Extension DPL

This wiki is the homeplace of two powerful MediaWiki extensions developed and maintained by Gero Scholz.

Dynamic Page List   --   1.6.0

Wgraph

DPL is a report generator for MediaWikis.
It creates lists of articles that match certain criteria. Meta data like author, popularity or date of last update can be added. Contents from articles can be included in the result, based on chapters, templates or special markers in the text.

 category=African Union member states
 nottitlematch=Sudan
 includepage={Infobox Country or territory}:area:population_estimate,%0[100]
 mode=userformat
 addpagecounter=true
 format=,,\n|align=right|%COUNT%\n,
 table=,Country,Area,Poplulation,Text,#hits
 tablerow=align=right|%%,align=right|%%,%%,\n|align=right|%%

Combining the power of DPL and Ploticus we can easily generate a pie chart showing (for example) page hit frequencies. To see that it works live, note the hit count of a country, then click on that country in the above table and come back to the main page. The hit count has changed and the pie has become a little bigger ;-) {{#ploticus:

Wgraph is a graph generator for MediaWikis.
It allows you to define the semantics of a graph in an abstract textual notation called WGL (Wiki Graph Language). You may add hints for layout, but the graph itself is being produced automatically. Wgraph is a powerful visualisation instrument for objects and their relations.
