Final Fantasy XIV Item Database
I've started screwing around with creating an item database primarily intended for crafting within Final Fantasy XIV.
Right now it doesn't do all that much, but it includes all the recipe information available from the Lodestone website. I'll be adding more information to it as I go along, although at some point it would be nice to allow external submission of data. For now the data is currently stored in a flat file, although that's changing in a future version.
Anyway, feel free to screw around with it. It should work on most recent browsers, I haven't tried it with Internet Explorer.
