This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR CompositionEuCore profile used by this Implementation Guide.
| EHDSDocument (Logical Model) | Relationship | CompositionEuCore | ||
|---|---|---|---|---|
| Element | Relation | Resource | Element | Notes |
| header | related-to | Composition | . | Dataset-level information across the Composition instance. |
| header.subject | equivalent | Composition | subject | |
| header.identifier | equivalent | Composition | identifier | Multiple identifiers allowed; Composition R4 allows 0..1, R5 0..*. setId in HL7 CDA |
| header.identifier | equivalent | Bundle | identifier | Identifier of a specific version of this document. id in HL7 CDA |
| header.author[x] | equivalent | Composition | author | |
| header.date | equivalent | Composition | date | |
| header.status | equivalent | Composition | status | |
| header.language | equivalent | Composition | language | |
| header.documentType | equivalent | Composition | type | |
| header.documentTitle | equivalent | Composition | title | |
| header.period | related-to | Composition | event.period | Map to the primary Composition.event entry. |
| header.version | related-to | Composition | extension:version〔R4〕 version〔R5〕 |
|
| header.attestation | related-to | Composition | attester | Use mode to distinguish assertions. |
| header.attestation.attester[x] | equivalent | Composition | attester.party | |
| header.attestation.datetime | equivalent | Composition | attester.time | Set attester.mode as appropriate (e.g., professional). |
| header.legalAuthentication | related-to | Composition | attester | Use attester.mode = "legal" for the legal authenticator. |
| header.legalAuthentication.legalAuthenticator[x] | related-to | Composition | attester.party | Use attester.mode = "legal" for the legal authenticator. |
| header.legalAuthentication.datetime | equivalent | Composition | attester.time | Use attester.mode = "legal" for the legal authenticator. |
| header.eventType | related-to | Composition | category | The mapping proposed reflects a possible interpretation of this element as classification of the document; DocumentReference.category should be used if used for filtering document searches. If instead it represents the type of event that occurred, event.code for 〔R4〕 and event.detail.concept for〔R5〕 |
| header.serviceSpecialty | source-is-narrower-than-target | Composition | category | The mapping proposed reflects a possible classification of the document based on the service specialty. However it is more appropriated to be captured in the DiagnosticReport.category, or in the DocumentReference.category if used for filtering document searches. |
| header.custodian | equivalent | Composition | custodian | Reference to Organization. |
| presentedForm | no-map | Composition | ||
