`<topicmeta>`

The <topicmeta> element defines the metadata that applies to a topic when it appears in a map. When appropriate, that metadata also applies to the other topics in the map that are contained by the same element that contains the <topicmeta> element. When creating links, <topicmeta> content can also be used to override the title and short description that are used for the link. In addition, it can be used to add index entries to referenced content using the <keywords> element.

The metadata given in a <topicmeta> element is specific to a given context within a map. If a reference to a single resource appears more than once in a map or set of maps, unique metadata can be specified in each instance. For example, the two references to a single resource might specify different navigation titles or search titles, each of which is specific to a single context.

Note: The topic Cascading of metadata attributes in a DITA map in the DITA Architectural Specification provides more information about which metadata elements inside <topicmeta> cascade to other <topicref> elements. In addition, the topic Reconciling topic and map metadata elements provides more information about how metadata specified in the map interacts with metadata specified in each topic.
