Thank you very much for your great web page!

I would like to suggest some more comparison features to you (forgive me if they were already mentioned somewhere else..):

- Metadata support: Does the wiki support rich metadata to characterize the content of the wikipages (tagging, tag clouds, TWiki-Forms etc. instead of only categories). Does it support semantic search functions like faceted navigation? Is it a semantic wiki? Does it allow detailed vertical and hierachial semantic ordering of the pages?

- Page Templates: Does the wiki support page templates which help the user to setup pages easily according to some presettings with no need to start building up the whole page from scratch?

- Is the wiki compliant with the web content accessibility guidelines (WCAG) of the W3C? This is an important questions for disabled users and also for public administration, big companies which have to assure equality for handicaped. Separating content form design is not enough! Accesskeys are nowadays not considered as an accessiblity feature.

- Does the wiki has a support for mobile and handheld devices (see in the matrix: output, handheld-friendly)?

- Please differentiate the language support! Is only the user-interface translated or are all the helpfile translated, too? This makes a big difference! TWiki has a translated interface to German but no German help files at all...

- More infos on access controll (page permission, acls), whether they are role-based, hierachical or flat etc.

As ThomasWaldmann already mentioned somewhere in this forum: Sometimes it doesn't make sense to give just a bulletlist of features to people wanting to find "their" wiki. Rather they should know some background first - some background I could not find on the entire web, so it maybe a good idea to start building a background knowledge base here (Some new menu item WikiBasics next to Home and ChoiceWizward??). E.g. namespaces are well-known, but it's not the only way to solve subdivisioning of a wiki. Please add some infos pages on that, which give the user an overview on different approaches. These separate background information pages could be on:
- Namespaces vs. Wikifarms, Pages vs. Subpages or other concepts of subdivisioning
- Rich Metadata vs. Categories (as small metadata support)
- Datastorage with or without a database behind and their benefits
- Revisons using RCS or not and what's the benefit of that
- Is comment pages worth a comparsion feature? And the ability to have slideshows?? Please discuss here the difference between intranet wikis vs. wikis aiming at documentation purposes and collaborated builidng of books and online enzyklopedias.
- Background infos on programming language. Are some languages slower??? More insecure?? I don't know...

That's it!! Thanks and all the best to you and your great site!! Hope my ideas are of some use to you!!
