The updated NCBI Taxonomy provides a more robust and detailed system for managing and accessing biological sequence classifications.
• These enhancements improve data accuracy, discoverability, and utility for researchers.
• The resource continues to be a vital component of bioinformatics infrastructure.
