I would like to encourage GenJ to add Elizabeth Shown Mills' Evidence Style source capability to GenJ. To that end, I have parametrized it and described it at http://jytangledweb.org/genealogy/evidencestyle . I am encouraging other genealogy software companies to look at this site as well, and they are free to take and use anything at the site. The major genealogy software companies already have adapted Evidence Style capability. My web site can be an aid to those that haven't, and maybe even leapfrog the others if all of my recommendations at the site are adopted. I'm not a Java programmer, so sorry, I can't help beyond the parametrization, but that is most of the battle, conceptual and coding.
I hope that your developers see merit in this and adopt it. Professional genealogists pretty much all have adopted the Evidence Style source reference style. If you doubt that, just Google around.
Anyway, this is a no strings attached gift. Feel free to use, abuse, modify, extend, etc.
Enjoy!
John
P.S. I'm not here much. If anyone needs to contact me, the best way would be to use my email link on the above web site.
