Well, the metadata.db file is a database file (MySQL Lite?). I am not sure if the access interface to this database file is open or not, but it certainly contains the scribbling data of each PDF file. And if I am correct, the PDF scribble and the note share the same base code, so it is possible to get the scribble data out from the metadata.db file, and merge them into the PDF file, actually that's how the DR800 and DR1000 are currently doing.
