GA4GH Beacon

Maintained by GA4GH Discovery Work Stream

What it helps you do

Beacon supports federated queries across genomic variants and related individuals, biosamples, cohorts, runs, analyses, filters, result granularity, and handover links.

01

Where it fits and where it does not

Use these four checks before committing implementation time.

Use it when
Privacy-aware discovery of relevant genomic and biomedical datasets before a researcher begins a separate authorization and access process.
Limits
Beacon is a discovery protocol, not a complete authorization, consent, or privacy guarantee. Record-level and count responses can disclose sensitive information, and local schemas, filters, and handovers can still diverge.
Best for
Omics and Clinical and Rare disease teams working across Exchange → Learn + reuse.
Maturity
ScalingUsable now, but adoption or tooling is still developing. Pilot the exact stack first.

See it in the workflow

This view shows the input, the change the standard introduces, and the resulting output.

  1. InputWhat starts

    Omics and Clinical and Rare disease source data, metadata, and local mappings

  2. BeaconWhat changes

    Use Beacon as a pinned standard across Exchange → Learn + reuse

  3. OutputWhat becomes possible

    A handoff the next system or team can validate against the same release

Readiness gateBeacon is a discovery protocol, not a complete authorization, consent, or privacy guarantee. Record-level and count responses can disclose sensitive information, and local schemas, filters, and handovers can still diverge.

03

A concrete example

Publish service and configuration metadata, pin the v2.2.0 schemas used by each entry type, constrain response granularity by authorization context, validate filters, and perform privacy testing before federation.

Why it matters: Supports machine-driven cohort and dataset discovery, while returned matches do not by themselves establish access rights, harmonized records, cohort comparability, or fitness for training.

04

What it fits with

Can expose VRS-aligned variants, Phenopackets-compatible clinical context, DUO use conditions, Expmeta experiment properties, and handovers to DRS or other controlled-access services.

05

Implementation starter

Start with one bounded handoff. Pin, test, and review it before scaling.

  1. Define one handoff, its accountable owner, and the decision Beacon must support.

  2. Pin the exact version and companion artifacts: v2.2.0 release · GA4GH-approved v2.0 baseline.

  3. Map one representative input to the required standard artifacts.

  4. Test the result against the canonical source and record every exception.

  5. Preserve the source data, mappings, and review evidence before scaling.

06

Test the main limitation

Risk

Beacon is a discovery protocol, not a complete authorization, consent, or privacy guarantee. Record-level and count responses can disclose sensitive information, and local schemas, filters, and handovers can still diverge.

Test

Run one representative end-to-end pilot and record exactly where Beacon loses context, needs an extension, or depends on another standard.

Risk

Machine-readable output may still be unfit for analysis or ML.

Test

Test the output for missing context, provenance, terminology alignment, time leakage, and the intended downstream decision. Supports machine-driven cohort and dataset discovery, while returned matches do not by themselves establish access rights, harmonized records, cohort comparability, or fitness for training.
