## What it is
The authoritative repository maintaining Pango lineage designations for SARS-CoV-2, hosting the lineage description list, sequence designation list, and alias key. New lineages are proposed via GitHub issues and reviewed by the Pango designation committee.

## Use cases
- look up which mutations define a SARS-CoV-2 variant lineage
- resolve Pango lineage aliases to full names
- suggest a new coronavirus variant lineage for designation
- download the latest lineage designation data for phylogenetic analysis
- check whether a genome sequence has been assigned to a Pango lineage

## When to choose
- you need the canonical, up-to-date Pango lineage designations for SARS-CoV-2
- you are building tools like pangoLEARN or scorpio that consume lineage data
- you want to propose or track new variant lineage designations

## When to avoid
- you need lineage designations for pathogens other than SARS-CoV-2
- you want a software library rather than curated data files
- you need historical variant data frozen at a specific date

## Facets
- artifact type: dataset
- maturity: active
- function: data-generation, documentation
- domain: bioinformatics, healthcare, data-science
- platform: python, cross-platform
- tags: pango-lineages, sars-cov-2, genomics, viral-variants, gisaid, phylogenetics, nomenclature
