Gazelle has a feature that allows participants in a testing session to share sample objects with other participants.

In Gazelle a "sample" is any object or message that an application creates and is used by another application. Typical samples include: 

• DICOM object
• ISO image of DICOM CD-ROM or DVD
• CDA documents
• XDW documents
• HL7 messages
• ...others...

Gazelle Test Management uses the profiles and actors selected during Connectathon System Registration to determine which systems are 'creators' of samples and which system are 'consumers' of samples

Creators upload a file containing their sample into Gazelle.

Creators may use the Gazelle EVSClient tool to perform validation of the sample.

Consumers find samples uploaded by their Creator peers.  Consumers download the samples and are able to test them with their application.

The following pages in this section detail how to upload, validate and access samples in gazelle.

Creators of samples include DICOM Modalities, Content Creators of CDA documents, and other actors.  These systems upload samples into Gazelle so that they are available to their test partners.

To upload a new sample, select Gazelle menu Connectathon-->Connectathon-->List of samples

When you select your system from the dropdown list, the "Samples to share" tab shows a list of samples for which your system is a creator.  The list is based the profiles/actors in your system registration.     

To add a new sample, for click the green "+" button next to the sample type.

Give your sample a name as follows:

Next complete the "summary" tab, and on the "file(s)" tab, upload a file containing your sample.

When you have finished uploading your file and saving your sample, the sample entry in Gazelle will look like this:

After creators upload their sample file(s) into gazelle, it is possible to validate that content using the Gazelle EVSClient tool.  (Note that Gazelle has validators many sample types, but not all.)

On the "Samples to Share" tab, find the entry for the file uploaded.  Clicking on the green arrow will call the Gazelle EVSClient application:

In the EVSClient application, select the proper validator from the dropdown list.  In this example, we are validating a DICOM image:

Depending on the type of sample you are validating, you may need to choose the tool and execute the validation.  The results will appear at the bottom of the page:

And, here is a screen shot of a the validation result for a CDA document.  The gazelle EVSClient shows a "permanent link to the sample".  You may be asked to provide that link as evidence for a test case.  The validation status and details appear at the bottom.

Finally, note that you can use the EVSClient application directly.  See these EVSClient tests:  https://gazelle.ihe.net/content/evs-client-tests

If your systems is a Consumer of objects (documents, images...), to access samples that have been uploaded by Creators, select Gazelle menu Connectathon-->Connectathon-->List of Samples

After selecting your system from the dropdown list, find the "Samples available for rendering" tab as follows: 

When you select a sample from the list, you will have access to sample details and can download the sample file(s):
