Faq For Categories

What is a category?

Categories are used to group and search for pages.

Page authors can put links to a category or categories on their pages. Then all pages of a given category can then be found by searching for the references to that category (pressing the title of the category page).

A category is a ReverseIndex. For forward indices, see RoadMap.


How do I assign a category to a page?

To mark a page as being part of a particular category you simply include a link to the category name, traditionally at the bottom of the page after a line. This is always a word beginning with Category. For instance, to make your home page part of the CategoryHomePage, you simply end your page with a line and then a link to CategoryHomePage. If you're not sure how to do this, check out the TextFormattingRules.


What categories exist?

See CategoryCategory for a list of all categories.


How do I create a new category?

Copy an existing category page, and change the name. Remember to add a link to CategoryCategory at the bottom of the category page. Edit CategoryCategory to show the newly created category in its proper context. (This shouldn't be too hard to figure out based on similar category names.)


Are there conventions I should know about?

  1. There seems to be a pattern that singular-named pages (eg ..Book) are about specific things while plural-named pages (eg ..Books) are about the general subject or contain lists of the specific.

  2. Categories were originally paired with topics, so one could specify both the form and the content of a page (e.g. a pattern about C++; a discussion about computer research). It was learned from experience, however, that the form of a page is not important enough to use reverse indices for. CategoryLinux and CategoryJava seem to work. For some reason CategoryBook and CategoryHomePage also seem to work. However, CategoryDiscussion and CategoryDefinition seem not to work.

  3. Consider the comments on WhenToAddaCategory.
