Allies will develop a concept for an Alliance data sharing ecosystem for defence and security, with an initial focus on selected thematic areas, e.g. geospatial and location data, climate, information environment assessment, energy, space or maritime data, at the non-classified level, guided by the data requirements to support the Alliance priority use cases in NATO’s AI Strategy and Data Exploitation Framework Strategic Plan. Through this ecosystem, Allies will establish a data sharing imperative and will share data in selected policy areas, in line with NATO’s Principles of Responsible Use. The concept will enable data from Allies, the NATO Enterprise and Allied industry and research partners to be shared, collaboratively labelled, connected, and exploited. The concept should leverage existing efforts under NATO’s AI Strategy and Data Exploitation Framework Policy, support the MDO concept, and link to related strategic deliverables, such as Data-centric Governance and Alliance Cloud environment activities.
