Parts of pages, not only entire pages, can be addressed.
Some wikis support syntax for manually creating HTML “<A NAME=…>” anchors. This is somewhat more useful on Wikis than elsewhere, since new anchors can be added by people other than the author.
Something like this is necessary to support links in a TableOfContents.
Each paragraph (or other structural element - footnote, section, figure, etc.) has a unique identifier, known as a NID (node identifier). (These were called SIDs - Statement Identifiers - in NlsAugment.) Ideally NIDs are permanent, but they are temporary in some implementations. For convenience there are also HIDs - hierarchical identifiers - that are specific to a particular version of a document and specify a logical location within the document (e.g. “paragraph 2 of section 3”).
PurpleWiki supports permanent NIDs. BR MoinMoin automatically generates fragment ids for all headings.
Arbitrary regions can be referenced (character spans, or parts of images). The Eprints archive server supports this.
