Source CodeRelationshipTarget CodeComment
Substance.meta (meta)maps to wider conceptSubstance.metaElement `Substance.meta` is mapped to FHIR R4 element `Substance.meta` as `SourceIsBroaderThanTarget`. The mappings for `Substance.meta` do not cover the following types: Meta. The mappings for `Substance.meta` do not cover the following types based on type expansion: lastUpdated, profile, security, tag, versionId.
Substance.implicitRules (implicitRules)is equivalent toSubstance.implicitRulesElement `Substance.implicitRules` is mapped to FHIR R4 element `Substance.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 as much as possible.
Substance.language (language)is equivalent toSubstance.languageElement `Substance.language` is mapped to FHIR R4 element `Substance.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).
Substance.text (text)maps to wider conceptSubstance.textElement `Substance.text` is mapped to FHIR R4 element `Substance.text` as `SourceIsBroaderThanTarget`. The mappings for `Substance.text` do not cover the following types: Narrative. The mappings for `Substance.text` do not cover the following types based on type expansion: div, status. Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative.
Substance.contained (contained)is equivalent toSubstance.containedElement `Substance.contained` is mapped to FHIR R4 element `Substance.contained` as `SourceIsBroaderThanTarget`. 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.
Substance.identifier (identifier)maps to wider conceptSubstance.identifierElement `Substance.identifier` is mapped to FHIR R4 element `Substance.identifier` as `SourceIsBroaderThanTarget`. The mappings for `Substance.identifier` do not cover the following types: Identifier. The mappings for `Substance.identifier` do not cover the following types based on type expansion: assigner, period, system, type, use, value. This identifier is associated with the kind of substance in contrast to the Substance.instance.identifier which is associated with the package/container.
Substance.category (category)is equivalent toSubstance.categoryElement `Substance.category` is mapped to FHIR R4 element `Substance.category` as `Equivalent`. The level of granularity is defined by the category concepts in the value set. More fine-grained filtering can be performed using the metadata and/or terminology hierarchy in Substance.code.
Substance.code (code)is equivalent toSubstance.codeElement `Substance.code` is mapped to FHIR R4 element `Substance.code` as `Equivalent`. This could be a reference to an externally defined code. It could also be a locally assigned code (e.g. a formulary), optionally with translations to the standard drug codes.
Substance.description (description)is equivalent toSubstance.descriptionElement `Substance.description` is mapped to FHIR R4 element `Substance.description` as `Equivalent`.
Substance.instance (instance)maps to wider conceptSubstance.instanceElement `Substance.instance` is mapped to FHIR R4 element `Substance.instance` as `Equivalent`.
Substance.instance.identifier (identifier)maps to wider conceptSubstance.instance.identifierElement `Substance.instance.identifier` is mapped to FHIR R4 element `Substance.instance.identifier` as `SourceIsBroaderThanTarget`. The mappings for `Substance.instance.identifier` do not cover the following types: Identifier.

Substance.instance.expiry (expiry)is equivalent toSubstance.instance.expiryElement `Substance.instance.expiry` is mapped to FHIR R4 element `Substance.instance.expiry` as `Equivalent`.
Substance.instance.quantity (quantity)is equivalent toSubstance.instance.quantityElement `Substance.instance.quantity` is mapped to FHIR R4 element `Substance.instance.quantity` as `Equivalent`.
Substance.ingredient (ingredient)maps to wider conceptSubstance.ingredientElement `Substance.ingredient` is mapped to FHIR R4 element `Substance.ingredient` as `Equivalent`.
Substance.ingredient.quantity (quantity)maps to wider conceptSubstance.ingredient.quantityElement `Substance.ingredient.quantity` is mapped to FHIR R4 element `Substance.ingredient.quantity` as `SourceIsBroaderThanTarget`. The mappings for `Substance.ingredient.quantity` do not cover the following types: Ratio. The mappings for `Substance.ingredient.quantity` do not cover the following types based on type expansion: denominator, numerator.
Substance.ingredient.substance (substance)maps to wider conceptSubstance.ingredient.substance[x]Element `Substance.ingredient.substance` is mapped to FHIR R4 element `Substance.ingredient.substance[x]` as `SourceIsBroaderThanTarget`. The mappings for `Substance.ingredient.substance` do not cover the following types based on type expansion: display, reference. The standard extension `alternate-reference` has been mapped as the representation of FHIR DSTU2 element `Substance.ingredient.substance` with unmapped reference targets: Substance. Source element `Substance.ingredient.substance` has unmapped reference types. While the target element `Substance.ingredient.substance[x]` is a choice type and does not allow extensions, the `alternate-reference` extension can be applied to Reference values within it.
