Example: conref redirection
This section is non-normative.
The @conkeyref
attribute enables authors to share DITA topics that reuse
content. It also enables map authors to specify different key
definitions for common keys.
In this scenario, Acme produces content for a product that is also resold through a business partner. When the DITA content is published for the partner, several items must be different, including the following:
- Product names
- Standard notes that contain admonitions
Simply using the @conref
attribute would not be possible for teams that use a
component content management system where every DITA topic is addressed by a globally-unique
identifier (GUID).
-
Authors reference the reusable content in their topics by using the
@conkeyref
attribute, for example:<task id="reusable-product-content"> <title><keyword conkeyref="reuse/product-name"/> prerequisites</title> <taskbody> <prereq><note conkeyref="reuse/warning-1"/></prereq> <!-- ... --> </taskbody> </task>
-
Authors create two different topics; one topic contains elements appropriate for Acme, and the other topic contains elements appropriate for the partner. Note that each reuse topic must use the same element types (or compatible specializations) and values for the
@id
attribute. For example, the following reuse file is appropriate for use by Acme:<topic id="acme-reuse"> <title>Reuse topic for Acme</title> <body> <note id="warning-1">Admonitions for Acme</note> <p><keyword id="product-name">Acme product name</keyword></p> <!-- ... --> </body> </topic>
The following reuse file is appropriate for use by the OEM partner:
<topic id="oem-reuse"> <title>Reuse topic for OEM partner</title> <body> <note id="warning-1">Admonitions for partner</note> <p><keyword id="product-name">OEM product name</keyword></p> <!-- ... --> </body> </topic>
-
The two versions of the DITA maps each contain different key definitions for the key name "reuse". (This associates a key with the topic that contains the appropriate reusable elements.) For example:
Figure 1. DITA map for Acme <map> <!-- ... --> <keydef keys="reuse" href="acme-reuse.dita"/> <!-- ... --> </map>
Figure 2. DITA map for OEM partner <map> <!-- ... --> <keydef keys="reuse" href="oem-reuse.dita"/> <!-- ... --> </map>
When each of the DITA maps is published, the elements that are referenced by
@conkeyref
will use the reuse topic that is referenced by the
<keydef>
element in the map. The product names and warnings will be
different in the output.
