Description

The "ISBN" datatype allows the validation, storage and retrieval of a single ISBN (International Standard Book Number) value. From version 3.9 of eZ Publish, this datatype also supports the new ISBN-13 format. Note that from the 1st of January, 2007, the book industry will start using 13 digit ISBN codes (ISBN-13) to identify all books in their supply chains. The following screenshot shows the class attribute edit interface for this datatype.

The "ISBN-13 format" checkbox makes it possible to configure the datatype so that it validates and stores the ISBN codes according to the ISBN-13 format (this is off by default). Note that the object edit interface will appear differently (one input field instead of four) when this checkbox is checked (see below).
