Per the Appia Project Charter, Steering and General Members must also hold at least a Silver membership with the Linux Foundation, scaled by consolidated employee count. Whether Contributor Members are also required to hold LF membership is not settled in the documents on file — the Charter’s own wording excludes Contributor from this requirement, though this should be confirmed directly with the formation team before it’s published, as smaller/non-profit applicants may instead qualify for the Linux Foundation’s separate, lower-cost Associate membership class.
