0. Parameters | |
Definition | This resource is a non-persisted resource used to pass information into and back from an operation. It has no other use, and there is no RESTful endpoint associated with it. |
Short | Operation Request or Response |
Comments | The parameters that may be used are defined by the OperationDefinition resource. |
Control | 0..* |
Is Modifier | false |
Summary | false |
2. Parameters.implicitRules | |
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc. |
Short | A set of rules under which this content was created |
Comments | Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc. |
Control | 0..1 |
Type | uri |
Is Modifier | true because This element is labeled as a modifier because the implicit rules may provide additional knowledge about the resource that modifies it's meaning or interpretation |
Primitive Value | This primitive element may be present, or absent, or replaced by an extension |
Summary | true |
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) |
4. Parameters.parameter | |
Definition | A parameter passed to or received from the operation. |
Short | Operation Parameter |
Control | 10..* |
Type | BackboneElement |
Is Modifier | false |
Summary | true |
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) inv-1: 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())) )inv-1: 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()))) |
Slicing | This element introduces a set of slices on Parameters.parameter . The slices areUnordered and Closed, and can be differentiated using the following discriminators: |
6. Parameters.parameter.modifierExtension | |
Definition | May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself). |
Short | Extensions that cannot be ignored even if unrecognized |
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone. |
Control | 0..* |
Type | Extension |
Is Modifier | true because Modifier extensions are expected to modify the meaning or interpretation of the element that contains them |
Summary | true |
Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions. |
Alternate Names | extensions, user content, modifiers |
Invariants | ele-1: All FHIR elements must have a @value or children (hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (extension.exists() != value.exists()) |

Comments | Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute). | ||||
