XWiki offers both a generic platform for developing collaborative applications using the wiki paradigm and projects developed on top of it. First generation wikis are used to collaborate on content. Second generation wikis (a.k.a Structured and Applications Wikis) can be used to create collaborative web applications. XWiki can be used either as a first generation wiki or a second generation one. XWiki is the next generation wiki, a generic web development platform for collaborative applications. As such its use cases are diverse: collaborative intranet, knowledge base, CMS, competitive intelligence, public debate, collaborative creation of school courses, web site creation, etc. See below a list of projects based on XWiki.
