The D1.2 H2IOSC Access Coordination and Management Procedures/Report illustrates the activities of the Access Coordination and Management Unit (A1.2), which centrally prepared and managed four Trans-national access (TNA) and National Access (NA) calls for proposals. The aim was to ensure the highest degree of integration in accessing the wider range of tools, services and facilities offered by the H2IOSC Cluster. The report highlights the results achieved, describes the TNA/NA process designed to support access, and details the implementation, promotion and coordination of the calls. The successful execution of the four TNA/NA calls was made possible through strong collaborative work with the Infrastructure Manager, Project Coordinator, and Infrastructure Coordinators, as well as with the Service Providers, who were responsible for feasibility evaluation and service access, and the External Advisory Board (EAB), in charge of the evaluation process. Metrics for evaluating the outcomes were also defined and collected. This version of the report covers all achievements from the 4 TNA/NA calls.
