Definition

An InterWiki link can be used for referring to a Wiki page located in another Wiki system, and by extension, to any object located in any other Web application, provided a simple URL mapping can be done.

At the extreme, InterWiki prefixes can even be used to simply introduce links to new protocols, such as tsvn: used by TortoiseSvn.

Link Syntax

<target_wiki>(:<identifier>)+

The link is composed by the targeted Wiki (or system) name, followed by a colon (e.g. MeatBall:Note that, as for InterTrac prefixes, '''InterWiki prefixes are case insensitive'''.

The target Wiki URL is looked up in the InterMapTxtmodelled after MeatBall:InterMapTxt.

In addition to traditional InterWikiTrac supports parametric InterWiki URLs: identifiers $1, $2, ... in the URL will be replaced by corresponding arguments. The argument list is formed by splitting the page identifier using the ":" separator.

Examples

If the following is an excerpt of the InterMapTxt page:

= InterMapTxt =
== This is the place for defining InterWiki prefixes ==
Currently active prefixes: [[InterWiki]]
This page is modelled after the MeatBall:InterMapTxt page.
In addition, an optional comment is allowed after the mapping.

Then,

• MoinMoin:InterWikiMap should be rendered as MoinMoin:InterWikiMapand the ''title'' for that link would be "InterWikiMap in MoinMoin"
• Trac-ML:4346 should be rendered as Trac-ML:4346 and the ''title'' for that link would be "Message 4346 in Trac Mailing List"
