Agreed. If the Linux Foundation doesn't mind relinquishing the OCF name,
ClusterLabs could become the organization that publishes the OCF
standards. Otherwise, we could publish a ClusterLabs API spec and call
it "OCF-compatible", so we could keep the ocf: syntax that everyone's
familiar with.

Last year's HA summit in Brno discussed the reverse possibility, of
resurrecting OCF within the Linux Foundation, and integrating
ClusterLabs with that somehow. The benefit would be to encourage wider
participation, by being part of a larger group with higher visibility
and nonprofit status. But there's probably more bureaucracy with that
