subjectRole

Darwin Information Typing Architecture (DITA) Version 1.2

The <subjectRole> element, when used within a <subjectRel> element, contains a set of subjects that are related to other subjects in the same row of the current <subjectRelTable>. By default, no relationship is defined between multiple subjects in the same <subjectRole> element. When used within the <subjectRelHeader>, the <subjectRole> element defines the category of subject or relationship provided by that column.

Example

The subject relationship table in this example establishes environmentFor relationships between operating systems and applications. Based on the subjectRole element, subjects in the first column are operating systems which are the environment for an application, while subjects in the second column are applications that run in that environment. For a user interested in content about the operating system, content about the applications may also be relevant.
