I wrote a small 'naviserver.rdf' xml-like file in DOAP vocabulary (http://usefulinc.com/doap)
Stephen suggested DOAP some months ago for modules. It's nice to describe the basics of a projects, (DOAP aka "Description of a Project"). I don't know how widely adopted that DOAP thing is, but it might not harm. If it's ok for you I would commit it to the same location as NEWS and Changelog.
