Structured wiki

From semanticweb.org

So are called some wikis (or wiki engines) which include certain database features. This direction of extending a basic wiki engine is similar to semantic wiki, and thus, structured wikis and semantic wikis might have similar uses.

[edit] Other wikis with simple database features

The following wikis haven't been probably called structured wikis (neither semantic wikis), but add categorization and database-like features to basic wiki engines:

• MediaWiki has categories.
• DynamicPageList2 is a MediaWiki extension which allows the generation of lists from complex queries on categories (e.g., union, intersection). (The queries to categories functionality of this extension is a step in the direction of Semantic MediaWiki extension.)
• OmegaWiki (former WiktionaryZ) builds a specialized database into MediaWiki.
