7.8 7.9 Resource StructureMap - Content

FHIR Infrastructure icon Work Group Maturity Level : 2 4   Trial Use Security Category : Anonymous Compartments : Not linked to any No defined compartments

A Map of relationships between 2 structures that can be used to transform data.

The StructureMap resource defines a detailed set of rules that describe how one Structure is related to another and provides sufficient detail to allow for automated conversion of instances.

The intention of the structure map resource is to allow a specialist in formats and interoperability to specify the full relationships between two structures (e.g. a CDA document and a set of FHIR resources), and then many different systems - both testing and production clinical systems - can leverage that to automatically transform from one format to the other.

Maps are unidirectional: they map from the source structure to the target structure, and no reverse map is implied. Even if the mapping is simple, and loss-less, it cannot be assumed that there are no conditions that might additionally apply in the reverse direction.

The mapping language, along with a concrete syntax, is defined in detail in the FHIR Mapping Language . The StructureMap resource represents the abstract syntax, and the concrete syntax is the recommended narrative representation for a StructureMap. See also the Tutorial .

Note that many mappings between models only establish conceptual equivalence between the structures. These models are useful because they quickly convey how the structures are related to humans, whereas more maps with sufficient detail to support instance transformation are necessarily full of fine detail that can obscure the conceptual relationships. The ConceptMap resource is suitable for representing high level relationships between models, while this StructureMap resource is intended to describe the full details that need to be known in order to transform an instance of data from one structure to another.

The StructureMap resource assumes that both the source and the target models are fully defined using StructureDefinition resources - either resources, or logical models, and is described accordingly. However, there is no direct relationship between the mapping language contained in the StructureMap resource, and the existence of the appropriate structure definitions, so that this mapping language could be used to define a map from an HL7 v2 V2 message to a CDA document. Note, that various implementation contexts may introduce a direct relationship (e.g. see [op to defined]).

It's possible to apply the mapping language to structures that do not even have (or cannot have) formally defined types, although the type-related parts of the mapping language cannot be used in these cases.

The Mapping Language and the StructureMap resource are built on top of FHIRPath , and a FHIRPath implementation is required in order to execute a StructureMap.

Each structure map contains, in addition to the standard metadata that all conformance resources contain, the following information:

  • A list of the structure definitions referenced by the map
  • A list of other structure maps that the map uses
  • One or more groups of rules that describe how content in the source is transformed to content in the target

Each group of rules defines a set of input and output variables that must be passed when the group is invoked in a particular context. When a group is invoked, all the rules in the group are checked to see whether they apply.

Each rule may have some or all of the following properties:

  • A name - used as the identity in internal references, and traces
  • Contexts in both source and target models that define where the rule applies
  • A set of source elements that provide data to be mapped
  • Conditions that specify if the rule is to apply
  • A set of target elements that will be created
  • Transform rules that describe how raw data is converted from the source format to the target format (e.g. string manipulation)
  • Flags for how instances that can repeat are handled
  • Additional rules that apply to the newly created elements (e.g. new contexts)

The mapping language is entirely declarative; there is no imperative or procedural aspects to the definitions.

StructureMap ( DomainResource ) + CanonicalResource An absolute URI that is used to identify this structure map when it is referenced in a specification, model, design or an instance; also called its canonical identifier. This SHOULD be globally unique and SHOULD be a literal address at which at which an authoritative instance of this structure map is (or will be) published. This URL can be the target of a canonical reference. It SHALL remain the same when the structure map is stored on different servers url : uri [1..1] A formal identifier that is used to identify this structure map when it is represented in other formats, or referenced in a specification, model, design or an instance identifier : Identifier [0..*] The identifier that is used to identify this version of the structure map when it is referenced in a specification, model, design or instance. This is an arbitrary value managed by the structure map author and is not expected to be globally unique. For example, it might be a timestamp (e.g. yyyymmdd) if a managed version is not available. There is also no expectation that versions can be placed in a lexicographical sequence version : string [0..1] Indicates the mechanism used to compare versions to determine which is more current versionAlgorithm[x] : DataType [0..1] « string | Coding ; null (Strength=Extensible) VersionAlgorithm + » A natural language name identifying the structure map. This name should be usable as an identifier for the module by machine processing applications such as code generation name : string [1..1] « This element has or is affected by some invariants C » A short, descriptive, user-friendly title for the structure map title : string [0..1] The status of this structure map. Enables tracking the life-cycle of the content (this element modifies the meaning of other elements) status : code [1..1] « null (Strength=Required) PublicationStatus ! » A Boolean value to indicate that this structure map is authored for testing purposes (or education/evaluation/marketing) and is not intended to be used for genuine usage experimental : boolean [0..1] The date (and optionally time) when the structure map was published. last significantly changed. The date must change when the business version changes and it must change if the status code changes.

Path Definition ValueSet Type Reference Documentation
StructureMap.versionAlgorithm[x] VersionAlgorithm Required Extensible PublicationStatus

Indicates the mechanism used to compare versions to determine which is more current.

StructureMap.status PublicationStatus Extensible Required Jurisdiction ValueSet

The lifecycle status of an artifact.

StructureMap.jurisdiction JurisdictionValueSet Required Extensible StructureMapModelMode

This value set defines a base set of codes for country, country subdivision and region for indicating where a resource is intended to be used.

Note: The codes for countries and country subdivisions are taken from ISO 3166 icon while the codes for "supra-national" regions are from UN Standard country or area codes for statistical use (M49) icon.

StructureMap.structure.mode StructureMapModelMode Required StructureMapGroupTypeMode

How the referenced structure is used in this mapping.

StructureMap.group.typeMode StructureMapGroupTypeMode Required StructureMapInputMode

If this is the default rule set to apply for the source type, or this combination of types.

StructureMap.group.input.mode StructureMapInputMode Required StructureMapSourceListMode

Mode for this instance of data.

StructureMap.group.rule.source.listMode StructureMapSourceListMode Required StructureMapContextType

If field is a list, how to manage the source.

StructureMap.group.rule.target.listMode StructureMapTargetListMode Required StructureMapTargetListMode

If field is a list, how to manage the production.

StructureMap.group.rule.target.transform StructureMapTransform Required StructureMapTransform

How data is copied/created.
