HOWTO: install Fedora-commons repository software on Debian

So I’ve been using Fedora-commons for almost a year, first off, no it is NOT the Linux distribution, it is a digital repository used by libraries, museums, etc, worldwide to keep track of their digital collections.¬†For this Fedora-commons is very good at its job, but there was a steep learning curve when I first jumped in with, a complaint I’ve heard repeated by many who aren’t Java jockeys (just made that up).
