IHE XDS mapping to HL7 v3

This section contains a mapping from the IHE XDS artifacts (see the ITI Technical Framework; as well as the XDS-I specs.) to the HL7 Act Reference shared message topic.

Mapping of IHE Transactions to HL7 Domains/Interactions

At the transaction level there are multiple mappings, depending on whether one uses a Document registry (XDS, Medical Records domain) or an Object registry (Shared Messages Act Reference topic)

ITI-14: Register Document Set:

• COMT (Shared Messages) – Act Reference Activate/Revise/Nullify Registration Request interactions + Application Acks
• RCMR (Medical Records) – Document .. Notification

ITI-15: Provide and Register Document Set:

• RCMR (Medical Records) – Various “Document …” interactions

ITI-16: Query Documents:

• RCMR (Medical Records) – Find Document Metadata Query/Response
• COMT (Shared Messages) – Find Act Reference Registries Query/Response

ITI-17: Retrieve Document:

• RCMR (Medical Records) – Find Document Metadata and Content Query/Response

Terminology Mapping

• Document Entry: Act Reference (of any class, in any mood)
• Folder: Act (and Act Reference) of class FOLDER
• Submission Set: Batch Transmission wrapper. The purpose of a submission set is to guarantee atomicity of a set of submissions. A Submission Set is a persistent entity, whereas a batch wrapper in HL7 isn’t.

Metadata attribute mapping

The focus of the mapping is to check the functionality covered by the COMT Act Reference R-MIM.
