XML/EDI - Michael C. Rawlins 2

Accompanying Text:

I was born in the great state of Oklahoma, a state known across the country for oil and cattle. Now, I didn’t grow up on a ranch, but I spent a fair amount of time tromping through pastures when I went fishing with my dad. What does that have to do with anything? I’ve read a lot in the last year about how XML is going to fix all of our problems with EDI. To me, most of it bears a very strong resemblance to what I used to step in out in those pastures.What I would like to do for you all this morning is get out the brush and saddle soap, and clean off some of the … hype about XML; to tell you a bit about what it is, what it will and won’t do for EDI, and what it may mean to you as people concerned with electronic standards for higher education.
