Here are the more common terms and concepts we use to talk about wikis:



Anonymous User

A wiki visitor that has not logged in. From the wiki's perspective, it could be anybody.


A file on the wiki associated with a wiki page.


A user that has edit privileges on a given wiki section. Usually editing, attaching files, and choosing labels (in addition to viewer privileges) are assigned to authors.

Blog Post

see News


A posting on a page, separate from the page content. Comments may be threaded, which allows "conversations" to take place in the context of a page, similar to "forum" or "bulletin board" web sites.


Text, images, supporting files, and formatting information. See Page and Wiki Markup

Content Area

see Space


A network technology that can be used to control which computers can access your wiki.


Settings or content that affects the entire wiki.


A collection of users. Users can belong to more than one group. Groups are the most common "user element" on which permissions are defined.

Home Page

The default landing page for the wiki. Spaces also have default landing (home) pages.


A clickable image or piece of text on a web page that navigates to a new page, causes an action, or downloads a file.


Special purpose pages within a space that are identified by a date in addition to the page title. Also called blog posts.


A single web page of content in the wiki. Pages are organized into spaces and are identified by their title. No two pages in the same space can have the same title. In addition, pages are arranged in a parent-child hierarchy.


Settings that specify what a given user or group is allowed to do on the wiki.


A file that is loaded into the wiki to provide custom behavior. Plug-ins are available from


or can be custom built. Plug-ins must be evaluated for compatibility with each other as well as the specific version of the wiki software.

Rich Text Editor (also RTE)

A word-processor-like content editor that hides Wiki Markup from the user. Like a word processor, more complicated content formats can be challenging for both the user and the RTE. In some cases, editing the wiki markup directly can be easier.


Pages in the wiki that share the same parent.


A collection of topic-related pages (content areas). Spaces are also the most common "wiki unit" on which permissions are defined.


A plug-in that defined a special look-and-feel and custom navigation and other features for a wiki. Themes can apply globally or to individual spaces. Here are some examples of custom themes.


A set of pages defined by a given page plus its children (and their children, and so on).


A login account on the wiki, identified by a username (login), which defines the user's name, email address, and other preferences. Users are usually added to groups to simplify permissions management.


A user that has read-only privileges on a given wiki section. Usually, posting comments is allowed as well.

Wiki Markup

Notation added to text that provides formatting instructions and special features available in the wiki. The word markup supplies the M in HTML.
