Content Fragment Templates

Some Content Fragment functionality requires the application of AEM 6.4 Service Pack 2 (6.4.2.0) .
Content fragment models are now recommended for creating all your fragments.
Content fragment models are used for all examples in We.Retail.
Templates are selected when creating a content fragment. They provide the new fragment with the basic structure, element(s) and variation. The templates used for content fragments are subject to the Granite Configuration Manager.
The out-of-the-box templates are held under:
  • /libs/settings/dam/cfm/templates
You can create your site-specific templates for content fragments under:
  • /apps/settings/dam/cfm/templates
    The location for overlaying out-of-the-box templates or providing customer-specific, application-wide templates that are not intended to be extended/changed at runtime.
  • /conf/global/settings/dam/cfm/templates
    The location for instance-wide customer-specific templates that need to be changed at runtime.
The order of precedence is (in descending order) /conf , /apps , /libs .
You must not change anything in the /libs path.
This is because the content of /libs is overwritten the next time you upgrade your instance (and may well be overwritten when you apply either a hotfix or feature pack).
The recommended method for configuration and other changes is:
  1. Recreate the required item (i.e. as it exists in /libs ) under /apps
  2. Make any changes within /apps
The basic structure of a template is held under:
conf
  global
    settings
      dam
        cfm
          templates
            <template-name>
              ...

With the specific structure being:
+ <template-name>
    - jcr:primaryType
    - jcr:title
    - jcr:description
    - initialAssociatedContent
    - precreateElements
    - version 
    + elements
        - jcr:primaryType
        + <element-name>
            - jcr:primaryType
            - jcr:title 
            - defaultContent 
            - initialContentType 
            - name 
        ... + other element definitions
    + variations
        - jcr:primaryType 
        + <variation-name>
            - jcr:primaryType 
            - jcr:title 
            - jcr:description
            - name 
        ... + other variation definitions 

More details about the nodes and their properties are:
  • Template
Name Type Value
< template-name > nt:unstructured This node is the root for each template. It is mandatory and should have a unique name.
jcr:title
String
required
The title of the template (displayed in the Create Fragment wizard).
jcr:description
String
optional
A text that describes the purpose of the template (displayed in the Create Fragment wizard).
initialAssociatedContent
String[]
optional
An array with paths to collections that should be associated to a newly created content fragment by default.
precreateElements
Boolean
required
true , if the subassets representing the elements (except the master element) of the content fragment should be created when the content fragment is created; false if they should be created "on the fly".
Note : currently this parameter has to be set to true .
version
Long
required
Version of the content structure; currently supported:
Note : currently this parameter has to be set to 2 .
  • Elements
Name Type Value
elements
nt:unstructured
required
Node that contains the definition of the elements of the content fragment. It is mandatory and needs to contain at least one child node for the Main element, but can contain [1..n] child nodes.
When the template is used the elements sub-branch is copied to the model sub-branch of the fragment.
The first element (as viewed in CRXDE Lite) is automatically considered to be the main element; the node name is irrelevant and the node itself does not have a special significance, apart from the fact that it is represented by the main asset; the other elements are handled as sub assets.
  • Element Name
Name Type Value
< element-name > nt:unstructured This node defines an element. It is mandatory and should have a unique name.
jcr:title
String
required
The title of the element (displayed in the fragment editor's element selector).
