Data-aboutThe <data-about> element identifies the
subject of a property when the subject isn't associated with the context in
which the property is specified. The property itself is expressed by the <data>
element. The <data-about> element handles exception
cases where a property must be expressed somewhere other than inside the actual
subject of the property. The <data-about> element
is particularly useful as a basis for specialization in combination with the <data>
element.
Important: Do not use the <data-about>
element to identify the object of a property. The href attribute
of the <data> element serves that purpose.
[edit] Example
The full properties of a cited book can
be maintained conveniently in the prolog:
<topic id="questions">
<title>Questions and answers</title>
<prolog>
<data-about name="book" href="urn:isbn:0156983508">
<data name="title">The World Doesn't End</data>
<data name="author">
<data name="firstname">Charles</data>
<data name="lastname">Simic</data>
</data>
<data name="published" datatype="year">1989</data>
...
</data-about>
...
</prolog>
<body>
...
<lq href="urn:isbn:0156983508">In a forest of question marks ...

[edit] Attributes
| Name
| Description
| Data Type
| Default Value
| Required?
|
| href
| A hyperlink to an external Web page (URL) or other non-DITA resource,
or to another DITA topic in the same file or in another file. The format attribute
identifies the format of the target. Non-DITA targets use standard URL syntax.
DITA topics are targetted as follows:
Target elsewhere in the same file:
href="#topicid"
First topic in different file:
href="filename.dita"
Specific topic in different file:
href="filename.dita#topicid"
If the URL contains an ampersand
character, the ampersand symbol (&) should be used to indicate that
character
| CDATA
| #IMPLIED
| No
|
| format
| The format attribute identifies the format of the resource being
cross referenced. See The format attribute for details
on supported values.
| CDATA
| #IMPLIED
| No
|
| type
| Describes the target of a cross-reference. See The type attribute for
detailed information on supported values and processing implications.
| CDATA
| #IMPLIED (Processed as if the target were of type "topic", or inherited from an ancestor)
| No
|
| scope
| The scope attribute identifies the closeness of the relationship
between the current document and the target resource.
- Set scope to local when the resource is part of the current set of content.
- Set scope to peer when the resource is part of the current set of content but is not accessible at build time.
- Set scope to external when the resource is not part of the current information set and should open in a new browser window.
- See Using the -dita-use-conref-target value for more information on -dita-use-conref-target.
The processing default is local. If no value is
specified, but the attribute is specified on an ancestor within a map or within
the related-links section, the value will inherit from the closest ancestor.
