Authors have a range of options to choose from when organizing a collection of wiki pages.
Used in combination, these give a lot of flexibility.
An effective wiki will use all of these to optimize
content
navigation
These are the two most important aspects of a website.
The most powerful organizing principle is the author's choice of page names. When a search returns a list of pages, their names need to be clear enough to guide a visitor to the right place.
Providing a network of links to other points in the wiki, with or without wiki words, is the primary means of navigating a wiki.
PmWiki requires every page to be a member of a group. A group is like a wiki within a wiki; it can have its own presentation look, security controls and navigation aids. With default configuration, WikiWords are only searched inside the current group, and you use either OtherGroup/MyWikiWord or OtherGroup.MyWikiWord to refer to pages in other groups (see Links).
A collection of pages, either in the same group or across multiple groups, can be designated as a trail. A visitor can move from stop to stop by clicking on next and previous links.
Individual wiki pages can also be grouped by having tags and links to a common "category" page; we say that any pages that link to a common page are in a "category" defined by that page. PmWiki uses the [[!category]] markup as a shorthand to place a page into a category with other pages containing the same markup.
Page lists provide a powerful means of presenting lists of relevant pages, or selection of data from within a page. Lists are template based and are highly customizable.
