Working Groups Overview

Working groups deliver concrete outcomes such as SEPs, extensions, and code. Each runs under a charter that sets its scope, leads, and operations. This page lists the active working groups. The Working groups and interest groups page explains how groups work and how to join or form one, and the charter template covers submitting a charter.
