I'm currently preparing a large collection of scanned documents for Wikisource.
Do we have any guidance on internal metadata inside djvu files? It
appears that I can just cram in arbitrary XML into the DJVU files, but
I can't find any good schema for this on the Internet. If no one has
suggestions, I'll just make it up as I go.
Of course, the same metadata will also be provided on the media pages,
but I believe that the internal metadata will be useful to others who
obtain our files.
