a web development runtime platform based on the wiki paradigm
DESCRIPTION
When developing a web application, the traditional way is to develop the application from scratch using a general purpose language such as PHP, Grails, Play, Java/JSP, etc. This presentation shows that a next generation wiki (examples based on XWiki: http://xwiki.org) can be used as a web development platform to develop applications on top of it, providing a strong infrastructure scaffolding to building web applications.TRANSCRIPT

Metadata!
• Ability to associate arbitrary data to any wiki page
• 1: Create metadata definition in a wiki page (a.k.a xclass)
• 2: Use it in wiki pages (a.k.a xobjects)
• 3: Use scripting in wiki pages to access it
• Allows application development
