As described in the ONNX governance, Working Groups (WGs) are temporary groups formed to address issues that cross SIG boundaries. Working Groups have a have a clear goal measured through specific deliverables and disband after the goal is achieved. Working groups do not own artifacts long term; they create specifications, recommendations, and/or code implementations for submission to the relevant SIGs for approval and acceptance.
New Working Groups are created when there is sufficient interest in a topic area and someone volunteers to be the chair for the group and submits a proposal to the steering committee. The chair facilitates the discussion and helps synthesize proposals and decisions.
Working Groups have their discussions on Slack in dedicated channels. (Older working groups used Gitter rooms which are now archived)
You can find the schedule of meetings on the LF AI wiki
Working Groups store these artifacts, including meeting notes, in this repository. The working group leads have merge permissions on the repo but should only handle PRs related to their working group.

| Working Group | Objectives | Status |
|---|---|---|
| Testing/Compliance | Create tools, tests and APIs to ensure models and backends comply with the ONNX specification | became part of the ArchInfra SIG for now |
| Edge/Mobile | Enable deployment of ONNX models to edge platforms by identifying the ONNX operators that must be supported by mobile and IoT runtimes, defining tool chain requirements, and contributing to ONNX compatibility tests | Stopped as of January 2020 |
