This code repository contains some documentation and scripts to make use of the Sony PRS T1 eBook reader on Linux. The device runs Android in it can be rooted but you can also just modify its local storage as it is visible via USB.
First I wanted to understand how my eReader manages eBooks and annotations. Second I want to read and annotate (!) books in the device and later export the annotations in an open format. Unfortunately the situation for annotations is even worse than the situation for eBooks. De-facto standards for eBooks are EPUB and PDF (plus Amazon's own prison format that I prefer to ignore). For annotations there is no standard format.
Some software such as Okular and Mendeley store annotations in special files. Other software stores annotations in the book files. PRS T1 stores annotations as SVG with metadata in SQLite3, so it can be extracted and transformed to other formats.
Don't expect this project to become a real application. Right now there is only
one command line script prst1.pl
to copy and transform books, notes and
annotations from the device to a local directory (you may first need to create
some directories, database
, notepads
, download
, markup
...)
$ ./prst1.pl -?
A future idea woul include hacking calibre, but I prefer to to stick to one particular software but better work with general data formats.

The database
directory contains several SQLite3 files (.db
) and
a cache.
The cache
directory contains one folder for each book, numbered
(1,2,3...). For each book there is a thumbnail
directory with
images, at least with the cover image main_thumbnail.jpg
. The
markup
directory contains a .png
file and a .svg
file for
each markup in a book (not including highlightings).
The media
directory contains actual ebooks, notes, audio-files,
and images. Media files are referenced by filename in the sqlite3
databases, so don't just rename them!
Have a look at the dbschemas
directory or browse around the database with
SQLite3:
$ ./prst1.pl database
$ sqlite3 database/books.db
