Profiling with a Subject Scheme Map

A subject scheme map allows you to create custom profiling values and to manage the profiling attribute values used in the DITA topics without having to write a DITA specialization.

<topicref href="test.ditamap" format="ditamap" type="subjectScheme"/>

A profiled value should be a short and readable keyword that identifies a metadata attribute. For example, the audience metadata attribute may take a value that identifies the user group associated with a particular content unit. Typical user values for a medical-equipment product line might include therapist, oncologist, physicist, radiologist, surgeon, and so on. A subject scheme map can define a list of these audience values.

EXAMPLE:

The following is an example of content from a subject scheme:

<subjectScheme>
  <!-- Pull in a scheme that defines audience user values -->
  <subjectdef keys="users">
    <subjectdef keys="therapist"/>
    <subjectdef keys="oncologist"/>
    <subjectdef keys="physicist"/>
    <subjectdef keys="radiologist"/>
    <subjectdef keys="surgeon">
      <subjectdef keys="neuro-surgeon"/>
      <subjectdef keys="plastic-surgeon"/>
    </subjectdef>
  </subjectdef>
  <!-- Define an enumeration of the audience attribute, equal to
       each value in the users subject. This makes the following values
       valid for the audience attribute: therapist, oncologist, physicist,
       radiologist, surgeon, neuro-surgeon and plastic-surgeon. -->
  <enumerationdef>
    <attributedef name="audience"/>
    <subjectdef keyref="users"/>
  </enumerationdef>
</subjectScheme>
