Prolog (metadata) elements

The prolog elements represent the metadata associated with a document. Most of the metadata in a topic prolog can also be authored in a DITA map, in the map's <topicmeta> element.

The primary types of information that you can store in the prolog include:

  • author
  • copyright information
  • critical tracking dates
  • permissions for use/management of the content
  • key words and index terms related to the topic
  • extensive metadata about the content of the document
  • a resourceid that allows a topic to be associated with external resources such as linking to programming components as contextual help
