 This paper presents a framework with 10 components to deliver a data management process for storing and managing data used in marine spatial planning, MSP, in Ireland, including a data process flow and recommended solution architecture that includes a central data catalogue and spatial storage system. The framework aims to maximize the reuse potential of any data set within an MSP context by offering formal and considered assessments of data such as suitability and readiness and exploring how data can be published externally to potential consumers. The process ensures data lineage is optimized by carrying information about the origin and processing applied to the data, evaluates the quality and relevance of geospatial data sets for MSP decisions in Ireland and was piloted in the National Marine Planning Framework for Ireland with ongoing feedback from public consultation.
