Categories do not form a tree

Each Wikipedia article can appear in more than one category, and each category can appear in more than one parent category. Multiple categorization schemes co-exist simultaneously. In other words, categories do not form a strict hierarchy or tree structure, but a more general directed acyclic graph (or close to it, see below). Nevertheless, parts of the category graph will be tree-like, and it may be convenient to think of parts of the category graph as being like multiple overlapping trees. When applying the guidelines above, consider each tree to be independent of the overlapping trees. A person browsing through a hierarchy should find every article that belongs in that hierarchy. This can lead to a good deal of debate as to what the hierarchies actually are. To clarify the structure of the hierarchy and help people browse through it, you can add a classification to each category. For more about this, see Wikipedia:Classification.

Cycles should usually be avoided

Although the MediaWiki software does not prevent cycles (loops), these usually should be avoided. Cycles can be confusing to some readers, they can challenge some automated searching processes and they can grow quite large. For example, in January 2006 a 22-member category cycle was discovered and eliminated.

However, acceptable loops also exist. Self-referencing systems such as the meta- fields naturally create cycles that provide many examples. This type of cycle involves making a category one of its own subcategories. A real-world example of a self-referencing system is “education about education,” such as:

Classification: Education: Social sciences: Academic disciplines: Academia: Education: ...

Another type of cycle involves making two categories subcategories of each other. Loops such as these can be avoided by linking the categories manually to each other by adding "See also:Category:Foo" to each category page. For an example of this see Category:World Trade Center and Category:September 11, 2001 attacks.

The {{catmore}} template

In many cases, a category will have a "main article" or "overview", which describes the subject of that category. In these cases the category and the article often have the same name. If this is the case, do the following:

• Add the "{{catmore}}" tag in the category, after any description of the material covered by that category.
• Arrange for the article to appear at the top of the list of articles in the category, by putting a vertical bar and a space after the category name in the Category: tag (e.g. [[Category:''catname''| ]]).

For such a category/article pair, the guidelines for what other categories the "main article" should be in are still being worked out. Normally articles should not appear both in a category and a "parent" of that category. Some editors feel that an exception should be made for the "main article" of a category—that in many cases the category system makes more sense if each main article appears in some or all of the categories that the equivalent category appears in. Others suggest that the main article should occur only in its like-named category and no others. The latter may be optimal if the category structure is in flux, but it is not optimal for browsing, where the user has to keep bouncing back an forth between the categories of "main" pages and other pages.

If the subject has count, then make the category name plural and create a redirect of that same, plural name, redirecting back to the singular name. For instance City and Category:Cities. That is, create a page called "Cities" and add the line

#REDIRECT [[City]]

This helps to prevent confusion by blocking others from creating a competing page that overlaps in scope and you will be able to use the catmore template without specifying any additional parameters.

In theory, if a main article is categorized correctly in its corresponding cateory, the use of the catmore template is redundant.

Apparently redundant in theory but not in practice. -- Paleorthid 18:17, 3 June 2006 (UTC)
