NDH Operations

NDH defines a set of operations to support specific use cases and workflows. These operations are designed to enhance the functionality of FHIR servers implementing the NDH IG and to provide additional capabilities for data manipulation and retrieval.

This operation enables authorized clients to request scheduled, asynchronous NDH data exports with optional resource-type and query filtering, configurable output format and cadence, and lifecycle controls for status tracking, cancellation, and file-retention behavior.
