Data

The Data section describes the nature, structure, and representation of the data that constitutes the body or payload of the service's messages, i.e., the data shared between service providers and consumers. The Data section captures bibliographic and location information for relevant data definition documents, including XML Schemas, Data Model Diagrams, or other descriptive documents. NOTE: NSRR allows service publishers to store these documents in the registry; see the Service Documents section for information about uploading and downloading these and other documents.
