Hi
I am wanting to download and install Wiki Software on an AIX server and have no idea which one or where to start ; preferably Open Source - anyone any ideas?
Thanks
The OS basically has no mean to run a wiki on. It more depends on a webserver to reach it, sometimes a database in the backround (I'd prefer those that don't need one though) and a script language like php or perl etc.
Here you can check which might be most suitable for your needs and even compare them etc. very nice site:
EDIT: dokuwiki is small, fast, easy and you can set permissions and stuff.
Thanks, we have an apache web server running already if that helps? We use other SAS web technology and basic java script etc.
We've got an apache web server that we currently use for basic html/java/javascript and SAS intrnet processing - I thought the right wiki application would allow us to use the apache server (I know we will need a mysql database or something too)
Thanks
No, as I said only some wikis use databases in the background. Many use flatfile repositories.
Basically you have your Apache being capable to process the language the wiki is written in, may it be php, perl or whatever.
Then you usually just have to share the directory where the wiki is place with it's index.html index.php or index.pl or whatever and that's it.
Depends solely which wiki you decide to give a go.
mediawiki is the most used and bloated wiki out there. is the one used in wikipedia and similars.
other wikis are to rigid and/or ugly 
<--- WARNING, personal opinion.
you could check plone too. is more like a content manager, but can be used to upload files and cerate rich text pages.
