The CountingMarker extension provides functionality for monetising a wiki with the Verwertungs­gesellschaft Wort (Copyright collective).


Anyone who is a member of the Verwertungs­gesellschaft Wort (Copyright collective) and operates a wiki faces several problems when they want to participate in the METIS programme, i.e. registering their online texts for monetization.

METIS stands for „Meldesystem für Texte auf Internet­seiten“ (“Reporting System for Texts on Internet Pages”). VG Wort requires a minimum length of the texts as well as a minimum number of article views (“hits”), which must be proven by the installation of “counting pixels” on the article page. For the installation of these pixels you can order “counting markers” from VG Wort, each of which consists of a set of public and private keys and a URL to a counting pixel on a VG Wort server.

A snippet of HTML code on how to include this counter in an HTML page is included. For web pages from the 1980s, which consisted of self-made HTML pages, it is a simple matter to insert this HTML code via copy and paste into the HTML code of the page. But how can these counters be integrated into modern content management systems, which in a very complex way assemble the pages finally delivered to the reader from database queries, templates and skins?

This task, as well as the administration of the counter marks, the assignment of the counter marks to the articles and the annual report to VG Wort are part of the functional scope of this enhancement.


  • Download and place the file(s) in a directory called CountingMarker in your extensions/ folder.
  • Add the following code at the bottom of your LocalSettings.php :
    wfLoadExtension( 'CountingMarker' );
  • Run the update script which will automatically create the necessary database tables that this extension needs.
  •   Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

To users running MediaWiki 1.24 or earlier:

The instructions above describe the new way of installing this extension using wfLoadExtension(). If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'CountingMarker' );, you need to use:

require_once "$IP/extensions/CountingMarker/CountingMarker.php";

Since MediaWiki 1.25 the extension HitCounters should be installed to use the full range of functions. However, there is a basic version in which the HitCounters extension is not required.


The extension was tested with MediaWiki 1.23, 1.25, (1.27), 1.31, (1.33), 1.35.10, (1.36), (1.37), 1.38.4, 1.39.3.


The extension is provided in "de", "en", "es".

Other issuesEdit

There are minor issues, for example the sum of the hits of all articles in v1.25 and v1.27 is displayed incorrectly. However, since this only affects additional statistical information, which does not affect functionality, this is not a problem.

If you run a Wiki family and manage the extensions centrally (via soft links), you have the problem that the Maintenance scripts of this extension are not found. Currently, to solve this problem, these maintenance scripts can be copy & paste into the maintenance folders of the MediaWiki installations.
