Rob, a couple quick follow-ups... Did not even know about S-100 -- do you have any insight on when this will be published and do you have any clue if NOAA will move to publish new chart data that conforms to S-100 anytime soon? Is S-100 really GML? That seems like a slight step backwards...I've done some work on massive datasets, and XML is nice for exchange and all that, but not for performance.
My plan for this would be to write the low-level parsing code that transforms the data into basic, sorta-primitive java OO versions of the records that S-57 defines. This is the first layer. The second layer would be somewhat pluggable, so you could use the library to convert those records into your own object model, but I intended on supplying an implementation that would push those records into the GeoTools OGC Feature model as the next (optional) layer. Was not really sure how much of a paradigm mis-match I would encounter here until I got there. Thanks for the input. If anything I think an OSS java S-57 library would be useful anyway (none exist today)...and I want to learn the specs better, so I think I'm going to give it a shot.
