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
