This week was about polishing Roadblock, a Node.js based application to measure community metrics 📊.

At one point, we wanted endpoints to measure Zalando’s contributions to external Open Source projects, and external contributors contributing to Zalando’s projects. 🙄

This is when I was eager to how a Contributor differed from a Collaborator. 🤷

Contributor: A person from the outside not on the core development team of the project that wants to contribute some changes to a project.

Collaborator: A person on the core development team of the project and has commit access to the main repository of the project.
