2.11.1 2.46.1 Scope and Usage

This special resource type is used to ~~pass information into and back from an~~ represent the operation (whether invoked directly from REST or within a messaging environment). It is not persisted or allowed to be referenced by other resources except as described below. Because Parameters does not reflect a persistent healthcare-related entity but rather just a collection of data passed into or out of an operation, there is generally no need to have a RESTful endpoint at which such instances can be created, updated, queried, etc. However, there are a few limited cases where this can make sense: Parameters instances can be stored to record inbound and/or outbound information in support of an AuditEvent instance Parameters instances might be persisted either on their own or as part of a Bundle to support documentation of examples for an ImplementationGuide and/or test data for a TestScript Technically, Parameters is a specialization of Resource and as such could potentially appear anywhere that 'Resource' is permitted request and could be referenced anywhere an element has an unconstrained type of Reference. For example, it could appear in FHIR documents, as contained resources, referenced by extensions, in elements like Observation.focus, etc. However, such use is prohibited unless the element containing the Resource or Reference type explicitly indicates that Parameters is permitted. If there is a requirement to exchange arbitrary collections of data elements, this need should typically be met using Basic . response.

2.11.2 2.46.2 Boundaries and Relationships

This special resource has no other use than for operation parameters, and there is no RESTful end-point associated with it. For further information, see the operations page.

OperationDefinition defines constraints on the Parameters resource instances that are used to convey the inputs and outputs of the ~~operation.~~ operation

A parameter must have ~~one and~~ only one of (value, resource, part)

(part.exists() and value.empty() and resource.empty()) or (part.empty() and (value.exists() xor resource.exists()))

Note: for technical compatibility reasons, the Parameters resource inherits from Resource , but since the parameter exchange format has no end-point and/or persistence, it never has an id, a versionId, or a lastUpdated. The other features of Resource (tags, profiles, security labels, language etc.) may have use when operations are executed.

2.11.4.2 2.46.3.2 Names and Identifiers

The following rules apply to name and identifier uniqueness within a Parameters resource:

Parameter Names Parameter names can be repeated at any level. The meaning of duplicate parameter names - and whether it is valid to repeat any given parameter name - depends on the context. Typically, operation definitions define what parameters can be used, and whether they can repeat. The order of parameters with different names is not considered significant

Resources Resources in parameter.resource do not need to be unique, though the ~~interpretation~~ interpretaton of non-unique resources, or different versions of the same resource, may be ambiguous in cases where the parameter names do not clearly differentiate the purpose of the parameter. For additional commentary, see the notes about about resource ~~uniqueness~~ uniquness in Bundles , though be aware that those rules do not apply to the Parameters resource unless the fullUrl extension is present on parameters with resources.

Internal References When internal references are resolved in a resource in a parameter.resource, the resolution stops at parameter.resource. This allows resources to appear more than once in a Parameters resource, and also means that resources cannot reference content in another resource using an internal reference (except for references inside contained resources )

References When resolving references in resources, the applicable Operation Definition may specify how references may be resolved between parameters. If a reference cannot be resolved between the parameters, the application should fall back to ~~its~~ it's general resource resolution methods
