Okay, I need to create a professional and useful wiki document about "WikiWikiWeb" under the categories of Technology > Software > Open Source. Let me start by understanding what WikiWikiWeb is. From what I remember, it's one of the earliest wikis, created by Ward Cunningham in 1995. The name comes from the Hawaiian word for "quick," which makes sense because it's meant to be a fast way to share information.

First, the structure: H1 title should be "WikiWikiWeb". Then an overview section introducing what it is, its origin, and significance. Next, I need several sections with H2 and H3 headings. Maybe start with the history, then features, technical aspects, impact on open source, and related projects.

For the introduction, I'll mention Ward Cunningham, the year 1995, and the purpose of creating a collaborative space. Then in the history section, detail how it started as a personal project to share software development ideas, leading to the creation of the first wiki. Maybe include some key milestones like the name origin and early adoption.

Features should cover things like simple markup language, easy editing, version control, and linking between pages. Technical aspects could explain the use of Perl, the role of the "Wiki" term, and how it influenced later wikis. The impact on open source might discuss its role in promoting collaboration and community-driven development. Related projects could mention MediaWiki (used by Wikipedia) and other wiki engines.

I need to ensure that all information is accurate. For example, confirming that Ward Cunningham did create the first wiki and that the name comes from the Hawaiian word. Also, check if there are any notable features like the "wiki" term being trademarked or not. I should mention that while the term is a trademark, many wikis exist today.

I need to avoid technical jargon without explanation. For instance, when talking about markup languages, explain that it's a simple syntax for formatting text. Also, make sure each section flows logically and provides enough depth without being too verbose. Since the user wants at least 800 characters, I'll need to elaborate on each point sufficiently.

Check if there are any references or sources to include in the "References" section. Maybe cite Ward Cunningham's original work or articles about the history of wikis. Also, mention related projects like MediaWiki and how they were influenced by WikiWikiWeb.

Make sure the markdown is correctly formatted with H1, H2, H3 headings, bullet points where necessary, and code blocks if there are examples. Avoid using any markdown that's not specified, like tables unless needed. Keep the language clear and professional, suitable for a wiki document.
