Almost a decade ago, I toyed with the idea of something like a web site where a group could build a really detailed index. I called it
ISIS. It never really got off the ground. The progress page is now sort of unintentionally hilarious, at least to me. I'm actually sort of stunned the web pages are still in my directory structure. I guess my wife is right that I never throw anything away.
Every once in a while, I'd get the impulse to try to get ISIS started again, but much of the drive to do so went away when PDF versions of books came on the scene. It was just easier to use Acrobat's batch searching to find stuff. Another reason was that I realized that, if you built the web code for one game, it would be just as easy to build it for all games.
As such, I've been tinkering with Cake PHP to build a more generic on-line indexing groupware type thing. This is more of a programming exercise at this point, to teach myself Cake. If it ever turns into anything real, I'll publish the URL here and people with interest could create a Shadowrun index.
