The 1st Periodic Delivery Report informs about the achievement of milestones and other outputs produced in the CESSDA SAW project in the first 8 months of its duration. Each work package in the project produced a definitive statement of outputs reached by the end of the first reporting period. It also serves as the first documentation of the activity progress and collaboration between different beneficiaries and Linked Third Parties in this project. It defines the current status of the SaW work plan and gives overview of the future planned activities over the course of the project.
