There are several advanced services related to the rendering of content fragments. To use these services, the resource types of such components must make themselves known to the content fragments framework.
This is done by configuring the OSGi Service - Content Fragment Component Configuration.
This information is required when:
It is recommended to use the Core Components.
If you do not need the advanced services described below, you can ignore this configuration.
When you are extending or using the out-of-the-box component(s), it is not recommended to change the OSGi configuration.
You can write a component from scratch that uses the Content Fragments API only, with no advanced services. However, in such a case, you will have to develop your component so that it handles the appropriate processing.
Therefore, it is recommended to use the Core Components.
The services that require the registration of a component are:
If you need one or more of these features, then (typically) it is easier to use the out-of-the-box Advanced Services, instead of developing them from scratch.
The configuration needs to be bound to the OSGi service Content Fragment Component Configuration:
See OSGi Configuration for further details.
The OSGi configuration is:
||The resource type to register; for example,
||The name of the property that contains the reference to the fragment; for example,
||The name of the property that contains the name(s) of the element(s) to render; for example,
||The name of the property that contains the name of the variation to render; for example,
For some functionality your component will have to adhere to predefined conventions. The following table details the properties that need to be defined, by your component, for each paragraph (i.e.
jcr:paragraph for each component instance) so that the services can detect and process them correctly.
A string property that defines how paragraphs are to be output if in single element render mode.
A string property that defines the range of paragraphs to be output if in single element render mode.
||A boolean property that defines if headings (for example,
As an example, see the following (on an out-of-the-box AEM instance):
dam.cfm.component.resourceType="core/wcm/components/contentfragment/v1/contentfragment" dam.cfm.component.fileReferenceProp="fragmentPath" dam.cfm.component.elementsProp="elementName" dam.cfm.component.variationProp="variationName"
