2.1.3.4 DITA addressing
DITA provides a number of facilities for establishing relationships
among DITA elements and between DITA elements and non-DITA resources. All DITA relationships use
the same addressing facilities irrespective of the semantics of the relationship established.
DITA addresses are either direct, URI-based addresses, or indirect key-based addresses. Within
DITA documents, individual elements are addressed by unique IDs specified on the common @id
attribute. DITA defines two fragment identifier syntaxes for addressing DITA elements, one for
topics and elements within maps and one for non-topic elements within topics.
- 2.1.3.4.1 ID attribute
The DITA identity attribute provides a mechanism for identifying content for linking.
- 2.1.3.4.2 URI-based (direct) addressing
Content reference and link relationships can be established from DITA elements using URI references to point directly to targets.
- 2.1.3.4.3 Key-based addressing
The DITA key-reference mechanism provides a layer of abstraction so that the resources addressed by references can be defined globally at the DITA map level instead of locally in each topic.
- 2.1.3.4.4 Summary of addressing elements
This topic contains a table of DITA elements that may be used to link to or address other items. The table describes how and why each element uses the addressing mechanism, rather than defining the element itself.
