Policies & Governance

Governance Summary

The OCFL specification is governed by its Editorial Board. The group meets every other week to discuss issues related to the specification and how we can collaborate with the community. We host community meetings to hear about how the community uses the specification; information provided by the community impacts the Editors' decisions about the specification.

There is no formal governance for the community.

Primary Funding Source


Funding Needs

Right now the editorial board is leaning into their institutions' professional development and travel funding to ensure they can meet and focus on doing the work to advance the specification - oftentimes doing this by coordinating meetings around shared conferences. Any funding that would be provided to the community would help to fund the editorial group's travel - either to conferences to promote OCFL or to meetings so improvements can be made to the specification.
