Genomes OnLine Database (GOLD) v.6: data updates and feature enhancements.

Area of Science:

• Genomics
• Bioinformatics
• Data Management

Background:

• The Genomes Online Database (GOLD) is a crucial resource for tracking microbial genome sequencing projects worldwide.
• It provides a structured catalog of sequencing and analysis projects with associated metadata.

Purpose of the Study:

• To detail the updates and new features implemented in Version 6 of the GOLD database.
• To highlight improvements in data organization, submission capabilities, and integration with other systems.

Main Methods:

• Manual curation of sequencing project data.
• Implementation of a four-level classification system: Study, Organism/Biosample, Sequencing Project, and Analysis Project.
• Integration of over 312 metadata fields, including controlled vocabularies.

Main Results:

• GOLD v.6 organizes extensive data, including 26,117 Studies, 239,100 Organisms, 15,887 Biosamples, 97,212 Sequencing Projects, and 78,579 Analysis Projects.
• The system supports diverse project types (e.g., metagenomes, single-cell genomes) and complex analyses.
• Enhanced web interface facilitates submission and integration with systems like Integrated Microbial Genomes (IMG).

Conclusions:

• The updated GOLD database (v.6) offers a robust and comprehensive platform for managing and accessing global genomic data.
• It supports the Genomic Standards Consortium (GSC) Minimum Information standards, promoting data consistency and interoperability.
