The logical id of the measure to analyze. The server must know the measure (e.g. it is defined explicitly in the server's measures)

A canonical reference to a measure. The server must know the measure (e.g. it is defined explicitly in the server's measures

The version of the measure to analyze

A business identifier of the measure to be analyzed. The server must know the measure and the identifier must resolve unambiguously to a single measure on the server.

The start of the measurement period. In keeping with the semantics of the date parameter used in the FHIR search operation, the period will start at the beginning of the period implied by the supplied timestamp. E.g. a value of 2014 would set the period start to be 2014-01-01T00:00:00 inclusive

The end of the measurement period. The period will end at the end of the period implied by the supplied timestamp. E.g. a value of 2014 would set the period end to be 2014-12-31T23:59:59 inclusive

Any additional input parameters for the measure. Parameters defined in this input will be bound by name to parameters defined in the measure library (or referenced libraries). Parameter types are mapped to CQL as specified in the Using CQL section of this implementation guide. If a parameter appears more than once in the input Parameters resource, it is represented with a List in the input CQL. If a parameter has parts, it is represented as a Tuple in the input CQL.

Specifies a version to use for a system, if the measure or value set does not already specify which one to use. The format is the same as a canonical URL: [system]|[version] - e.g. http://loinc.org|2.56

Edge Case: Specifies a version to use for a system. If a measure or value set specifies a different version, an error is returned instead of the package. The format is the same as a canonical URL: [system]|[version] - e.g. http://loinc.org|2.56

Edge Case: Specifies a version to use for a system. This parameter overrides any specified version in the measure and value sets (and any it depends on). The format is the same as a canonical URL: [system]|[version] - e.g. http://loinc.org|2.56. Note that this has obvious safety issues, in that it may result in a value set expansion giving a different list of codes that is both wrong and unsafe, and implementers should only use this capability reluctantly. It primarily exists to deal with situations where specifications have fallen into decay as time passes. If the value is override, the version used SHALL explicitly be represented in the expansion parameters

Specifies an asset-collection library that defines version bindings for code systems referenced by value set(s) or other artifacts used in the artifact. When specified, code systems identified as depends-on related artifacts in the measure or dependent libraries have the same meaning as specifying that code system version in the system-version parameter.

Specifies whether to follow known dependencies of the artifact as part of the analysis, recursively (default = true)

Specifies whether to follow known components of the artifact as part of the analysis, recursively (default = true)

The result of the requirements operation is a module-definition Library that returns the computed effective requirements of the artifact.
