The InterMap (also called InterWiki in some other wikis) is a system for defining links between WikiWikiWeb sites that was first developed by UseMod:UseModWiki and Meatball:MeatballWiki. The method is to use a word that stands for a path that is defined. InterMap links have the form MapPrefix:PagePath, where the host prefix is converted to a partial URL based on entries in the site's intermap.txt and localmap.txt files.

The default intermap.txt distributed with PmWiki (in the scripts/ directory) includes the following InterMap entries:

 PmWiki:     http://pmwiki.org/wiki/PmWiki/ 
 Cookbook:   http://pmwiki.org/wiki/Cookbook/ 
 Wiki:       http://c2.com/cgi/wiki? 
 UseMod:     http://usemod.com/cgi-bin/wiki.pl? 
 Meatball:   http://usemod.com/cgi-bin/mb.pl? 
 Wikipedia:  http://wikipedia.com/wiki/ 
 PITS:       http://pmwiki.org/PITS/ 
 Path:

You can map your own prefixes in your local page Site.InterMap ?.

Thus, "PmWiki:Variables" becomes "http://pmwiki.org/wiki/PmWiki/" + "Variables," a link to the PmWiki.Variables page on the official PmWiki web site, Wiki:FrontPage is a link to the front page of the first WikiWikiWeb, and Wikipedia:Stonehenge takes you to the Wikipedia article about the famous megaliths in England.

Like other links, you can use the double-bracket syntax to get different link text:

* [[Meatball:StartingPoints | starting
points]] over at Meatball
* [[starting points ->
Meatball:StartingPoints]] over at
Meatball

If you want to link just to what the intermap says (e.g. http://wikipedia.com/wiki/ for Wikipedia), then do [[Wikipedia:. | Wikipedia's main page]], which produces Wikipedia's main page. Note the . (period) after the Map: reference.

The special Path: InterMap entry can be used to create "relative urls" in links.

The actual set of InterMap links at any site is defined by the site administrator via the Site.InterMap ? page and the local/localmap.txt file; for more details, see PmWiki.CustomInterMaps.
