Architectural specification : Architectural Specification: Base : DITA markup : DITA metadata
   
DITA metadata
 
Metadata elements
Metadata attributes
Metadata in maps and topics
Cascading of attributes and metadata in a DITA map
Map-to-map cascading behaviors
Reconciling topic and map metadata
Metadata can be applied in both DITA topics and DITA maps. Metadata that is assigned in DITA topics can be supplemented or overridden by metadata that is assigned in a DITA map; this design facilitates the reuse of DITA topics in different DITA maps and use-specific contexts.
