Looking for information about programming QR codes

I am looking for 2 pieces of information about building QR codes, but Google is failing me:

1. (Most important) Information about the different message formats; li开发者_JAVA百科ke MEBKM, SMSTO, TEL, GEO, WIFI, etc. i.e. Others not listed and how they are formatted (e.g. "MEBKM:TITLE:{$title};URL:{$url};;").
2. How to build them. Wikipedia has a little info, but not enough. (Currently I am using Google, but I want a little more power)

Thanks!

I don't know how useful this will be (or if you've already seen this and the resources it links to) but the zxing project has a page about contents of 2D barcodes
