Okay, that was a pretty confusing title, but thanks for clicking anyways ;-)
Bravo, Greg! Just found his recent entry (http://blogs.sun.com/roller/page/greimer/20041008#tree_of_data_sea_of), where he discusses Webs of Data and Topic Maps. It's an interesting read, and now maybe Greg will be able to start experimenting with XTMs.
BTW, Greg and Lars, I'm still working on my Star Wars Topic Map. Perhaps it will be easier, now that I've found TSaxon to process the pages I need. Stay tuned...
