There's a new project in the Apache Incubator. It's called Stonehenge, and it's about producing sample applications that implement industry standards. The purpose of these sample applications is to show developers how to develop interoperable applications. There's a new FeatherCast about it, if you want to learn more about what they're trying to accomplish.
By entering the ASF, a project has access to the ASF infrastructure, legal organization, funding, conferences, and a variety of other resources, as well as having access to folks who know how to do Open Source, who have been doing it for more than ten years, and are many of them, fabulous mentors for folks wanting to figure out how this all works.
