Metadata qualification elements

These elements qualify the topic for processes such as flagging, filtering, or retrieval.

The metadata elements apply to an entire topic, and can also be used in a map to apply metadata to multiple topics at a time. Metadata elements can expand on the values used in metadata attributes. (See metadata attributes.) For example, the audience element in a topic's prolog can define an audience in terms of type, job, and experience level, and give it a name; when there is content within the topic's body that applies only to that audience, that content can identify its audience by the same name used in the prolog.

When metadata is expressed in a map, it supplements any metadata expressed in the topics it references. When metadata in a map and a topic conflict (for example, both define a publisher), by default the value in the map takes precedence, on the assumption that the author of the map has more knowledge of the reusing context than the author of the topic.

audience
The type, job, experience level, and other characteristics of the reader for the topic. Many of these characteristics have enumerated values, but the enumeration can be extended through associated attributes. For instance, the audience type enumeration can be extended through an othertype attribute. The audience element can elaborate values used by audience attributes.
category
A classification of the topic content. Such classifications are likely to come from an enumerated or hierarchical set. This element is equivalent to both Dublin Core Coverage and Dublin Core Subject.
keywords
Terms from a controlled or uncontrolled subject vocabulary that apply to the topic.
prodinfo
The definition of the product or platform for the topic. The prodinfo element can elaborate values used by the product and platform attributes.
othermeta
A name-value pair specifying other metadata about the topic.
