|Author for DITA / DITA Profiling / Conditional Text|
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 is 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.
Following is the sample content of the test.ditamap 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> </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 --> <enumerationdef> <attributedef name="audience"/> <subjectdef keyref="users"/> </enumerationdef> </subjectScheme>
When you edit a DITA topic in the Text mode or in the Author mode, Oxygen XML Author plugin collects all the profiling values from the Subject Scheme Map that is referenced in the map currently opened in the DITA Maps Manager. The values of profiling attribute defined in a Subject Scheme Map are available in the Edit Profiling Attribute dialog regardless of their mapping the Conditional Text preferences page.
Now let us consider we have the following fragment in a topic:
<p audience="neuro-surgeon">Some text.. </p>
When you define a DITAVAL filter you can exclude for instance anything which is surgeon:
<val> <prop action="exclude" att="audience" val="surgeon"/> </val>
Then if you transform the main DITA Map specifying the DITAVAL filter file in the transformation scenario the p element should be excluded from the output. So excluding the surgeon audience excludes also the neuro-surgeon and plastic-surgeon from the output. More details about how hierarchical filtering and Subject Scheme Maps should work are found in the specification:http://docs.oasis-open.org/dita/v1.2/os/spec/langref/subjectScheme.html#subjectSchemehttp://docs.oasis-open.org/dita/v1.2/os/spec/langref/subjectScheme.html%23subjectScheme
