  3. 3. Web 2.0 Web 2.0 aka Web (with some tidying up)• It was supposed to be like that since day one• Web Services vs Software Development• Tons of Information that needs to be sorted, filtered, evaluated and finally delivered to the end users.

  7. 7. Wikis and what’s cool about them• Mainly open source w.k.a “Free”• Fast and secure• Easy to setup (for admins) and easier to use (for end users)• Ideal for collaboration• Versioning support• User roles• Tracking - Auditing
  8. 8. Wikipedia a bit of history• Once upon a time there was Nupedia. An encyclopedia populated and reviewed by experts. Founded by Jimmy Wales and Larry Sanger.• Wikipedia started as a complementary project to support Nupedia providing “draft” articles for further review.• Quickly it overtook Nupedia and became very very popular.• English version reached 500.000 articles in 2005, 1 million in 2006 and now has over 3 million articles. Has nearly 9.000.000 pages views per... HOUR!• Available in 271(!) languages. Greek version was over 46.000 articles. In total there are more than 14.000.000 articles!
  9. 9. Wikipedia how it works• In January 2001 there was UseModWiki written in Perl by Clifford Adams.• Then in January 2002 Magnus Manske developed a Wiki written in PHP...• ...supported by MySQL.• 6 months later is was rewritten by Lee Daniel Crocker, and was named MediaWiki.• Since then new features are added such as support for Templates, and Extensions.
