HL-7 documentation has to be purchased from hl7.org. They control copyright and so legal free copies aren't available AFAIK.

If you feel thrifty and are willing to work out some of the information yourself, the HAPI project might be a good place to start. If you look at the code you can see how some of the different segments are represented.
