Gazelle team has written a scientific paper published in the 15th International HL7 Interoperability Conference (IHIC 2015) in February 10, 2015, untitled "Model-based Analysis of HL7 CDA R2 Conformance and Requirements Coverage". The paper is an application of the tool Gazelle ObjectsChecker for the evaluation of CDA documents, based on the basic requirements of this standard. This paper contains a complete description of requirements expressed in the CDA standard and not covered by the CDA schema, and a study of the impact of such requirements in the tools of validation results and the CDA provided by national projects.

The abstract of this paper is:

I will perform two presentations about IHE Gazelle ObjectsChecker (commonly known by Model-based validation) next week during IHIC, in Prague, Czech Republic (from 9 to 11 February 2015).

The first presentation will be on  Monday 9, between 15:20 – 17:00, and entitled "IHE Gazelle ObjectsChecker: Concepts, Benefits, Demonstration and Access". This presentation will be in collaboration with art-decor Expert Group.

The planing of this presentation is :

The Gazelle team has enhanced the OrderManager tool : by now, you can check your implementation of the SWF.b profile. Actually, the tool is now able to exchange OMG and OMI messages with your system under test, for the following transactions:

  • RAD-2 : Placer Order Management
  • RAD-3 : Filler Order Management
  • RAD-4 : Procedure Schedule
  • RAD-13 : Procedure Update

Note that the tool is not yet able to handle ADT messages in version HL7v2.5.1

The process flow remains the same as for the SWF profile, simply tick the "Send HL7v2.5.1 messages ?" checkbox when configuring the simulator to send messages to your system or send HL7v2.5.1 messages to the tool.

You can also read the documentation for detailed information.

We have started the migration of the Gazelle tools to a new set of servers. The URLs to access the tools remain the same but the IP addresses and the web service endpoints have changed.
If you are using :
- PatientManager
- OrderManager
- Gazelle proxy
- Gazelle TestManagement
- LCSDSimulator
- HMWSimulator
- HPDSimulator
be careful, they are now located on a new server, so double check the connection configuration if you try to contact those tools. If you had to configure your firewall to receive messages from the tools, the new IP address is

N.B. For Order Manager, we also had to update the listening ports of HL7v2 responders by adding 100 to the original port number.

We will let you know as soon as we move other tools.

If you have any questions or concerns, feel free to contact the Gazelle team.

This is the title of the scientific paper written by members from IHE-Europe, gazelle team, and published the last April in the international scientific conference HEALTHINF 2014, at Angers, France.

The aim of this article is to communicate and to share the experience of the team, about the validation of XML documents according to healthcare standards, like CDA, HL7 V3, XDW or XDS metadatas (and any kind of XML documents based on a medical standard).

Abstract of the paper:
