Learn how GA4GH helps expand responsible genomic data use to benefit human health.
Technical Alignment Subcommittee (TASC)
The Technical Alignment Subcommittee (TASC) supports harmonisation, interoperability, and technical alignment across GA4GH products.
To support interoperability of GA4GH products, the Technical Alignment Subcommittee (TASC) provides mechanisms and recommendations to promote technical alignment across GA4GH products. TASC is formed of both GA4GH Work Stream representatives and GA4GH staff who collaborate to create appropriate solutions that may result in documented recommendations and supporting technical implementations.
While TASC functions as a central technical decision-making body, all of its decisions are informed by relevant stakeholders. The work of TASC, including all documentation and decisions, is regularly and openly communicated back to the GA4GH community for feedback both during and after the development of recommendations. TASC also helps to coordinate the activities of the Data Model and Schema Consensus (DaMaSC) group, which aims to create recommendations around data modelling languages, vocabularies and schema sharing.
Approved recommendations
Pagination guide
Pagination provides a structured approach to navigating data, making it easier to process, display, and analyse information. GA4GH supports two types of pagination: token and page based pagination.
TASC-managed registries
Service Info endpoints can be created to allow servers that are using GA4GH APIs to be used within networks. This document details how to add values to the list of Service Info type values.

Process
A project submitted to TASC will go through several steps.
- New issues: issues will enter TASC’s queue for review.
- Assessment: After submission, the TASC leadership team will review the issue to ensure that it contains the required elements, as stated below. If additional information is needed, the submitter will be notified.
- Under discussion: Once a project has been accepted by TASC leadership, it is passed to the team for discussion. In this stage, the team determines a way forward for the project.
- Solution building: The team works towards a solution to the problem.
- Open for comment: The solution is shared broadly with the GA4GH community for feedback.
- Publish: Upon reviewing and incorporating community feedback, the solution is finalised and disseminated to the GA4GH Work Streams.
