Shove it on GitHub, it's edit in-browser functionality means it is accessible to non-techies. Problem solved.

All it needs is someone to pick a master format for the text and run with it. That should be someone with enough domain knowledge to choose wisely. I would say something like markdown with embedded metadata (like how you format a blog post with jekyll), but I admit I don't know anything about the requirements of the project.
