There are wiki functions that work on pagesets (there will be some development there):

• listing
• searching
• evaluations
• calculations

• implicit
• index (all pages)
• top pages (1th level pages)
• search results (pages that contain...)
• page context (pages edited e. g. last week)
• ...
• relativ to a page
• Descendants
• Children
• Grandchildren
• Uncles
• Father
• Grandfather
• Sisters
• Forefathers
• specified
• by list (pagenames, Urls, InterMap?, ...)
• by a wildcard system (to be constructed)
• by categories
• ...

Note that there are alternative way to describe/resolve page-sets, useful if two or more wikis are involved. The most portable, and most likely to break horribly if a wiki moves, is to use the canonical URLs of the sites themselves. If you're lucky, the site is on a domain with unbreakable URLs that will work forever. Alternatively, you could use standard InterMap? notation if that makes sense. -- ChrisPurcell
