Mapping from http://hl7.org/fhir/4.0 to http://hl7.org/fhir/4.3
Group 1 Mapping from http://hl7.org/fhir/StructureDefinition/Subscription|4.0.1 to Subscriptionversion: 4.3.0)
| Source Code | Relationship | Target Code | Comment |
| Subscription.meta (meta) | is equivalent to | Subscription.meta | Element `Subscription.meta` is mapped to FHIR R4B element `Subscription.meta` as `Equivalent`. |
| Subscription.implicitRules (implicitRules) | is equivalent to | Subscription.implicitRules | Element `Subscription.implicitRules` is mapped to FHIR R4B element `Subscription.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 it's narrative along with other profiles, value sets, etc. |
| Subscription.language (language) | is equivalent to | Subscription.language | Element `Subscription.language` is mapped to FHIR R4B element `Subscription.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). |
| Subscription.text (text) | is equivalent to | Subscription.text | Element `Subscription.text` is mapped to FHIR R4B element `Subscription.text` as `Equivalent`. Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later. |
| Subscription.contained (contained) | is equivalent to | Subscription.contained | Element `Subscription.contained` is mapped to FHIR R4B element `Subscription.contained` as `Equivalent`. This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels. |
| Subscription.status (status) | is equivalent to | Subscription.status | Element `Subscription.status` is mapped to FHIR R4B element `Subscription.status` as `Equivalent`. A client can only submit subscription resources in the requested or off state. Only the server can move a subscription from requested to active, and then to error. Either the server or the client can turn a subscription off. This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid. |
| Subscription.contact (contact) | is equivalent to | Subscription.contact | Element `Subscription.contact` is mapped to FHIR R4B element `Subscription.contact` as `Equivalent`. |
| Subscription.end (end) | is equivalent to | Subscription.end | Element `Subscription.end` is mapped to FHIR R4B element `Subscription.end` as `Equivalent`. The server is permitted to deviate from this time but should observe it. |
| Subscription.reason (reason) | is equivalent to | Subscription.reason | Element `Subscription.reason` is mapped to FHIR R4B element `Subscription.reason` as `Equivalent`. |
| Subscription.criteria (criteria) | is equivalent to | Subscription.criteria | Element `Subscription.criteria` is mapped to FHIR R4B element `Subscription.criteria` as `Equivalent`. The rules are search criteria (without the [base] part). Like Bundle.entry.request.url, it has no leading "/". |
| Subscription.error (error) | is equivalent to | Subscription.error | Element `Subscription.error` is mapped to FHIR R4B element `Subscription.error` as `Equivalent`. |
| Subscription.channel (channel) | maps to wider concept | Subscription.channel | Element `Subscription.channel` is mapped to FHIR R4B element `Subscription.channel` as `Equivalent`. |
| Subscription.channel.type (type) | is equivalent to | Subscription.channel.type | Element `Subscription.channel.type` is mapped to FHIR R4B element `Subscription.channel.type` as `Equivalent`. |
| Subscription.channel.endpoint (endpoint) | is equivalent to | Subscription.channel.endpoint | Element `Subscription.channel.endpoint` is mapped to FHIR R4B element `Subscription.channel.endpoint` as `Equivalent`. For rest-hook, and websocket, the end-point must be an http: or https: URL; for email, a mailto: url, for sms, a tel: url, and for message the endpoint can be in any form of url the server understands (usually, http: or mllp:). The URI is allowed to be relative; in which case, it is relative to the server end-point (since there may be more than one, clients should avoid using relative URIs). |
| Subscription.channel.payload (payload) | is equivalent to | Subscription.channel.payload | Element `Subscription.channel.payload` is mapped to FHIR R4B element `Subscription.channel.payload` as `Equivalent`. Sending the payload has obvious security implications. The server is responsible for ensuring that the content is appropriately secured. |
| Subscription.channel.header (header) | is equivalent to | Subscription.channel.header | Element `Subscription.channel.header` is mapped to FHIR R4B element `Subscription.channel.header` as `Equivalent`. Exactly what these mean depend on the channel type. They can convey additional information to the recipient and/or meet security requirements; for example, support of multiple headers in the outgoing notifications for rest-hook type subscriptions. |
