The document briefly outlines the concept of an IOC Data Architecture proposed to optimise connections between existing IOC elements that would strengthen delivery of ocean data for multiple services and applications. The IOC Data Architecture Concept Proposal (IOC/INF-1550) contains details on this architecture and how the unique IOC set of assets will connect and integrate to deliver something much more powerful than the sum of its parts. The Assembly is being asked to approve the IOC Data Architecture concept and Terms of Reference for the Working Group on the development of the IOC Data Architecture, which are annexed to the proposed decision under this item.
