Publishing a Story to a custom Publish Channel using Content Station Aurora

Configuring Content Station Aurora for publishing to a custom Publish Channel

Apart from the default Publish channels provided by WoodWing for publishing a Story to in Content Station such as Adobe AEM and Apple News, it is also possible to publish to any custom channel.

The process basically involves publishing the Story in a particular file format to a location where it is picked up and processed in some way. Many different ways of using this exist, but one way would be to publish the Story to a Web CMS environment.

This article describes how to set up a custom channel using an example written in PHP and how to publish it.

Before you start

Before you start, it is recommended to first test the general process of publishing to digital channels in Enterprise Server. Do this by publishing a Story using the option 'Send via e-mail'. Should this not work, troubleshoot this first.

How it works

Every custom channel is configured with an 'endpoint' that Content Station sends messages to when the Story is published.

These messages are sent through the Amazon Simple Notification System, which means the endpoint needs to be able to accept messages in this format.

Every endpoint will receive 2 types of messages:

  • SubscriptionConfirmation. This message is sent when creating the Custom channel is created in Enterprise Server. It confirms that the endpoint is valid and can be used. This allows the endpoint to receive further messages.
  • Notification. This message is sent each time a Story is published to the Custom channel. It contains the id, name and an URL of the article, which in this example is downloaded and placed into a folder. In theory an endpoint can do anything it wants to with an article.

Properties

Users can add properties to a Story which can be used by the custom channel to correctly process and categorize the Story.

How to use it

The following process is used to receive messages on this example:

custom-channel-2.0.0.zip (688KB, November 2017)

Info: Using this sample project requires PHP version 5.5.0 or higher (needed by the AWS PHP SDK).

Step 1. Place the example project on a Web server or any other place where it can be hosted and accessed publicly.

Note: Set the public folder as your document root. When simply copying and pasting the project to your document root, all endpoints have to be prepended with '/public'.

IMPORTANT: A directory named '/public/stories' is needed where articles can be downloaded to and read from by this example; the code will not work when this directory cannot be read or written to.

Step 2. Run './composer.phar install' and resolve any missing dependencies.

Step 3. Set up the Custom channel by following the steps below.

Step 3a. In Enterprise Server, access the Management Console for Content Station.

Step 3b. In the menu, choose Publish Channels.

The Publish Channels page appears showing all Brands. When selecting a Brand, all Publication Channels for that Brand appear.

Step 3c. From the Channel list at the top of the page, make sure that Custom channel is selected.

Step 3d. Click Add Channel.

Step 3e. Fill out the details.

Note: Your changes are automatically saved.

  • Name: The name you want to give this channel. This name will appear in the list of Publish channels that the user can choose from.
  • Target name: The name of the type of target you want to publish to. The user interface will group channels with the same Target name in the Publish dialog.
  • Endpoint URL: The URL that SNS messages will be posted to. This needs to link to the /story/add endpoint located on the public host mentioned in step 1.
  • Reference images by ID only (actual images will not be sent). Select this option when only a reference to any images in the story need to be included, not the actual images.
  • Export formats. Choose the format into which you want to export the story: JSON, HTML or PSV.

Note: The PSV format is the recommended format. This file, based on Prism and with the extension .psv, contains the structure, properties, content, design and related files of the Story. For more information, see the documentation on idealliance.org. For information about the mapping between the Digital article components and the prism fields, see Mapping between Digital article components in Content Station Aurora and PSV classes.

Step 3f. Click outside any of the fields to have the channel automatically created.

Step 4. Create a Story in the Digital editor and publish it to the custom channel. (See Creating a Story for publishing to a custom channel using Content Station Aurora.)
