This slide deck provides case studies of five organizations piloting a minimum viable proof-of-concept dataspace focused on the exchange of distributed OA book usage metrics. Organizational demographics, pilot implementations and outcomes are described. Anticipated returns for participation in a full dataspace deployment are noted and referenced in the companion OAEBUDT Pilot Evaluation and Return on Investment Analysis report. This work was made possible through the "OAeBU Data Trust: Advancing to Launch by Developing IDS Governance Building Blocks" project grant funded by The Mellon Foundation.
