Editorial commentary

Where a narrative DMP communicates intent to a human reviewer, the machine-readable expression communicates to other systems. It encodes the same decisions but as typed properties with identifiers, dates, and controlled vocabularies. The RDA DMP Common Standard is the most widely adopted schema for this expression.
