topicSubjectRow

The <topicSubjectRow> is a grouping element that contains one row of a subject table. It contains topic references in the first column, and relates those references to the subjects in each following column.

Example

The topic subject table below classifies topics with goals for retrieval and with operating systems for filtering. The map makes use of definitions in a subject scheme map, defined separately.

            <subjectdef href="performanceGoal.dita" keys="performance"/>

Topic subject table

The following <topicSubjectTable> classifies several topics according to subjects in the previous map. As with any <topicSubjectTable>, the first column is used to specify topics. In this specific example, the second column is used to specify a goal, based on the "goal" subject in the header. The third column is used to specify an operating system. Based on those definitions, the following classifications are made by this table:

The topics "Configuring cron for efficient startup" and "Allocating raw storage" are each classified by the goal of "performance"; in addition, they are classified by the operating systems "linux" and "unix.
The topics "Analyzing web logs for service issues" and "Detecting denial-of-service attacks" are each classified by the goal of "reliability"; in addition, they are classified by the operating systems "linux", "unix", and "windows".
No relationship is defined between subjects in the table, meaning that this table does not define any relationship between the goal of "performance" and the operating systems "linux" or "unix".

A table view of this <topicSubjectTable> might look as follows. This is only one of many possible views; to aid in understanding the example, the content topics in the first column are displayed using only their titles, and related subjects are displayed using only their keyref attribute value.

task	goal	os
Configuring cron for efficient startup Allocating raw storage	performance	linux unix
Analyzing web logs for service issues Detecting denial-of-service attacks	reliability	linux unix windows
