The InterMap is a system for defining links between WikiWikiWeb sites that was first developed by UseMod:UseModWiki and Meatball:MeatballWiki. InterMap links have the form
MapPrefix:Page, 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://www.pmwiki.org/pmwiki2/pmwiki.php/ Cookbook: http://www.pmwiki.org/pmwiki2/pmwiki.php/Cookbook/ Wiki: http://www.c2.com/cgi/wiki? UseMod: http://www.usemod.com/cgi-bin/wiki.pl? Meatball: http://www.usemod.com/cgi-bin/mb.pl? Wikipedia: http://www.wikipedia.com/wiki/ Path:
Thus, PmWiki:Variables becomes 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.
The actual set of InterMap links at any site is defined by the site administrator; for more details, see PmWiki.CustomInterMaps.
