…most of the ProX stuff is available at Github. Not the eXist web pages, yet, but that’s because I’m still experimenting with them and there’s some work left. There’s the Balisage demo, and there’s the basic ProXist stuff, with pipelines and XQueries and such, and there’s the authoring environment (with Relax NG schema, FO, etc), but no instructions on how to get any of it to run, yet.
I have a test app running locally, a little something that is about as simple as I can make it, but since I am not a web developer (I’m a markup geek), the HTML is awkward, the CSS nonexistent apart from the default eXist stuff, and the XQueries somewhat painful. I do think it’s going to be pretty cool, though, and look forward to presenting it at XML Prague.
