As I have been studying the DFDL and working on the primer, I have been thinking about how it might be used in Grid applications. A virtual walk around NCSA has produced quite a few non-trivial use cases. What I would like to do is put some of these out to the group, for discussion. Since I am relatively new to the DFDL game, I expect that some of my ideas are naive or flat wrong. I have typed up detailed notes on 4 cases. I have a couple of other cases I'm trying to document. I attach these notes here. Sorry, it's a bit long! -- --- Robert E.
