Releases

ANSI/HL7 V3 TR ebXML, R1-2008; (DSTU) - Transport Specification - ebXML, R1 HL7 V3: Transport Specification - ebXML, Release 2

Summary

The HL7 Message Transport Specifications documents provide details as to the usage of a variety of communication transports for the exchange of HL7 based content, messages and documents. Currently specification documents for MLLP, SOAP-Web Services and ebXML are included in the package for separate review or separate balloting. Specification documents for other transports may be included as they are available.

Description

These Transport Specifications are not to be confused with the content of Transmission Infrastructure. Transmission infrastructure describes the information model, messages and interactions related to the assembly of an HL7 v3 composite message. The Transport Specifications address moving the message payload (the HL7 v3 composite message and/or HL7 v2 composite message) from sender to receiver. These transports are all capable of moving HL7 v3 composite messages and may also support moving HL7 v2 and CDA composite messages.

Business Case (Intended Use, Customers)

The purpose of the ebXML message wrapper is to provide a secure, flexible transport for exchanging HL7 messages and other content, and potentially other message formats, between message handling interfaces or ebXML Message Service Handlers (ebXML MSH).

Benefits

The ebXML Transport supports reliable messaging, encryption, authenticaltion and digital signatures, and exchange of messages over a variety of lower level transports such as HTTP, SMTP and TCP/IP.

Transport Specification - MLLP, Release 2 ( Normative )

Summary

The HL7 Message Transport Specifications documents provide details as to the usage of a variety of communication transports for the exchange of HL7 based content, messages and documents. Currently specification documents for MLLP, SOAP-Web Services and ebXML are included in the package for separate review or separate balloting. Specification documents for other transports may be included as they are available.

Description

These Transport Specifications are not to be confused with the content of Transmission Infrastructure. Transmission infrastructure describes the information model, messages and interactions related to the assembly of an HL7 v3 composite message. The Transport Specifications address moving the message payload (the HL7 v3 composite message and/or HL7 v2 composite message) from sender to receiver. These transports are all capable of moving HL7 v3 composite messages and may also support moving HL7 v2 and CDA composite messages.

This standard specifies Release 2 of the Minimal Lower Layer Message Transport protocol (MLLP, a.k.a. MLP). Release 1 of the MLLP Message Transport protocol (a version without built-in Reliable delivery assurances) has a long history of use within the HL7 community.

In this release the MLLP Message Transport protocol has been extended by commit acknowledgements. This is done in order to create a reliable Message Transport protocol, a requirement for all Message Transport protocols used to transport HL7 Version 3 content. See the new Abstract Transport Specification document for this and other transport protocol requirements.

Business Case (Intended Use, Customers)

The purpose of the MLLP Protocol (Minimum Lower Layer Protocol) is to provide both a minimalistic OSI-session layer framing protocol as well as a minimalistic reliable transport protocol. If security is an issue, additional protocols or technologies will have to be layered on top of MLLP to achieve these goals.

Transport Specification: ISO 9660 Removable Media Release 1

Summary

This document specifies the transfer of HL7 messages or documents via ISO 9660 removable storage media. Examples of ISO 9660 removable media include common format CDs and USB flash memory cards. The media format must support the various use-cases listed in this document.

Business Case (Intended Use, Customers)

This transport is required when messages or documents are to be transmitted between offline applications. Please note that this document only specifies how messages and documents should be transmitted, it doesn't specify how messages or documents should be stored or archived.

Transport Specification - Web Services Profile , Release 1 DSTU

Summary

The purpose of the Web Services Profile (WSP) is to provide implementation guidelines to promote interoperability between implementers that want to exchange HL7 Version 3 messages using standards that fall under the general definition of Web Services. With the objective of leveraging the effort of the industry to promote interoperability, recommendations from organizations like WS-I, W3C and other will be taken into account.
