Wikis are part of the technologies included in Web 2.0. They can be very useful for sharing information within an organization. Here at IBM wikis are becoming very popular.
MediaWiki is the PHP-based wiki engine that is used by wikipedia. In fact, it was originally written for Wikipedia. It is available as open-source from http://www.mediawiki.org. The current release is version 1.12.0.
It seems to me that IDS is particularly well suited to support a wiki. It is a high-performance database engine that is scalable and required little administration. Also, with the clustering capabilities of IDS 11, It provides a very scalable platform for a wiki.
Why mention all this? Because I created modules to support IDS as a database engine under MediaWiki. It requires IDS 11 since it also uses the Basic Text Search (BTS) DataBlade to provide searching capabilities. I still consider this "beta" code and it will require additional modifications but it works.
