MediaWiki - Further plugins which make MediaWiki better

In Semantic Media Wiki - making MediaWiki better I already briefly explained how the Semantic Media Wiki and the Semantic Forms plugin make the MediaWiki software better. But since I am using these, I also come over some other plugins which are also pretty great:

• Parser Function - Introduces logic by provideing functions like if, ifexists, switch, etc.  
• Arrays - Creates an additional set of parser functions that operate on arrays
• Semantic Result Formats - Additional formats to present results of semantic queries, like timeline, chart or tag cloud.
• Data Transfer - Enables you to create pages out of csv or xml files by filling the data into templates. Great way to import big amounts of data.
