Detailed Descriptions for the elements in the EventDefinition resource.

EventDefinition
Element IdEventDefinition
Definition

The EventDefinition resource provides a reusable description of when a particular event can occur.

Short DisplayA description of when an event can occur

Invariants
Defined on this element
cnl-0Warning Name should be usable as an identifier for the module by machine processing applications such as code generationname.exists() implies name.matches('^[A-Z]([A-Za-z0-9_]){1,254}$')
EventDefinition.url
Element IdEventDefinition.url
Definition

An absolute URI that is used to identify this event 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 an authoritative instance of this event definition is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the event definition is stored on different servers.

Short DisplayCanonical identifier for this event definition, represented as a URI (globally unique)
Cardinality0..1
Typeuri
Requirements

Allows the event 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.

Invariants
Defined on this element
cnl-1Warning URL should not contain | or # - these characters make processing canonical references problematicexists() implies matches('^[^|# ]+$')
EventDefinition.identifier
Element IdEventDefinition.identifier
Definition

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

Short DisplayAdditional identifier for the event definition
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 event definition outside of FHIR, where it is not possible to use the logical URI.

EventDefinition.version
Element IdEventDefinition.version
Definition

The identifier that is used to identify this version of the event definition when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the event 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.

Short DisplayBusiness version of the event definition
NoteThis is a business versionId, not a resource version id (see discussion)
Cardinality0..1
Typestring
Summarytrue
Comments

There may be different event 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 event definition with the format [url]|[version]. The version SHOULD NOT contain a '#' - see Business Version.

EventDefinition.versionAlgorithm[x]
Element IdEventDefinition.versionAlgorithm[x]
Definition

Indicates the mechanism used to compare versions to determine which is more current.

Short DisplayHow to compare versions
Cardinality0..1
Terminology BindingVersion Algorithm (Extensible)
Typestring|Coding
[x] NoteSee Choice of Datatypes for further information about how to use [x]
Summarytrue
Comments

If set as a string, this is a FHIRPath expression that has two additional context variables passed in - %version1 and %version2 and will return a negative number if version1 is newer, a positive number if version2 and a 0 if the version ordering can't be successfully be determined.

EventDefinition.name
Element IdEventDefinition.name
Definition

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

Short DisplayName for this event definition (computer friendly)
Cardinality0..1
Typestring
Requirements

Support human navigation and code generation.

Summarytrue
Comments

The name is not expected to be globally unique. The name should be a simple alphanumeric type name to ensure that it is machine-processing friendly.

EventDefinition.date
Element IdEventDefinition.date

Cardinality0..1
TypedateTime
Alternate NamesRevision Date
Summarytrue
Comments

The date is often not tracked until the resource is published, but may be present on draft content. Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the event definition. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

See guidance around (not) making local changes to elements here.

EventDefinition.publisher

EventDefinition.useContext
Element IdEventDefinition.useContext
Definition

The content was developed with a focus and intent of supporting the contexts that are listed. These contexts may be general categories (gender, age, ...) or may be references to specific programs (insurance plans, studies, ...) and may be used to assist with indexing and searching for appropriate event definition instances.

Comments

It may be possible for the event definition to be used in jurisdictions other than those for which it was originally designed or intended.

DEPRECATION NOTE: For consistency, implementations are encouraged to migrate to using the new 'jurisdiction' code in the useContext element.
