If you are thinking of starting a new open source software project and wanting to look at the what other orgs have done then a new resource has just been released:
The goal of the project is to provide a governance reference resource for all FOSS community members. We’re doing this by collecting and cataloging documents that are in some way related to the governance of FOSS projects.
These documents live in Zotero, not in this repository. Visit the document collection to start browsing and searching the collection.
