A Working Group is established by first defining a charter that can be ratified by the TC. A charter is a statement of purpose, a list of responsibilities and a list of initial membership.
A working group needs 3 initial members. These should be individuals already undertaking the work described in the charter.
The list of responsibilities should be specific. Once established, these responsibilities are no longer governed by the TC and therefore should not be broad or subjective. The only recourse the TC has over the working group is to revoke the entire charter and take on the work previously done by the working group themselves.
If the responsibilities described in the charter are currently undertaken by another WG then the charter will additionally have to be ratified by that WG.
You can submit the WG charter for ratification by sending a Pull Request that adds the charter to the WORKING_GROUPS.md document, which adds it to the list of current Working Groups. The WG is considered to be chartered once that PR lands. Once ratified the list of members should be maintained in the Working Group's README.
Once the TC ratifies a charter, the WG inherits the policies established by the TC for governance, contribution, conduct and an MIT LICENSE. WGs are free to change these documents through their own governance process but should retain at least the spirit of the original versions. The template documents provided in this directory are provided to help bootstrap that process:
