Page versions: R5 R4B R4 R3 R2 Content Detailed Descriptions Operations 1.10.5 Resource - Detailed Descriptions Detailed Descriptions for the elements in the Base Resource Definitions. Resource Definition Base Resource for everything. Control 1..1 Resource.id Definition The logical id of the resource, as used in the url for the resoure. Once assigned, this value never changes. Control 0..1 Type id 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. Control 0..1 Type Meta 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. Control 0..1 Type uri Is Modifier true 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. Control 0..1 Binding Language: Required : IETF language tag (A human language) Type code 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. Control 1..1 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. Control 0..1 Type id 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. Control 0..1 Type instant 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 StructureDefinition s that this resource claims to conform to. The URL is a reference to StructureDefinition.url . Control 0..* Type uri 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. Control 0..* Type Coding 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 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. Control 0..* Type Coding 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. © HL7.org 2011+. FHIR DSTU (v0.4.0-4902) generated on Fri, Mar 27, 2015 00:17+1100.
