Somewhere I managed to scare up the hojillion ($107) pieces of cash to buy the stuff. It's not that big either, I am disappointed. :) As for doing this as my thesis, I think that it is in fact what I want to do. I'll need to restructure a few things (change of scope etc.) with my advisors and ensure that I have an 'out' if things get out of hand, but the rewards that I could reap are worth the risk and work. That however, is between me and my advisors. So I guess I begin with reading and grokking all there is to know about ISO 19117, yes? > I think that whatever we do, working through progressively more > complex > examples (start with Points, end with wind barbs) is critical to > understanding both the capabilities and limitations of the > framework, and > determining if it meets the wind barb needs.

Perhaps I shouldn't worry about details like this yet... *snip* Enough questions out of me. :) -Patrick ------------------------------------------------------------------------- Using Tomcat but need to do more?
