All testing is to be done in Bokbasen’s test environment (*.webbe.no).
If you should decide to test against the production environment, be aware that all purchases are real and will be invoiced by the publisher. All functionality must be tested in test environment before live testing.
| Note |
|---|
Important! Credentials are different in test and production environments for the same bookstore. |
Test is available at all times. We recommend that the bookstores maintain the link between their test environment and ours also after release. DDS is constantly being developed. New and improved services will always be available for testing in test before deployed to production.

It is the publisher who decides which DRM to use on the e-book. It is also an option not to use any DRM (NoDRM). DDS support to three types of DRM:
Adobe Content Server 4 (TDRM) - being phaced out
Watermarking (SDRM)
About formats
Bokbasen supports the following audio book formats:
...
Metadata about e-/audio books are delivered as a separate service. Bokbasen delivers metadata about all types of books. You can read about formats and how to import and implement metadata to your site in the documentation for metadata services (Onix from Bokbasen and Metadata Export Service).
Established customers can contact us to start the delivery of metadata for e-/audio books in the same stream as received today.
...
Update and populate your system with data from the inventory service and the Bokbasen Metadata export API.
| Note |

IMPORTANT! First update your system with the required metadata from the API. This is not a part of the e-/audio book distribution; it's a separate service. |

Import the metadata updates from Bokbasen metadata API (all books available so you need to filter based on the data to load only the desired books, audio, e-book etc.)
Make a query to DDS Inventory REST API
Display metadata for all e-/audio books with published status = true combined with
access = true
The store should be able to display metadata of an e-book not published but with
a published excerpt. Important not to sell the e-book by accident. Note that for audio books the feed will never give an excerpt. Audio book excerpts are only available through Bokbasen metadata download object API.The store should be able to display metadata of an e-/audiobook for presales. Important to log the orders, but you cannot initiate downloads before the e-/audio book is published.
It is important to note that from the metadata service you will get data on all books registered in the database. This includes e-/audio books, which aren’t published yet, are unpublished or the store doesn’t have access too.
It’s necessary to implement a set of rules for which metadata to display on the site based on formats, status, information etc. There are different issues for physical book and e-/audio books.
For e-/audio books the most important rule is to display only the e-/audio books published in DDS. This is to avoid selling e-/audio books that can’t be delivered. Metadata about an e- /audio book can be available months ahead of publishing. The status provided in the metadata services is not enough to decide if the store can sell the e-/audio book:
...
All DDS services have to be authenticated against the Bokbasen authentication service as described below. The Bokbasen authentication service is used across Bokbasen’s services, so you also use the same process for retrieving Metadata. The documentation for the authentication API is also available online at
Bokbasen is renewing its Authentication service. Look her for more information.

DDS Orders
Introduction
DDS make available products that can be sold in an online store. This API describes how to place orders to DDS for the e-/audio books sold. The process for placing an order is to first call the order REST API, then using the GET content API to retrieve the item that was bought.
...
An order is placed at the time of a valid purchase from the end-user. This is for a product to be made available to the customer in all services. The bookstore calls this on behalf of the customer.
If id it is specified for an order id, the order is attached to this and can’t be changed. There are some variations in the data you need to send in depending on what type of DRM the book

Downloading a product
The download service (/content) gives access to the end product based on an order placed in DDS. The process is the same for all kinds of content and delivery methods, but the client will need to handle the actual delivery different based on the format and delivery protocol (e.g. download of an EPUB vs. Streaming an Audio book over HLS). Which delivery methods used is based on the format of the file and the player-/reader application’s requirements.

The Bookshelf (represented by an OPDS-feed) is used to give the consumer access to download his books on any app or device that supports Bokskya. The store has access to fetching a customer’s OPDS-feed and deliver in an app, to a reading tablet or for download from the Bookstore (My Page).
In the OPDS-feed there are links to the REST interface to download all the consumer’s e- /audio books and references to fetch the cover image of the book.

It is strongly recommended to use the OPDS feed to get the URL needed to access the book, as this is will most likely:
