Group 1 Mapping from http://hl7.org/fhir/StructureDefinition/Bundle|5.0.0 to Bundleversion: 4.3.0)

Source CodeRelationshipTarget CodeComment
Bundle.meta (meta)is equivalent toBundle.metaElement `Bundle.meta` is mapped to FHIR R4B element `Bundle.meta` as `Equivalent`.
Bundle.implicitRules (implicitRules)is equivalent toBundle.implicitRulesElement `Bundle.implicitRules` is mapped to FHIR R4B element `Bundle.implicitRules` as `Equivalent`. 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. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of its narrative along with other profiles, value sets, etc.
Bundle.language (language)is equivalent toBundle.languageElement `Bundle.language` is mapped to FHIR R4B element `Bundle.language` as `Equivalent`. 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).
Bundle.identifier (identifier)is equivalent toBundle.identifierElement `Bundle.identifier` is mapped to FHIR R4B element `Bundle.identifier` as `Equivalent`. Persistent identity generally only matters for batches of type Document, Message, and Collection. It would not normally be populated for search and history results and servers ignore Bundle.identifier when processing batches and transactions. For Documents the .identifier SHALL be populated such that the .identifier is globally unique.
Bundle.type (type)maps to wider conceptBundle.typeElement `Bundle.type` is mapped to FHIR R4B element `Bundle.type` as `SourceIsBroaderThanTarget`. It's possible to use a bundle for other purposes (e.g. a document can be accepted as a transaction). This is primarily defined so that there can be specific rules for some of the bundle types.
Bundle.timestamp (timestamp)is equivalent toBundle.timestampElement `Bundle.timestamp` is mapped to FHIR R4B element `Bundle.timestamp` as `Equivalent`. For many bundles, the timestamp is equal to .meta.lastUpdated, because they are not stored (e.g. search results). When a bundle is placed in a persistent store, .meta.lastUpdated will be usually be changed by the server. When the bundle is a message, a middleware agent altering the message (even if not stored) SHOULD update .meta.lastUpdated. .timestamp is used to track the original time of the Bundle, and SHOULD be populated. Usage: * document : the date the document was created. Note: the composition may predate the document, or be associated with multiple documents. The date of the composition - the authoring time - may be earlier than the document assembly time * message : the date that the content of the message was assembled. This date is not changed by middleware engines unless they add additional data that changes the meaning of the time of the message * history : the date that the history was assembled. This time would be used as the _since time to ask for subsequent updates * searchset : the time that the search set was assembled. Note that different pages MAY have different timestamps but need not. Having different timestamps does not imply that subsequent pages will represent or include changes made since the initial query * transaction | transaction-response | batch | batch-response | collection : no particular assigned meaning The timestamp value should be greater than the lastUpdated and other timestamps in the resources in the bundle, and it should be equal or earlier than the .meta.lastUpdated on the Bundle itself.
Bundle.total (total)is equivalent toBundle.totalElement `Bundle.total` is mapped to FHIR R4B element `Bundle.total` as `Equivalent`. Only used if the bundle is a search result set. The total does not include resources such as OperationOutcome and included resources, only the total number of matching resources.
Bundle.link (link)maps to wider conceptBundle.linkElement `Bundle.link` is mapped to FHIR R4B element `Bundle.link` as `Equivalent`. Both Bundle.link and Bundle.entry.link are defined to support providing additional context when Bundles are used (e.g. [HATEOAS](http://en.wikipedia.org/wiki/HATEOAS)). Bundle.entry.link corresponds to links found in the HTTP header if the resource in the entry was [read](https://hl7.org/fhir/http..html#read) directly. This specification defines some specific uses of Bundle.link for [searching](https://hl7.org/fhir/search.html#.html#conformance) and [paging](https://hl7.org/fhir/http.ht.html#paging), but no specific uses for Bundle.entry.link, and no defined function in a transaction - the meaning is implementation specific. The behavior of navigation link types (next/prev/first/last) are well defined for searchset and history Bundles but are not currently defined for other types. Implementers who choose to use such link relationships for other bundle types will need to negotiate behavior with their interoperability partners.
Bundle.link.relation (relation)maps to wider conceptBundle.link.relationElement `Bundle.link.relation` is mapped to FHIR R4B element `Bundle.link.relation` as `Equivalent`.
Bundle.link.url (url)is equivalent toBundle.link.urlElement `Bundle.link.url` is mapped to FHIR R4B element `Bundle.link.url` as `Equivalent`.
Bundle.entry (entry)maps to wider conceptBundle.entryElement `Bundle.entry` is mapped to FHIR R4B element `Bundle.entry` as `Equivalent`.
Bundle.entry.link (link)is equivalent toBundle.entry.linkElement `Bundle.entry.link` is mapped to FHIR R4B element `Bundle.entry.link` as `Equivalent`.
Bundle.entry.fullUrl (fullUrl)is equivalent toBundle.entry.fullUrlElement `Bundle.entry.fullUrl` is mapped to FHIR R4B element `Bundle.entry.fullUrl` as `Equivalent`. fullUrl might not be [unique in the context of a resource](https://hl7.org/fhir/bundle.html#bu.html#bundle-unique). Note that since [FHIR resources do not need to be served through the FHIR API](https://hl7.org/fhir/references.html), the fullURL might be a URN or an absolute URL that does not end with the logical id of the resource (Resource.id). However, but if the fullUrl does look like a RESTful server URL (e.g. meets the [regex](https://hl7.org/fhir/refere.html#regex), then the 'id' portion of the fullUrl SHALL end with the Resource.id. Note that the fullUrl is not the same as the canonical URL - it's an absolute url for an endpoint serving the resource (these will happen to have the same value on the canonical server for the resource with the canonical URL).
Bundle.entry.resource (resource)is equivalent toBundle.entry.resourceElement `Bundle.entry.resource` is mapped to FHIR R4B element `Bundle.entry.resource` as `Equivalent`.
Bundle.entry.search (search)maps to wider conceptBundle.entry.searchElement `Bundle.entry.search` is mapped to FHIR R4B element `Bundle.entry.search` as `Equivalent`.
Bundle.entry.search.mode (mode)is equivalent toBundle.entry.search.modeElement `Bundle.entry.search.mode` is mapped to FHIR R4B element `Bundle.entry.search.mode` as `Equivalent`. There is only one mode. In some corner cases, a resource may be included because it is both a match and an include. In these circumstances, 'match' takes precedence.
Bundle.entry.search.score (score)is equivalent toBundle.entry.search.scoreElement `Bundle.entry.search.score` is mapped to FHIR R4B element `Bundle.entry.search.score` as `Equivalent`. Servers are not required to return a ranking score. 1 is most relevant, and 0 is least relevant. Often, search results are sorted by score, but the client may specify a different sort order. See [Patient Match](https://hl7.org/fhir/patient-operation-match.html) for the EMPI search which relates to this element.
Bundle.entry.request (request)maps to wider conceptBundle.entry.requestElement `Bundle.entry.request` is mapped to FHIR R4B element `Bundle.entry.request` as `Equivalent`.
Bundle.entry.request.method (method)is equivalent toBundle.entry.request.methodElement `Bundle.entry.request.method` is mapped to FHIR R4B element `Bundle.entry.request.method` as `Equivalent`.
Bundle.entry.request.url (url)is equivalent toBundle.entry.request.urlElement `Bundle.entry.request.url` is mapped to FHIR R4B element `Bundle.entry.request.url` as `Equivalent`. E.g. for a Patient Create, the method would be "POST" and the URL would be "Patient". For a Patient Update, the method would be PUT and the URL would be "Patient/[id]".
Bundle.entry.request.ifNoneMatch (ifNoneMatch)is equivalent toBundle.entry.request.ifNoneMatchElement `Bundle.entry.request.ifNoneMatch` is mapped to FHIR R4B element `Bundle.entry.request.ifNoneMatch` as `Equivalent`.
Bundle.entry.request.ifModifiedSince (ifModifiedSince)is equivalent toBundle.entry.request.ifModifiedSinceElement `Bundle.entry.request.ifModifiedSince` is mapped to FHIR R4B element `Bundle.entry.request.ifModifiedSince` as `Equivalent`.
Bundle.entry.request.ifMatch (ifMatch)is equivalent toBundle.entry.request.ifMatchElement `Bundle.entry.request.ifMatch` is mapped to FHIR R4B element `Bundle.entry.request.ifMatch` as `Equivalent`.
Bundle.entry.request.ifNoneExist (ifNoneExist)is equivalent toBundle.entry.request.ifNoneExistElement `Bundle.entry.request.ifNoneExist` is mapped to FHIR R4B element `Bundle.entry.request.ifNoneExist` as `Equivalent`.
Bundle.entry.response (response)maps to wider conceptBundle.entry.responseElement `Bundle.entry.response` is mapped to FHIR R4B element `Bundle.entry.response` as `Equivalent`.
Bundle.entry.response.status (status)is equivalent toBundle.entry.response.statusElement `Bundle.entry.response.status` is mapped to FHIR R4B element `Bundle.entry.response.status` as `Equivalent`.
Bundle.entry.response.location (location)is equivalent toBundle.entry.response.locationElement `Bundle.entry.response.location` is mapped to FHIR R4B element `Bundle.entry.response.location` as `Equivalent`.
Bundle.entry.response.etag (etag)is equivalent toBundle.entry.response.etagElement `Bundle.entry.response.etag` is mapped to FHIR R4B element `Bundle.entry.response.etag` as `Equivalent`. Etags match the Resource.meta.versionId. The ETag has to match the version id in the header if a resource is included.
Bundle.entry.response.lastModified (lastModified)is equivalent toBundle.entry.response.lastModifiedElement `Bundle.entry.response.lastModified` is mapped to FHIR R4B element `Bundle.entry.response.lastModified` as `Equivalent`. This has to match the same time in the meta header (meta.lastUpdated) if a resource is included.
Bundle.entry.response.outcome (outcome)is equivalent toBundle.entry.response.outcomeElement `Bundle.entry.response.outcome` is mapped to FHIR R4B element `Bundle.entry.response.outcome` as `Equivalent`. For a POST/PUT operation, this is the equivalent outcome that would be returned for prefer = operationoutcome - except that the resource is always returned whether or not the outcome is returned. This outcome is not used for error responses in batch/transaction, only for hints and warnings. In a batch operation, the error will be in Bundle.entry.response, and for transaction, there will be a single OperationOutcome instead of a bundle in the case of an error.
Bundle.signature (signature)is equivalent toBundle.signatureElement `Bundle.signature` is mapped to FHIR R4B element `Bundle.signature` as `Equivalent`. The signature could be created by the "author" of the bundle or by the originating device. Requirements around inclusion of a signature, verification of signatures and treatment of signed/non-signed bundles is implementation-environment specific.

Group 2 Mapping from http://hl7.org/fhir/StructureDefinition/Bundle|5.0.0 to R5: document | message | transaction | transaction-response | batch | batch-response | history | searchset | collection | subscription-notificationversion: 0.1.0)

Bundle.type (type)is equivalent toExtension (R5: document | message | transaction | transaction-response | batch | batch-response | history | searchset | collection | subscription-notification)Element `Bundle.type` is mapped to FHIR R4B element `Bundle.type` as `SourceIsBroaderThanTarget`. It's possible to use a bundle for other purposes (e.g. a document can be accepted as a transaction). This is primarily defined so that there can be specific rules for some of the bundle types.

Group 4 Mapping from http://hl7.org/fhir/StructureDefinition/Bundle|5.0.0 to R5: Issues with the Bundle (new)version: 0.1.0)

Source CodeRelationshipTarget CodeComment
Bundle.issues (issues)maps to wider conceptExtension (R5: Issues with the Bundle (new))Element `Bundle.issues` has a context of Bundle based on following the parent source element upwards and mapping to `Bundle`. Element `Bundle.issues` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element). Usage notes: These issues and warnings must apply to the Bundle as a whole, not to individual entries.Messages relating to the processing of individual entries (e.g. in a batch or transaction) SHALL be reported in the entry.response.outcome for that entry. If there are errors that arise in the creation of the Bundle, then that should be handled by an OperationOutcome being returned instead of the Bundle.
