-Here are the InterWiki prefixes known on this Trac site:
-[[InterWiki]]
+''(since [milestone:0.10])''
 
-Note that the InterWiki prefixes for trac:
- * trac-changeset:1234 and trac-ticket:567 
-can be rewritten using the trac:InterTrac syntax, as:
- * trac:changeset:1234 and trac:ticket:567
-or even more concisely, as:
- * [T1234] and #T567.
+== 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.
+
+== Link Syntax ==
+
+{{{
+<target_wiki>(:<identifier>)+
+}}}
+
+The link is composed by the targeted Wiki (or system) name,
+followed by a column (e.g. {{{MeatBall:}}}),
+followed by a page specification in the target.
+Note that, as for InterTrac prefixes, InterWiki prefixes are case insensitive.
+
+The target Wiki URL is looked up in a the InterMapTxt wiki page, 
+modelled after
+[http://www.usemod.com/cgi-bin/mb.pl?InterMapTxt MeatBall:InterMapTxt].
+
+In addition to traditional InterWiki links, where the target
+is simply ''appended'' to the URL, 
+Trac 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.
