The CMS Open Source Program Office developed various tools that can automate detecting, adding, and updating metadata to repositories.
repo-scaffolder is a tool for creating repositories that adhere to repository hygiene standards. It provides file templates detailing project information, contributing guidance, maintainer roles, community involvement, and project metadata.
For repositories created using repo-scaffolder, the tool can assist with adding code.json to the repository. Navigate to your project's .github directory and run the following cookiecutter command. You will be asked questions about the project in order to collect and store this metadata in code.json.
cookiecutter . --directory=codejson
