This module provides an XBS.b interface into OpenMRS. It is expected to receive any type of document payloads over the XDS.b interface and pass those on to the content handler with the content type of the payload.

XDS.b Behaviour

The module will enable OpenMRS to perform as Document Registry and Document Repository actors in the following transactions:

• ITI-18 Registry Stored Query
• ITI-41 Provide and Register Document Set.b
• ITI-42 Register Document Set.b
• ITI-43 Retrieve Document Set.b.

...

The SHR (with the IOL) plays a dual role of both Document Registry and Document Repository. As a registry the SHR can store metadata about documents, while as a repository, the SHR can provide the storage for these documents. The SHR must switch between roles depending on the transaction, and should, if required, be able to perform just the role of registry (or repository) for an external 3rd party repository (or registry).

Transactions

See this page: http://wiki.ihe.net/index.php?title=Cross_Enterprise_Document_Sharing as well as the technical framework documentation at http://www.ihe.net/Technical_Frameworks/#IT for technical details about the XDS.b transactions.

ITI-18 Registry Stored Query

The SHR can act as a Document Registry for Registry Stored Query requests.

ITI-41 Provide and Register Document Set.b

The SHR can act as a Document Repository for Provide and Register Document Set.b transactions. The transaction must be sent to the IOL; which will act as a Patient Feed Consumer for resolving the patient id as well as act as a Document Repository for sending an ITI-42 Register Document Set.b transaction. The SHR will act as a Document Registry for receiving the Register Document Set.b transaction, but if required, another external registry can be used. In this case the SHR will not act as Registry for the particular Provide and Register Document Set.b transaction. After patient id enrichment and sending the Register Document Set.b transaction, the IOL will forward the Provide and Register Document Set.b transaction to the SHR (acting as Document Repository) for handling.

ITI-42 Register Document Set.b

As described, the SHR can act as a Document Registry for receiving Register Document Set.b transactions. This transaction will allow Document Repositories to store metadata about the documents that they need to store.

ITI-43 Retrieve Document Set.b

The SHR can act as a Document Repository for receiving Retrieve Document Set.b requests. The transaction allows Document Consumers to retrieve specific documents from the repository.

ATNA

The Interoperability Layer will handle the sending of all ATNA audit messages (Audit Trail), as well as provide secure interfaces for communication with external systems (Node Authentication).
