Advancing Open Science through Trusted Data Repository Intersections at the World Data System

The World Data System (WDS), a member of the International Science Council, serves a membership of over 150 trusted data repositories and related organizations. It builds on the data sharing legacy of World Data Centers that were initiated seven decades ago. Governed by a Scientific Committee, the WDS consists of an International Program Office (WDS-IPO) based in Oak Ridge, Tennessee, USA, and an International Technology Office (WDS-ITO) based in Victoria, BC, Canada. The WDS mission is to enhance the capabilities, impact, and sustainability of our member data repositories and data services. In this presentation, we outline the 2025 to 2027 Action Plan objectives, highlighting activities and collaborations that are underway or planned to progress open science, integrated data infrastructures and FAIR/CARE/TRUST Principles.
