Raised by @duncanbeevers in the TDC meeting:

Should OAI apply to FOSS Sustainability Fund?
https://www.opentech.fund/funds/free-and-open-source-software-sustainability-fund/

Eligibility

Release: Software has been released for at least 3 years.
Updates: The project pushes updates at least 4 times a year.
Development: Active coding towards the software has occurred in the last 2 years.
Userbase: The project has a substantial base of active users, if it is an app or other user-facing tool.
Keystone technology: OTF aims to support projects with many dependencies, to maximize long-term impact in the broader FOSS ecosystem.

Note that "software" here actual includes specifications according to their web site. Our most obvious difficulty qualifying would be the release cadence.

Pinging @swaldron58 as GitHub won't let me assign this to you for some reason.
