Common metadata elements

The following metadata elements occur in both maps and topic prologs.

Many of the DITA metadata elements map to Dublin Core metadata (http://dublincore.org/), with the exception of Dublin Core elements such as title, which maps to the DITA <title> element.

1. Publication metadata elements
   These elements provide standard information about the topic as a publication.
2. Management metadata elements
   These elements provide a basis for managing the publication process for topics.
3. Metadata qualification elements
   These elements can be used to provide additional information about a topic, and may be used in conjunction with conditional processing attributes to provide more information about the attribute values.
