(:nl:)(:Summary: PmWiki structural support for page organization:) 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.
:Wiki Word: 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.
:Wiki Page: A page with text (and images), where the text can contain for instance WikiWords that automatically becomes a link to another WikiPage.
:Wiki Group: 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).
:Wiki Trails: 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.
:Categories: 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.
: : The shortcoming of categories is that categories do not distinguish between the declaration of a category ([[!structure]]) and the link to a category ([[Category/Structure]]).
:Page text variables: A newer and more powerful concept than Categories, pages can use one of more page text variables to store page attributes. These can the be used in page lists.
:Page lists: 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.
:Include other pages: The capability to include parts of other pages also provides a flexible means of sharing content between pages.
:Search: Being able to search is a fundamental requirement of a website. In PmWiki search, like pagelists is both powerful and highly customizable. (:nl:)
