__NOTOC__
  
DPL is a MediaWiki extension which creates ''lists of articles that match certain criteria''. Articles are listed by name; ''meta data'' like  popularity or last access date can be added. And there are powerful mechanisms to ''extract content'' from the articles and show it as part of the list.

== Example ==
 
There are some articles on ''fictitious coutries'' (this is also the name of their common category). They all use a template named "Country" which receives facts like ''capital''. The template produces a small table and a link to the country list we want to generate. There are chapters on religion and history in most of the articles.
 
We show how to create a sortable wikitable list of those articles which gives some excerpts of the contents.
 
{{Sortable Tables}}
 
 
 
DPL can be used as a mediawiki parser '''extension''', which means that a special DPL tag is used:
 
<pre><nowiki>
 
<DPL>
 
   category=Fictitious country
 
   includepage={Country},#History,#Religion
 
  includemaxlength=50
 
  addpagecounter=true
 
 
   mode=userformat
 
   mode=userformat
  listseparators=\n{|class=sortablewikitable id=123 \n!Country \n!Official Name \n!Capital \n!Dial Code \n!History \n!Religion \n|-,\n|-\n|[[%PAGE%]] (%COUNT%)\n,\n,\n|}
 
  secseparators=,\n|,,
 
</DPL>
 
</nowiki></pre>
 
 
We select articles by category and explain that we want to see contents from the template "Country" and from two chapters. We truncate the excerpts. We create a sortable table which contains article name and access frequency in the first column and the content pieces in the other columns. Note that at the end of truncated contents you will find a small arrow which links directly to the chapter from where the contents was taken. The formatting for the template varibales is being done in a special template which is by convention named "Country dpl". This template is very simple; it only presents the values for name, capital and dial code as columns of a table.

 +
</div></center>

Combining the power of DPL and [[mw:Extension:Ploticus|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 ;-)

This wiki is the homeplace of three powerful MediaWiki extensions developed and maintained by Gero Scholz.
Currently we run MediaWiki 1.13 with page caching enabled.

A universal report generator for MediaWikis
A light-weight approach to semantic wiki
A graph generator based on aiSee

Dynamic Page List (DPL)
DocTypes
Wgraph

Dynamic Page List   --   2.0

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.

Country Area Population Text #hits
Cameroon 475,442 16,323,000
     ..→</small>

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 Demo

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.
