Roadmap

Background: In recent years, Wikimedia Foundation's engineering planning has primarily taken place in a combination of internal goals documents and public project-level documentation. The purpose of this page is to establish a practice of sharing holistic engineering goals, initially primarily with a short term horizon, as a public document with open participation.
