Accessing the Metadata Processing Instructions

When you open the DPI interface you will see an accordion with all available format options. You can drag and reorder the accordions at any time.

From the DPI Interface click and expand the Document Metadata accordion bar. The metadata forms will open. You only have to set the options for a book once.

The DPI Metadata section is where you enter and maintain the common metadata required for all formats. 

There are two main sections. Descriptive Metadata and Indentifiers.

Descriptive Metadata

ePub mandatory metadata. EPub requires the Title, Identifier Language and Date metadata fields to be included. It is strongly advised that you add at least these three fields immediately when creating a new book. Other fields can be added at any time.

Identifier Metadata

DPI allows you to specify multiple Identifiers, usually an ISBN reference for different formats.

Depending on your ISBN strategy, you may use the same ISBN for all formats, or various formats may require different ISBNs.

You must enter the identifiers for all formats that require identifiers. Remember that an Identifier is compulsory for a valid ePub2 or ePub3.

The identifier is used as the filename for all e-book formats and PDFs. If you do not enter an identifier the e-book will be generated with the default Identifier NOID.

The available Identifiers are: 

Print ISBN


Kindle ISBN


Large Print ISBN
