With Adobe Experience Manager (AEM) as a Cloud Service, Content Fragments lets you design, create, curate, and publish page-independent content. They allow you to prepare content ready for use in multiple locations/over multiple channels, ideal for headless delivery. They can also be used together with Multi-Site Management to enable you to reuse your content.
Content fragments contain structured content:
Content fragments can also be delivered in JSON format, using the Sling Model (JSON) export capabilities of AEM core components. This form of delivery:
Content Fragments are a Sites feature, but are stored as Assets.
They are now primarily managed with the Content Fragments console, though they can still be managed from the Assets console. This section covers management from the Assets console.
There are two editors for authoring Content Fragments. This section covers the original editor, primarily accessed from the Assets console. See the Sites documentation, Content Fragments - Authoring, for details of the new editor (primarily accessed from the Content Fragments console). Both editors have a toggle switch in the top toolbar to provide quick access to the other editor.
This and the following pages cover the tasks for creating, configuring, maintaining, and using your content fragments:
The number of communication channels is increasing annually. Typically channels refer to the delivery mechanism, either as the:
However, you (probably) do not want to use the same content for all channels - you must optimize your content according to the specific channel.
Content fragments allow you to:
These content fragments can then be assembled to provide experiences over various channels.
Content Fragments and Experience Fragments are different features within AEM:
Experience Fragments can contain content in the form of Content Fragments, but not the other way around.
For more information, see also Understanding Content Fragments and Experience Fragments in AEM.
AEM Content Services are designed to generalize the description and delivery of content in/from AEM beyond a focus on web pages.
They provide the delivery of content to channels that are not traditional AEM web pages, using standardized methods that can be consumed by any client. These channels can include:
Delivery is made in JSON format using the JSON Exporter.
AEM Content Fragments can be used to describe and manage structured content. Structured content is defined in models that can contain various content types including text, numerical data, boolean, date and time, and more.
Together with the JSON export capabilities of AEM core components, this structured content can then be used to deliver AEM content to channels other than AEM pages.
See Headless and AEM for an introduction to Headless Development for AEM Sites as a Cloud Service.
AEM also supports the translation of fragment content. See Translating Assets for further information.
When accessed through the Assets console, you can use MSM and create Live Copies for your fragments.
For more details, see Reuse Content Fragments using MSM for Assets. This enables inheritance for both variations and individual fields of your fragments.
If you want to use MSM (which creates copies of Content Fragments), then any Unique constraints should be removed from any Data Types used in the respective Content Fragment Models.
Content fragments are:
Stored as Assets:
Used in the page editor by the Content Fragment component (referencing component):
Accessible using the AEM GraphQL API.
Content Fragments are a content structure that:
To give authors more control of their content, images can be added to and/or integrated with a content fragment.
Assets can be used with a content fragment in several ways; each with its own advantages:
Insert Asset into a fragment (mixed-media fragments)
Visual assets inserted into the content fragment itself are attached to the preceding paragraph. When the fragment is added to a page, these assets are moved in relation to that paragraph when in-between content is added.
Associated Content
See Associated Content for more information.
Assets available from the Assets browser of the page editor
See Assets Browser for more information.
The content fragment assets are made up of the following parts (either directly or indirectly):
Fragment Elements
Fragment Paragraphs
Assets Inserted into a Fragment (Mixed-Media Fragments)
Assets (images) inserted into the actual fragment and used as the internal content of a fragment.
Embedded in the paragraph system of the fragment.
Can be formatted when the fragment is used/referenced on a page.
Can only be added to, deleted from, or moved within, a fragment using the fragment editor. These actions cannot be made in the page editor.
Can only be added to, deleted from, or moved within, a fragment using the Rich Text format in the fragment editor.
Can only be added to multi-line text elements (any fragment type).
Are attached to the preceding text (paragraph).
Assets can be (inadvertently) removed from a fragment by switching to Plain Text format.
Assets can also be added as additional (in-between) content when using a fragment on a page; using either Associated Content or assets from the Assets browser.
Associated Content
This is content external to, but with editorial relevance for, a fragment. Typically images, videos, or other fragments.
The individual assets within the collection are available to be used with the fragment in the page editor, when it is added to a page. This means that they are optional, depending on the requirements of the specific channel.
The assets are associated to fragments by way of collections; associated collections allow the author to decide which assets to use when they are authoring the page.
Optionally you can also add the fragment itself to a collection to aid tracking.
Fragment Metadata
Use the Assets metadata schemas.
Tags can be created when you:
Create and author the fragment
Or later:
Metadata processing profiles do not apply to Content Fragments.
Master
A part of the fragment
Master is accessible in the fragment editor under Variations.
Master is not a variation as such, but is the basis of all variations.
Variations
In-between content:
The in-between content is page content. It is not stored in the content fragment.
To create content fragments, you need:
Content Model
To use your Content Fragments for page authoring, you also need:
Content Fragment Component
A fragment, with its elements and variations, can be used to create coherent content for multiple channels. When designing your fragment, consider what is used and where it is used.
