Use the SQID Issues page on github to report issues and to find out if your issue is already known or even being worked on.


You do not normally need to install this yourself, since it is a Web application that you can use in your browser. Developers who want to change the code should have a local copy that runs though. This is farily easy:

  • Download the files. The Web application is in the src folder, which should be made accessible through your local web server.
  • Get some data. You can copy the example json data files from src/data/exampleData to src/data/ to get started. You can update these files by running the Python scripts under helpers/python from this directory, but this will not recreate all statistics. You can also download most recent updated json files
  • Optionally recreate all statistics. The program to do this is in the branch "sqid-helper" of Wikidata Toolkit. The main code is in SchemaUsageAnalyzer.java. The code is invoked by using the command-line client (running the client will show a help message that includes this action).
