This new deliverable version aims to present a plan for the data management, collection, generation, storage and preservation related to BigDataStack activities. In this action, we envision five different types of data:  data provided by the use cases  publications (e.g., conference papers)  public deliverables  open source software  artifacts of research value produced by application executions (e.g., logs, playbooks) The document presents, following the EC template [1], how these different types of data will be collected, who the main beneficiaries are, and how BigDataStack will store them, manage them, and if the project will make them accessible, findable and re-usable. The text continues with the foreseen resources needed for the openness and data to finalize with security and ethical aspects that will be taken into consideration in the context of BigDataStack. This plan may be updated in the M36 version of Technical Reports, having as input the work carried out in the use cases (WP6), the technical work packages (WP2 – WP5) and the dissemination activities (WP7).
