Detailed Descriptions for the elements in the ActivityDefinition resource.

ActivityDefinition
Element IdActivityDefinition
Definition

This resource allows for the definition of some activity to be performed, independent of a particular patient, practitioner, or other performance context.

Cardinality0..*
TypeDomainResource
Invariants
Defined on this element
adf-0Warning Name should be usable as an identifier for the module by machine processing applications such as code generationname.matches('[A-Z]([A-Za-z0-9_]){0,254}')
ActivityDefinition.url
Element IdActivityDefinition.url
Definition

An absolute URI that is used to identify this activity definition when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which at which an authoritative instance of this activity definition is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the activity definition is stored on different servers.

Cardinality0..1
Typeuri
Requirements

Allows the activity definition to be referenced by a single globally unique identifier.

Summarytrue
Comments

Can be a urn:uuid: or a urn:oid: but real http: addresses are preferred. Multiple instances may share the same URL if they have a distinct version.

The determination of when to create a new version of a resource (same url, new version) vs. defining a new artifact is up to the author. Considerations for making this decision are found in Technical and Business Versions.

In some cases, the resource can no longer be found at the stated url, but the url itself cannot change. Implementations can use the meta.source element to indicate where the current master source of the resource can be found.

ActivityDefinition.identifier
Element IdActivityDefinition.identifier
Definition

A formal identifier that is used to identify this activity definition when it is represented in other formats, or referenced in a specification, model, design or an instance.

NoteThis is a business identifier, not a resource identifier (see discussion)
Cardinality0..*
TypeIdentifier
Requirements

Allows externally provided and/or usable business identifiers to be easily associated with the module.

Summarytrue
Comments

Typically, this is used for identifiers that can go in an HL7 V3 II (instance identifier) data type, and can then identify this activity definition outside of FHIR, where it is not possible to use the logical URI.

ActivityDefinition.version
Element IdActivityDefinition.version
Definition

The identifier that is used to identify this version of the activity definition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the activity definition author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence. To provide a version consistent with the Decision Support Service specification, use the format Major.Minor.Revision (e.g. 1.0.0). For more information on versioning knowledge assets, refer to the Decision Support Service specification. Note that a version is required for non-experimental active assets.

NoteThis is a business versionId, not a resource version id (see discussion)
Cardinality0..1
Typestring
Summarytrue
Comments

There may be different activity definition instances that have the same identifier but different versions. The version can be appended to the url in a reference to allow a reference to a particular business version of the activity definition with the format [url]|[version].

ActivityDefinition.name
Element IdActivityDefinition.name
Definition

A natural language name identifying the activity definition. This name should be usable as an identifier for the module by machine processing applications such as code generation.

Cardinality0..1

Terminology BindingRequest priority (Required)
Typecode
ActivityDefinition.doNotPerform
Element IdActivityDefinition.doNotPerform
Definition

Set this to true if the definition is to indicate that a particular activity should NOT be performed. If true, this element should be interpreted to reinforce a negative coding. For example NPO as a code with a doNotPerform of true would still indicate to NOT perform the action.
