Anybody knows any knowledge base open source?

I want to build a web-based knowledge base system for our call center. To save some development time, I am looking for a open source. Does anybody know any good one out there?

Thanks in advance,

Tony

• How about one of the many wikis?

  Kenny: I've used FlexWiki & ScrewTurn.

  someone else with RepPower to edit my post added this.
  Wikipedia is powered by MediaWiki.

  Joel Coehoorn : beat my but 20seconds. deleting my nearly identical answer

  Olaf : http://en.wikipedia.org/wiki/List_of_wikis

  acrosman : Actually, I'd suggest: http://en.wikipedia.org/wiki/List_of_wiki_software

• http://www.kbpublisher.com/

  Joel Coehoorn : looks interesting, but fails the open source requirement.

• ScrewTurn Wiki

• Also, consider GForge.

• I have used phpMyFAQ and found it to be very good.

  John Boker : i too have used it and find it to be acceptable

• I heard of RTFM (The RT FAQ Manager). Never used it, however.

• In addition to MediaWiki that was mentioned by Kenny, you might also look at MoinMoin.

  Choosing between MediaWiki and MoinMoin can be a bit tough. Here are some points to consider:

  MediaWiki

  Pros:

  • Made for wikipedia, thus is very mature and scalable.

  • Fairly easy to set up.

    Cons:

  • Made soley for wikipedia. Thus it can be a bit of a pain to customize how you like it.

  MoinMoin

  Pros:

  • Very mature software.

  • Huge amount of plugins and third party modules available.

    Cons:

  • Can be a pain to install.

  There are a huge amount of other wikis available, but those are the main two I would consider.

• Thanks everyone!

• MindTouch is open source and has a KB add-on. Lots of public sites that use their commercial version (Mozilla, RightScale, Intuit, Palm) and I've seen in their developer community that most of them started w/the open source ver.
