`<learningOverviewRef>`

Use a <learningOverviewRef> element to include a topic reference to a learning overview topic as part of a <learningObject> element.

By default, a <learningOverviewRef> is expected to link to a <learningOverview> topic. However, the @href in a <learningOverviewRef> can link to content of any type that you want to use as a learning overview in a learning object. In this way, you can structure any existing DITA content as a learning object, and then take advantage of the learning-specific processing available for building and packaging that content for delivery in a learning system or learning context.

Attributes

The following attributes are available on this element: Universal attribute group, Link relationship attribute group (with narrowed definitions of @href and @format, given below), Attributes common to many map elements (without the @collection-type attribute, and with a narrowed definition of @chunk, given below), Topicref element attributes group, outputclass, @keys, and @keyref.

@href: A pointer to the resource represented by the <topicref>. See The href attribute for detailed information on supported values and processing implications. References to DITA content cannot be below the topic level: that is, you cannot reference individual elements inside a topic. References to content other than DITA topics should use the @format attribute to identify the kind of resource being referenced.
@format: On this element, the @format attribute has a default value of "dita", because it usually links to DITA learning topics. If linking to something other than DITA, set the @format attribute as described in The format attribute.
@chunk: On this element, the @chunk attribute has a default value of "to-content", which causes the current branch of content to be published as a single unit. See Chunking for more information and for details on other supported values.
