Module 11 Introduction Wikis provide users with a shared electronic notebook that can grow as large as needed. Contributors can easily start a new page in the notebook, or add information to a page that’s already there. Importantly, they can also go back to see previous versions of any page, see who made each change (and why), and easily restore any page to any of its previous versions. In this module we will explore wiki’s facilities for editing articles in more detail. The goals are: to examine a wiki’s mechanisms for supporting collaboration ; to describe the mechanisms for managing articles’ histories ; to understand the potential for revision conflicts that arise from concurrent updates and how to respond to such conflicts; to reinforce the importance of cooperation when working in collaborative environments. More specifically, by the end of the module, you will be able to: e xamine an article’s editing history and revert an article to a previous version; respond appropriately to a conflicting update.

CS 100 Module 11 11.2 11.0 Revising Wiki Articles © 2009, University of Waterloo It rarely happens that the first version of a document requires no changes. This is especially true in a collaborative environment, where colleagues work together to describe some people, places, policies, proceedings, or phenomena. Therefore the facilities to edit articles without constraints and to examine each step of an article’s evolution are important features for productivity. The material in this module expands on the text found in MediaWiki on pages 17-22 and 72-73.

CS 100 Module 11 11.3 11.1 Editing an Article The essence of wikitext was described in the previous module. Much like KompoZer provides a point-and-click interface to mark up a document with HTML, MediaWiki provides an interface to introduce wikitext. After clicking on the edit tab for a page, you see the existing wikitext displayed in an edit panel. Above that panel is a toolbar that provides several buttons for inserting wikitext. For example, highlighting some text and then clicking the second button, inserts two single quotes (wikitext to indicate italics) around the highlighted text. Alternatively, clicking on that button with no text highlighted inserts new text ( '' Italic text '' ) at the current cursor position, after which you can replace the highlighted words by the text you wish to be rendered in italics. Notice that the editor is not a WYSIWYG editor: the text you highlighted or entered is not displayed in italics on the edit page. Nevertheless, the interface provides a convenient way to enter some commonly used wikitext. At the bottom of the edit page, you can find a Summary box in which you should always enter a brief explanation of the changes you have made: You can also find a row of three buttons and two additional options. You should always choose Show preview before choosing Save page , so that you can ensure that your updates will produce the article in the way you
