xwiki: a web development runtime platform
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, Java/JSP, etc. This presentation will show that a second 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 much if not all the needed infrastructure scaffolding.The advantages are similar to those of using an application sever. However whereas an application server offers technical services only, a wiki platform offers higher level services such as content management, rendering, storage, WYSIWYGeditor, user management, and a lot more.Not only are these services offered, you can develop using them in your traditional IDE or in the runtime, directly in wiki pages. This allows developing web applications extremely quickly with a fast turnaround time, which is perfect for adhoc web application development.TRANSCRIPT

Why use XWiki?
Copyright (c) Vincent Massol - 2011
Pros (1/2)
• Iterative, Need-based development
• Continuous Delivery
• Online immediately (no deployment needed)
• Works from day one, immediate feedbacks
Copyright (c) Vincent Massol - 2011
Pros (2/2)
• Work collaboratively on creating applications
• Designers can style while devs create logic
• Open source
• Strong and meritocratic community
Copyright (c) Vincent Massol - 2011
Cons• Save code in SCM
• ... but SVN Application
• Low integration with existing dev tools
• ... but XEclipse
• ... but WebDAV
• Not an official standard
• Higher “risk”, less trained devs, etc
