Use a learningOverviewRef element to include a topic reference to a learning overview topic as part of a learningObject.
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.
When you include a reference to a DITA topic that is not learningOverview, change the type attribute to match the type of topic being referenced.
|learningBookmap, learningMap||( (topicmeta) (optional) )|
|Name||Description||Data Type||Default Value||Required?|
|navtitle||Specifies the title of the topic as it will appear in the navigation or tables of contents that are generated from the map. Beginning with DITA 1.2, the preferred way to specify the navigation title in a map is with the navtitle element, available inside the topicmeta element.||CDATA||#IMPLIED||No|
|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.||CDATA||#IMPLIED||No|
|query||This attribute is deprecated. It may be removed in the future.||CDATA||#IMPLIED||No|
|copy-to||Use the copy-to attribute on the
<topicref> element to provide a different file name
for a particular instance of the topic in the map (for example, to separate out
the different versions of the topic, rather than combining them on output). The
links and navigation associated with that instance will point to a copy of the
topic with the file name you specified.
Use the <linktext> and <shortdesc> in the <topicref>'s <topicmeta> to provide a unique name and short description for the new copy.
|type||The topic type of the map reference.||CDATA||learningOverview||IMPLIED|
|topicref-atts attribute group (collection-type, processing-role, type, scope, locktitle, format, linking, toc, print, search, chunk)||A set of related attributes. See topicref-atts, topicref-atts-no-toc, and topicref-atts-without-format attribute groups.|
|univ-atts attribute group (includes select-atts, id-atts, and localization-atts groups)||A set of related attributes, described in univ-atts attribute group|
|global-atts attribute group (xtrf, xtrc)||A set of related attributes, described in global-atts attribute group|
|class, outputclass, keyref||Keyref provides a redirectable reference based on a key defined within a map. See The keyref attribute for information on using this attribute. Class and outputclass are described in Other common DITA attributes|
