Well, back in 1999 when I was a web developer at RagingBull, we used a wiki system as a content creation and management backend to our website front-end. Starting in 2005, I used MediaWiki as the platform to organize operations, development and technology services at OASIS. Most recently, I've been deploying MediaWiki in my new role at the IIC at Harvard. I'm here to share some of that experience with you. The great thing about sharing knowledge; like sharing free software; is...

== Using it - Why? ==
Wikis are immensely popular and come in many flavors. It was late 2006 to early 2007 when 'wiki' reached it's zenith as a buzzword in the news.<ref>[http://www.google.com/trends?q=wiki Google Trends for keyword wiki]</ref> But wikis have not faded into the sunset like last years fashion. I'll point out a few reasons why you should choose MediaWiki as your wiki platform.
The growth curve of MediaWiki is exponential. The quality of the software is excellent.
Does your wiki have [http://wikimania2006.wikimedia.org/wiki/Main_Page conferences]?

In 2007 it was announced that a WYSIWYG editor would be built for MediaWiki. Wikia (Jimmy Wales' for-profit venture) started work on it. It still isn't ready for prime time. Note that I had to patch a minor bug to get it to work and even then, it did funny things with my article (wanted to collapse a line-break between template tag and next line resulting in a space being inserted prior to the next line, resulting in preformatted text rendering for that line.

== Administering it ==
</source>
One good practice is to have some sort of text version or other backup of your wiki in case the machine, webserver, or database that the system depends on is down. One As an administrator, you can use the dumpBackup.php script found in the <code>maintenance</code> directory of you MediaWiki installation. Something like the following in a system [[cron]] would be good:<source lang="bash">/usr/bin/php /var/www/phase3/maintenance/dumpBackup.php --current --output=file:/var/backups/example.com/`date +%F`-wiki.text.export.txt</source> As a user, one tool that can come in handy is [[Special:Wiki2XML]] <ref>http://tools.wikimedia.de/~magnus/wiki2xml/README, see also [[Format_conversion]]</ref>
You can mass Another useful tool to the Administrator is the bulk image importer. To import all the screenshots that I used at the start of this presentation, I did the following:<source lang="bash">php importImages.php --user=Freephile --comment='Set of screenshots of sites using MediaWiki ' ~/Desktop/mediawiki/snaps/</source>Note how using a Category tag in the comment will automatically place the imagesin the Category specified.
== Developing it ==
# Extensions
# Conversion of existing wikis and documents [[Format conversion]]
# [[API]]s are very useful to developers. [[mw:Developers|MediaWiki Developers]] can use the [[mw:API|Application Programming Interface for MediaWiki]] which gets exposed at /api.php, as well as the http://meta.wikimedia.org/wiki/Pywikipediabot framework which helps to automate manipulation of the wiki.

==== Timelines ====

MIT's SIMILE project Timeline is integrated into Semantic MediaWiki
* e.g. http://semanticweb.org/wiki/Events
=== Database ===
The MediaWiki software uses a MySQL database backend to store content and other data. The [[MediaWiki/Sql]] article offers a couple helpful queries; whereas [[mw:Manual:Database_access]] covers this area more completely including info on API functions and wrappers.
== Getting it, Installing it ==
MediaWiki is developed using a Continuous Integration approach meaning that their trunk is tested and running in production http://www.mediawikiMediaWiki.org/wiki/Version_lifecycle
