Yeah, one reason I stick to Marvin when I need to do annotations is for the various export options.

Mind, those Marvin —> Marvin exports are actually simple zip files. I wish I could import them into Calibre but I just don't have the skill set necessary to create a parser for the Calibre Annotations plugin.

Each annotation is stored in a separate json file named <uuid>.entry.marvinj and a list of all these files is in manifest.json.

Sample manifest.json:

{
  "DeviceVersion" : "10.3.3",
  "Payload" : [
    {
      "filename" : "0051DBCF-6143-4349-9FC7-ED18719666D6.entry.marvinj"
    }
  ],

  "DeviceName" : "iPad",
  "MarvinBuild" : "34",
  "PayloadVersion" : 1,
  "MarvinVersion" : "3.1.2"
}

Sample entry.marvinj:

From my observations:

• selectionSectionName - corresponds to the chapter title
• selectionSectionIndex - index number of file based on epub's content.opf manifest?
• selectionStart & selectionEnd - word count within the chapter/section's html file only?
• ID - I believe Marvin stores all annotations in a single database and this ID corresponds to its index number in Marvin's database
• bookFileHash - MD5 hash of the epub file
