2.2.2.5.2 Example: DITA map with a simple relationship table

This example illustrates how to interpret a basic three-column relationship table used to maintain links between concept, task, and reference material.

The following example contains the markup for a simple relationship table:

<map>
<!-- ... -->
<reltable>
  <relheader>
    <relcolspec type="concept"/>
    <relcolspec type="task"/>
    <relcolspec type="reference"/>
  </relheader>
  <relrow>
    <relcell>
      <topicref href="A.dita"/>
    </relcell>
    <relcell>
      <topicref href="B.dita"/>
    </relcell>
    <relcell>
      <topicref href="C1.dita"/>
      <topicref href="C2.dita"/>
    </relcell>
  </relrow>
</reltable>
</map>

When the output is generated, the topics contain the following linkage:

A

Links to B, C1, and C2

B

Links to A, C1, and C2

C1, C2

Links to A and B
