The Belmont Forum e-Infrastructures and Data Management Collaborative Research Action (CRA) is leveraging worldwide conversations on data sharing e-infrastructures to coordinate open access to transdisciplinary research data generated by Belmont Forum projects. In October 2015, the Belmont Forum adopted a Data Policy and Principles to promote data sharing and reuse among their 25+ international science funding agencies and research partners. These open data principles were recommended in the Community Strategy and Implementation Plan, the report released in 2015 from the scoping phase of the project. Now, work is being undertaken as four independent but interrelated Action Themes to identify, evaluate and adopt global best practices in e-infrastructures and data management for Belmont Forum projects.
