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:

During the last weeks, Gazelle testbed has been enriched with new validation services. From the EVSClient, you can now access

  • A model-based validation service for audit messages (most of the audit messages defined in the context of XD*, DSUB, PDQ and PIX profiles are available)
  • A validation service of WADO queries
  • A model-based validation service for assertions produced in the context of the XUA integration profile
  • Update of the model-based validation of XD* metadatas to the latest CPs

All those services are exposed by Gazelle applications as SOAP web services; so you can also directly call them.

Also note that those validation services might be used during the Vienna connectathon to verify the conformance of the messages and documents produced by your systems; so you may want to try them out !

This year European connectathon will be held in Vienna, Austria from April, 7th to April, 11th. Participant registration period is now ended (although we are still accepting late registration) and it's now time to recruit our monitors for this coming event.

We would kindly ask those of you who want to participate to apply through our monitor recruitment form available at by February, 20th. Only applications received through this form will be taken into account when we will make our choice, based upon the profiles tested at the connectathon (we know that some of you have already filled out the form in the past, but we need this new submission). Unfortunately, we will probably not be able to accept all the applications.

The complete list of successful applications will be published by February, 28th, so that you can book your trip to Vienna.

Dear LAW implementers, 

Gazelle team has just released Gazelle HL7 Validator 2.2.1 which includes the fixes of HL7 message profiles used for the validation of messages exchanged in the context of the LAW profile. The constraints are based on the revision 1.3 of the LAW supplement. 

From now on, you can test your messages with the new profiles, either directly through the web service or from the user-friendly interface, EVS Client.

We did our best to fit the requirements but error is human and we may have missed some contraints or wrongly understand some others.

Do not hesistate to report any issue in our bug tracker at if you meet errors or inconsistencies.

Please, also note that the Order Manager tool has not been updated yet; so the validation tool may report issues on the messages generated by the tool.

Dear all,

Gazelle testbed has been enriched with a new validation service dedicated to the messages exchanged in the context of the XCPD profile. By now, not all the messages are available for testing but you can already try out

  • [ITI-56] Patient Location Query Request
  • [ITI-56] Patient Location Query Response
  • [ITI-55] Cross-Gateway Patient Discovery Request
  • [ITI-55] Cross-Gateway Patiet Discovery Request (Deferred response option)

You can access this new validation service from the EVS Client application 

Do not hesitate to report issues in our bug issue tracker at
