The predecessor lectio is Management of Wikipages.

Script

At CNM Wiki, a wiki category is the user feature that allows end-users to index wikipages; using this feature, various pages can be grouped and found at the category page.

Category pages belong to special pages.

Categories, a software feature of MediaWiki, provide automatic indexes that are useful as tables of contents.

You can categorize pages and files by adding one or more Category tags to the content text. These tags create links at the bottom of the page that take you to the list of all pages in that category, which makes it easy to browse related articles. Contents

Summary

Each of the pages in the Category namespace represents a so-called category, a grouping of related pages, and contains an index for the pages of its category. For example, this page belongs to "Category:Help". If you open the category page, you will see a link to this page there.

When a page belongs to one or more categories, these categories appear at the bottom of the page (or in the upper-right corner, depending on the skin being used).

The category pages themselves contain 2 parts:

   at their beginning, an optional part may contain text that can be edited, like any other page,
   at their end, an ever present, automatically generated, alphabetical list of all pages in that category, in the form of links. In fact, in the Unicode sort order.

To assign a category to a page, simply add the link "" to the page's wikitext. The usual place to add it is at the bottom of the page.

To link a category page within a page as a normal wiki link (without adding the page to the category), prefix the link name with a colon. For example: Category:Not in this category

A new category can be created before assigning any page to it, in the same way as any other regular page.

Individual wikis may have their own top-level categories, such as Category:Contents in Wikipedia.

For a complete list of all categories which have at least one page, see Special:Categories.

For a complete list of all created/edited categories, including the ones that don't have any pages, see Special:Allpages/Category: (note the colon at the end). Adding a page to a category

To add a page or uploaded file to a category, simply edit the page and add the following text (where Name is the name of the category you want to add it to).

Any number of Category tags may be added to the page and the page will be listed in all of them. Category tags, along with interwiki language links placed in the sidebar, are usually added at the very bottom of the page for the convenience of other editors.

On a categorized page, categories are displayed in the Categories: box strictly in the order they appear in the wikitext.

If $wgUseCategoryBrowser is set to true, under the first list each category is listed again, breadcrumb-style, with all its parent categories, sorted alphabetically. (At least in MediaWiki 1.18.2) if a category is a subcategory of more than one parent, both hierarchies will be listed, but the tagged category will be stripped off all but one of these. This creates the potential for what appear to be duplicate entries if a category with multiple parents and one of its parents are both tagged on a page. For example suppose Maryanne is a subcategory of both Mary and Anne. If a page tags categories Maryanne and Anne then the Category breadcrumbs will show

Anne Anne Mary -> Maryanne

"Anne" appears to be duplicated, but what is meant is

Anne Anne -> Maryanne Mary -> Maryanne

This is a bug, and has been reported in phab:T35614.
