title_body: self-hosted, self-updating book repository My Amazon Kindle synchronizes with my Amazon library.  Additionally, I have a Calibre library, which publishes its contents via a web server.  As far as I know, you can only copy books from the server, whereas Amazon functionally rsyncs your book, keeping your highlights, notes, and current reading position updated.  Is there any technique or product which facilitates similar functionality using a self-hosted solution?
  
  Thank you
upvoted_answer: At this time, I'd say "no".  When you read an epub in Calibre's internal reader it sets a bookmark in a file inside the epub, but most readers set that bookmark in a related (usually sqlite) database. And there's no standard for the bookmark format (well, there is, in epub3, but I haven't found anybody using it yet...).
  
  But if you're willing to settle for using a particular set of devices, you could probably fairly simply extract the bookmarks from those, and translate them to be useful by the other devices. Notes, otoh, are much more complicated. Calibre does have a "universal" notes plugin--unfortunately, it requires support to be written for each device driver, and I think there are only one or two drivers that have it.
