{description: 'This statement defines the expected capabilities of a system that aggregates data from multiple Data Source actors before measure evaluation and then plays the role of a Data Source once aggregation is complete. An example would be a state public health agency aggregating data from all facilities in the state before using those data to produce a MeasureReport containing bed capacity data for the entire state. When FHIR enabled, a Data Aggregator acts as a [US Core Server](http://hl7.org/fhir/us/core/STU6.1/CapabilityStatement-us-core-server.html) when playing the role of a Data Source after aggregation. During aggregation, the Data Aggregator acts similar to the SANER options for aggregation, but implements its own CapabilityStatement due to the incompatibilities between DEQM and SANER.', package_name: hl7.fhir.us.safr, name: SafrCapabilityStatementDataAggregator, type: null, package_version: 1.0.0-ballot, class: requirements, kind: requirements, url: 'http://hl7.org/fhir/us/safr/CapabilityStatement/SafrCapabilityStatementDataAggregator', version: 1.0.0-ballot}
