Update to Book Package Specification.
April 14, 2016
The iBooks Store Book Package Specification has been updated to include the following:
- Series Identifier. iBooks assigns every series a unique Apple ID. If you do not know the series’ Apple ID, you can do a metadata lookup after delivering the metadata. Look for the
<apple_id>tag within the
<series>block. To avoid ambiguity in subsequent updates, use the
<apple_id>tag instead of, or in addition to, the series title.
- Contributor Localizations. You can now provide localized names of a book’s contributors in each language or territory where the book is sold.
- Content Update Behavior. A new appendix describes the process behind updating content and includes definitions, descriptions of content review statuses, and a table listing the tags that may require a ticket in certain circumstances.
