1.11.5 Resource Resource - Detailed Descriptions

Detailed Descriptions for the elements in the Base Resource Definitions.

Resource
Definition

This is the base resource type for everything.

Control1..1
Resource.id
Definition

The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.

Control0..1
Typeid
Summarytrue
Comments

The only time that a resource does not have an id is when it is being submitted to the server using a create operation. Bundles always have an id, though it is usually a generated UUID.

Resource.meta
Definition

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content may not always be associated with version changes to the resource.

Control0..1
TypeMeta
Summarytrue
Resource.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.

Control0..1
Typeuri
Is Modifiertrue
Summarytrue
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 as much as possible.

Resource.language
Definition

The base language in which the resource is written.

Control0..1
BindingLanguage : Required: IETF language tag (A human language.)
Typecode
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).

Meta
Definition

The metadata about a resource. This is content in the resource that is maintained by the infrastructure. Changes to the content may not always be associated with version changes to the resource.

Control1..1
Summarytrue
Meta.versionId
Definition

The version specific identifier, as it appears in the version portion of the URL. This values changes when the resource is created, updated, or deleted.

Control0..1
Typeid
Summarytrue
Comments

The server assigns this value, and ignores what the client specifies, except in the case that the server is imposing version integrity on updates/deletes.

Meta.lastUpdated
Definition

When the resource last changed - e.g. when the version changed.

Control0..1
Typeinstant
Summarytrue
Comments

This value is always populated except when the resource is first being created. The server / resource manager sets this value; what a client provides is irrelevant.

Meta.profile
Definition

A list of profiles StructureDefinitions that this resource claims to conform to. The URL is a reference to StructureDefinition.url.

Control0..*
Typeuri
Summarytrue
Comments

It is up to the server and/or other infrastructure of policy to determine whether/how these claims are verified and/or updated over time. The list of profile URLs is a set.

Meta.security
Definition

Security labels applied to this resource. These tags connect specific resources to the overall security policy and infrastructure.

Control0..*
BindingAll Security Labels: Security Labels from the Healthcare Privacy and Security Classification System. (Extensible)
TypeCoding
Summarytrue
Comments

The security labels can be updated without changing the stated version of the resource The list of security labels is a set. Uniqueness is based the system/code, and version and display are ignored.

Meta.tag
Definition

Tags applied to this resource. Tags are intended to be used to identify and relate resources to process and workflow, and applications are not required to consider the tags when interpreting the meaning of a resource.

Control0..*
BindingTags: Codes that represent various types of tags, commonly workflow-related; e.g. "Needs review by Dr. Jones"
TypeCoding
Summarytrue
Comments

The tags can be updated without changing the stated version of the resource. The list of tags is a set. Uniqueness is based the system/code, and version and display are ignored.
