- Guidelines for a dCoC data governance process to ensure the integrity of the DCM and situational-awareness at each transfer point within the dCoC.
- Suggestions regarding metadata management policies and compliance with good practices for non-repudiation digital log, ensuring a standard data structure for data management and auditing

It will be complemented by other specific parts, which give more detailed guidelines for related services, such as the specification of BPMN processes for data governance within the dCoC.
