The CI/CD landscape is rich and diverse, with tools like Keptn, Tekton and Argo that offer opinionated solutions to specific problems. Organizations rely on combinations of these tools to address their automation requirements, but they lack a way to orchestrate, monitor and measure their overall workflow. There is a real need for interoperability and standardization in the CI/CD space: solving this problem is the mission of the Events SIG at the CD foundation. This session introduces the work of SIG Events in establishing a dictionary, a "lingua franca" for tools to understand each other.
