Blog Feature


The blog feature for AEM Communities has transformed from an authoring activity to a true community activity that takes place in the publish environment.

The blog feature supports providing community information in a journaling format. Blog entries are made in the publish environment by authorized members (registered, signed-in users).

The blog feature provides:

  • Publish-side creation of blog articles and comments
  • Rich text editing
  • Inline images (with support for drag and drop)
  • Embedded social networking content (oEmbed support)
  • Draft mode
  • Scheduled publishing
  • Compose on-behalf (a privileged member can create content on behalf of a different communty member)
  • In-context and bulk moderation of blog articles and comments

This section of the documentation describes

  • Adding the blog feature to an AEM site
  • Configuration settings for blog components

The components Journaland Journal Sidebar are titled Blog and Blog Sidebar.

The blog feature found in AEM 6.0 and earlier releases is now removed. It was based on a template and only allowed authors to create content in the author environment.

Adding Blog Components to a Page

If it is desired to add a blog to a page in author mode, use the component browser to locate

  • Communities / Blog
  • Communities / Blog Sidebar

And drag them into place on a page where the blog should appear.

For necessary information, visit Communities Components Basics.
