Users and applications will migrate from maintaining private data (e.g., data kept within system specific storage) to making data available in shared data spaces. These shared spaces will provide repositories where users and applications can submit, or post, data assets to the communities of in space. The shared spaces will provide storage and management services. Data spaces of the ADSE will be maintained, secured, and staged as necessary to support NATO’s missions. Data that is posted to shared spaces will be advertised via its associated metadata and will be discoverable across the Alliance.
