The <topicref> element identifies a topic (such as a concept, task, or reference) or other resource. A <topicref> can contain other <topicref> elements, allowing you to express navigation or table-of-contents hierarchies, as well as implying relationships between a containing (parent) <topicref> and its children. You can set the collection-type of a parent <topicref> to determine how its children are related to each other. You can also express relationships among <topicref> elements by using group and table structures (<topicgroup> and <reltable>). Relationships are expressed as links in the output; by default, each participant in a relationship has links to the other participants in that relationship.
You can fine tune the output from your map by setting different attributes on the <topicref> element. For example, the linking attribute controls how a topic's relationships to other topics are expressed as links, and the toc attribute controls whether the topic shows up in TOC or navigation output.
<map title="Bats"> <topicref href="bats.dita" type="topic"> <topicref href="batcaring.dita" type="task"></topicref> <topicref href="batfeeding.dita" type="task"></topicref> <topicref href="batsonar.dita" type="concept"></topicref> <topicref href="batguano.dita" type="reference"></topicref> <topicref href="bathistory.dita" type="reference"></topicref> </topicref> </map>
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. |

A pointer to the resource represented by the <topicref>. See 3.4.2.1 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. |
||||
Introduces one or more global identifiers for a resource referenced from a map. See 3.4.2.2 The keys attribute for details on how to use the keys attribute. |
||||
Keyref provides a redirectable reference based on a key defined within a map. See 3.4.2.3 The keyref attribute for information on using this attribute. |
||||
This attribute is deprecated. It may be removed in the future. |
||||
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. |
