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:
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.
Like other links, you can use the double-bracket syntax to get different link text:
[[M/Meatball:StartingPoints | starting points]] over at Meatballbecomes "starting points? over at Meatball"
[[starting points -> Meatball:StartingPoints]] over at Meatballbecomes "starting points over at Meatball"
If you want to link just to what the intermap says (e.g. http://www.wikipedia.com/wiki/ for Wikipedia), then do
[[W/Wikipedia:. | Wikipedia's main page]], which produces . Note the . (period) after the Map: reference.
The actual set of InterMap links at any site is defined by the site administrator via the page and the local/localmap.txt file; for more details, see .
