Metadata elements and common attributes

The same metadata elements and many of the same attributes are available in both DITA topic types and DITA map types. The sharing of metadata elements allows the metadata assigned to a topic when it is created to be supplemented or overridden when the topic is included in a collection. The sharing of attributes allows processing behaviors, such as content reuse and conditional processing, to be implemented consistently across both maps and topics.

Common metadata elements
The following metadata elements occur in both maps and topic prologs.
Common attributes
The following attributes are common across most DITA elements.
Topic properties in topics and maps
The properties of a topic (including metadata attributes and metadata elements) can be specified in the topic itself or in references to the topic within maps.You can associate topic metadata with a topic or branch of topics in a map. By default metadata in the map supplements or overrides metadata in the topic. If the lockmeta attribute is set to "no", then the metadata in the map will not take precedence over the metadata in the topic, and conflicts will be resolved in favor of the topic.
