What mechanism can approve content added by a digital marketer to a website?

The workflow engine is a crucial component for managing content approval processes within many digital marketing and content management systems. Its primary function is to streamline and automate the workflow associated with content creation, review, and approval.

When digital marketers add content to a website, the workflow engine ensures that this content goes through a predefined series of steps before it becomes public. This might include drafts being reviewed by editors or approvers, receiving feedback, and making necessary revisions. The workflow engine helps in enforcing standards and ensuring that only vetted and approved content is published, which enhances content quality and maintains brand integrity.

In contrast, while an author server and a publish server play important roles in content management—where the author server is used for creating content and the publish server is meant for displaying that content to the public—the workflow engine specifically focuses on the approval mechanism that governs how and when content transitions from one phase of creation to publication. Apache Sling, as a framework for building web applications on content repositories, also does not directly relate to the approval process like the workflow engine does. Therefore, the workflow engine is the most accurate choice for approving content added by a digital marketer.
