Passing Binary Data between Experience Manager Workflow Steps

You can develop a custom Adobe Experience Manager (AEM) workflow step that sets a binary value that can be retrieved by another step in the same workflow. For example, assume you read a byte array and you need that value in a later step. You can store the value and retrieve it in a later step.

To read and write binary values in an AEM workflow, you need to write custom steps. A custom workflow step is implemented as an OSGi bundle that you can build using Maven and the AEM Workflow APIs that belong to the com.adobe.granite.workflow.exec package. For information, see Package com.adobe.granite.workflow.exec.

To demonstrate how to pass values in workflow between steps, this article uses the following workflow model.
