EFA XDR/XDS Binding

Bitte markieren Sie Kommentare zu diesem Abschnitt mit dem Code {EDXDg.01}

This section specifies the binding of the EFA components to IHE-ITI actors and the binding of the EFA operations to IHE-ITI transactions.

The EFA actors MUST be bound to IHE-ITI actors as follows:

EFA actor	IHE-ITI actors	Operations
EFA Client	Document Source	out-bound: createECR, closeECR, registerConsent, createPartition, provideData
	Document Consumer	out-bound: listPartitions, listPartitionContents, retrieveData
EFA Resource Manager	Document Repository	in-bound: createECR, closeECR, registerConsent
	Document Source	out-bound: registerRecordLocation
	Document Recipient	in-bound: registerRecordLocation
	Initiating Gateway with XDS Affinity Domain Option (see IHE-ITI-TF-Vol1#18.2.1)	out-bound: listRecordLocations
	Responding Gateway grouped with Document Consumer (see IHE-ITI-TF-Vol1#18.2.3.2)	in-bound: listRecordLocations
EFA Document Registry	Document Registry	in-bound: listPartitions, listPartitionContent, registerData
	Initiating Gateway with XDS Affinity Domain Option (see IHE-ITI-TF-Vol1#18.2.1)	in-bound: listPartitions, listPartitionContent out-bound: listPartitions, listPartitionContent
	Responding Gateway grouped with Document Consumer (see IHE-ITI-TF-Vol1#18.2.3.2)	in-bound: listPartitions, listPartitionContent out-bound: listPartitions, listPartitionContent
EFA Document Repository	Document Repository	in-bound: createPartition, provideData, retrieveData out-bound: registerData
	Initiating Gateway with XDS Affinity Domain Option (see IHE-ITI-TF-Vol1#18.2.1)	in-bound: retrieveData out-bound: retrieveData
	Responding Gateway grouped with Document Consumer (see IHE-ITI-TF-Vol1#18.2.3.2)	in-bound: listPartitions, listPartitionContent out-bound: listPartitions, listPartitionContent

The EFA operations MUST be bound to IHE-ITI transactions as follows:

EFA Service Functional Model	IHE-ITI Profile	Binding
createECR	Provide and Register Document Set ITI-41	createECR
createPartition	Provide and Register Document Set ITI-41	createPartition
closeECR	Provide and Register Document Set ITI-41	closeECR
listPartitions	Registry Stored Query ITI-18	listPartitions
registerConsent	Provide and Register Document Set ITI-41	registerConsent
listRecordLocations	Cross Gateway Query ITI-38	listRecordLocations
registerRecordLocation	Provide and Register Document Set-b ITI-41	registerRecordLocation
registerData	Register Document Set ITI-42	registerData
listPartitionContent	Registry Stored Query ITI-18	listPartitionContent
provideData	Provide and Register Document Set ITI-41	provideData
retrieveData	Retrieve Document Set ITI-43	retrieveData

Constraints and Triggers

All bindings to the ITI-41 transaction MUST satisfy a set of common constraints and a distinct set of constraints which triggers a certain binding.

The common constraints are:

• The SubmissionSet MUST NOT have EFA semantics.
• The HasMember(4)-Associations (SubmissionSet to XDSDocumentEntry) MUST have the SubmissionSetStatus-attribute set to "Original".
• The HasMember-Associations MUST reference exactly one XDSFolder.
• The XDSFolder MUST satisfy the EFA XDS Folder Metadata Binding.
• All XDSDocument-Elements MUST be associated with the XDSFolder.
• All XDSDocument-Elements MUST satisfy the EFA XDS Document Metadata Binding.

The distinct sets of constraints are defined in the table below (R = required, O = optional, - = forbidden).

Constraints	Triggers for bindings
	createECR	closeECR	registerConsent	createPartition	provideData
One XDSDocument is a consentInfo which gives a new consent or does not revoke all active consents	R	-	R	-	-
One XDSDocument is a consentInfo, which revokes all active consents	-	R	-	-	-
An XDSFolder is provided (uniqueID)	R	O	O	R	-
An XDSFolder is referenced (uniqueID)	-	O	O	-	R
