6.18.6 Resource OperationDefinition - Detailed Descriptions

Detailed Descriptions for the elements in the OperationDefinition resource.

OperationDefinition
Definition

A formal computable definition of an operation (on the RESTful interface) or a named query (using the search interaction).

Control1..1
OperationDefinition.url
Definition

An absolute URL that is used to identify this operation definition when it is referenced in a specification, model, design or an instance. This SHALL be a URL, SHOULD be globally unique, and SHOULD be an address at which this operation definition is (or will be) published.

Control0..1
Typeuri
Comments

Can be a urn:uuid: or a urn:oid:.

OperationDefinition.version
Definition

The identifier that is used to identify this version of the profile when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the profile author manually and the value should be a timestamp.

NoteThis is a business versionId, not a resource identifier (see discussion)
Control0..1
Typestring
Requirements

There may be multiple resource versions of the profile that have this same identifier. The resource version id will change for technical reasons, whereas the stated version number needs to be under the author's control.

OperationDefinition.name
Definition

A free text natural language name identifying the operation.

Control1..1
Typestring
Comments

Not expected to be globally unique.

OperationDefinition.status
Definition

The status of the profile.

Control1..1

Typecode
Comments

Named queries are invoked differently, and have different capabilities.

OperationDefinition.experimental

Allows filtering of profiles that are appropriate for use vs. not.

OperationDefinition.publisher

OperationDefinition.date
Definition

The date this version of the operation definition was published. The date must change when the business version changes, if it does, and it must change if the status code changes. In addition, it should change when the substantive content of the Operation Definition changes.

Control0..1
TypedateTime
Comments

Additional specific dates may be added as extensions.

OperationDefinition.description
Definition

A free text natural language description of the profile and its use.

Control0..1
Typestring
Comments

This field can be used for things such as why the profile was written, comments about misuse, instructions for clinical use and interpretation, literature references, examples from the paper world, etc. It is not a rendering of the profile as conveyed in Profile.text. This item SHOULD be populated unless the information is available from context.

OperationDefinition.requirements
Definition

Explains why this operation definition is needed and why it's been constrained as it has.

Control0..1
Typestring
Comments

This element does not describe the usage of the operation definition (that's done in comments), rather it's for traceability of why the element is either needed or why the constraints exist as they do. This may be used to point to source materials or specifications that drove the structure of this data element.

OperationDefinition.idempotent
Definition

Operations that are idempotent (see HTTP specification definition of idempotent ) may be invoked by performing an HTTP GET operation instead of a POST.
