Reverse cross-reference

For a bi-directional link, the reverse cross-reference (or reverse xref) is the component that exists on the link target and refers to the link source. By default, PageSeeder xrefs are bidirectional. This means that, by processing a document, it is possible to know what other documents link to them.

Reverse xrefs are expressed using the <reversexref> element.

Terminology

In link terminology, the source document refers to the document containing the original cross-reference. The target document refers to the document being pointed at.

By definition, reverse cross-references are bidirectional. The forward direction refers to the reference from the source to the target. The reverse direction refers to the reference from the target back to the source.
