archive of kek-online.de

The Kommission zur Ermittlung der Konzentration im Medienbereich (KEK), collects and publishes shareholding information about german newspapers, radio and tv stations and online services.

This archive stores a daily snapshot of their undocumented json web API. The files are:

• docs/data/media.json (from https://medienvielfaltsmonitor.de/api/v1/media/)

  This is a list of all medias in the KEK database.

• docs/data/shareholders.json (from https://medienvielfaltsmonitor.de/api/v1/shareholders/)

  That's the list of all shareholders and operators/publishers.

  All media and shareholders are identified by UUIDs and more detailed information for each entity is available in the following files:

• docs/data/media/

  • 5be1a6b1-0a0b-42ac-b845-1914e17d572f.json (from https://medienvielfaltsmonitor.de/api/v1/media/5be1a6b1-0a0b-42ac-b845-1914e17d572f)

To build the complete graph of shareholders and media, you need to parse the individual files in docs/data/shareholders/ or load the docs/data/graph.dot file. The dot format for graphs is widely supported, for example by:

• The Graphviz commandline tools
• The igraph library for R, Python, Mathematica and C
• The vis.js library for Javascript
• The Gephi application for Mac, Windows and Linux

From my experience, the fastest way of layouting the graph is Gephi: Load the dot file, select "ForceAtlas2" in the "Layouter" and "run" the thing.
