#KOReader calibre plugin
A calibre plugin to synchronize metadata from KOReader to calibre.
KOReader creates sidecar files that hold read progress and annotations. This plugin reads the data from those sidecar files and updates calibre’s metadata based on them. It is inspired by the Kobo Utilities plugin, that synchronizes reading progress between the original Kobo firmware (“Nickel”) and custom columns in calibre.
Note that at the moment the sync is one-way—from the KOReader device to calibre—and only works for USB devices. Support for smart devices is on the to-do list.
Releases will also be uploaded to this plugin’s thread on the MobileRead Forums. If you are on there as well, please let me know what you think of the plugin in that thread.
#Using this plugin
#Download and install
- Download the latest release from here.
- Go to your calibre’s “Preferences” > “Plugins” > “Load plugin from file” and point it to the downloaded ZIP file
- Restart calibre
- Pick and choose the metadata you would like to sync and create the appropriate columns in calibre. These are your options:
- A “Floating point numbers” column to store the current percent read, with “Format for numbers” set to
- A regular “Text” column to store the location you last stopped reading at.
- A “Rating” column to store your rating of the book, as entered on the book’s status page.
- A “Long text” column to store your review of the book, as entered on the book’s status page.
- A regular “Text” column to store the reading status of the book, as entered on the book status page (“Finished”, “Reading”, “On hold”).
- A “Date” column to store the date on which the book’s status was last modified. (This is probably the date on which you marked it as read.)
- A regular “Text” column to store the MD5 hash KOReader uses to sync progress to a KOReader Sync Server. (“Progress sync” in the KOReader app.) This might allow for syncing progress to calibre without having to connect your KOReader device, in the future.
- A “Long text” column to store the raw contents of the metadata sidecar, with “Interpret this column as” set to “Plain text”.
- Add “KOReader Sync” to “main toolbar when a device is connected”, if it isn’t there already.
- Right-click the “KOReader Sync” icon and “Configure”.
- Map the metadata you want to sync to the newly created calibre columns.
- Click “OK” to save your mapping.
- From now on just click the “KOReader Sync” icon to sync all mapped metadata for all books on the connected device to calibre.

#Notes & Tips
- My first attempt was actually to sync calibre with KOReader’s read progress through the progress sync plugin and a sync server. Read here why that did not work. This plugin might actually make that possible now by allowing you to store KOReader’s MD5 hash in calibre.
- Right now this plugin only supports KOReader devices connected by USB. Adding support for wirelessly connected devices (using the calibre plugin) is next on the list. (See calibre’s repository for their end of the latter.)
- calibre allows you to auto-connect to a folder device on boot, which greatly speeds up your workflow when testing. You can find this under “Preferences” > “Tweaks”, search for
auto_connect_to_folder. Point that to the
dummy_device folder in this repository. (I have included royalty free EPUBs for your and my convenience.)
- I work in PyCharm, which offers a remote debugging server. Follow these steps to set that up. To enable that in this plugin, add
CALIBRE_PYDEVD=1 to your
