These are the AID user group meeting minutes for the WGM held in May 2014.

Sunday Q3/Q4, Minutes

  1. Administrative
    • Call to order at 12:45
  2. Supporting FHIR dcuments and REST using BizTalk 2013 (Howard Edidin, US)
    • They have developed solution using Microsoft BizTalk 2013 to demonstrate the use of the REST Adapter to connect to a FHIR Server. XML Messages (Inidvidual Resources and FHIR documents) will be routed to and from both SharePoint and / or Azure Services.
    • We aim to demonstrate the use of BizTalk 2013 both as a FHIR Server and consumer. The solution uses Azure BizTalk Services in order to provide a Server public interface, and Office 365 as a client. The complete solution supports the FHIR security specs.
  3. Development aspects of a Windows Phone App (Brian Postlethwaite, AU, see for slides)
    • His talk will focus on implementation aspects - see video for a prior (non technical) presentation by Brian.
  4. A web-based FHIR profile editor (David Hay, NZ)
    • David has created a basic web-based profile editor, not as elaborate or complete as Forge (for example there is no slicing), built for internal use at Orion health where the main requirement is the building of extensions. It also creates a simple user interface that allows test data to be entered and subsequently queried for

  1. Administrative agenda items
    • Peter calls to order at 13:45
  2. A DECOR based c# code generator (Justin Fyfe, Mohawk College, CA)
    • ART-DECOR is a toolkit designed to express constraints on v3/CDA models, it is compliant with the new Template standard as defined by HL7 International. Justin has been working on a c# toolkit based on the contents of DECOR. He'll provide a status update as well as some examples.
    • Justin presented Sherpa. A system that complements Everest.
    • Link to demo is here:
  3. Everest is the dot NET and JAVA package that can take MIF files and develop application ready DLL or JAR files that have all the classes needed for the back end of a CDA RIM based application.
    • Templates for CDA have been written in PDF format for human consumption. Most template documents referred to other PDF documents and it was nearly impossible for an implementer to know what was required to comply with a set of templates.
    • The template group defined a Template DSTU file format that is machine readable. ART DECORE is able to parse a template file into a DECORE template. ART DECORE is created by NICTIZ in the Netherlands. Once it is in this format it is possible to use the template within Sherpa to programmatically add the constraints to the Everest classes that have been created by Everest from parsing a MIF file. The Sherpa software has a validate function that will check the generated and constrained classes and generate errors and instructions for the implementor until the Everest classes are complient with the templates. Once this is output as a DLL or JAR file, it is ready to be handed to a GUI implementer and can be used to generate end user focused software for the automatic creation of template compliant CDA documents, or even other HL7 V3 RIM based structures.
    • Everest can parse MIF and create JAVA or dot NET classis. But you still had to do work like reading the PDF templates, read the rule in PDF and then type in the code to enforce the constraint.
    • An automated way of adding these template defined constraints to the raw MIF defined classes was needed. The new software the SHERPA template compliler can take ART-DECORE templates and use them to programmatically generate the constrained CDA classes in C# (JAVA version planned).
  4. ART-DECOR (Kai Heitmann)
    • A tool which can parse in CDA and other V3 templates if they are in the form of the Templates DSTU. You can edit or even create new templates de novo. You can export templates, but the payload export is an ART-DECOR format template. This machine readable format can be parsed into the Everest Sherpa described above. The result from this stage is a completely template compliant constrained CDA in either dot NET or JAVA format. This is exported as a DLL or JAR file. Once this file is created it can be given to a UI designer who can make the final user facing application. The UI designer does not have to understand any HL7 or V3 or Templates. He only has to deal with getters and setters.
    • Creation of templates especially CDA. Collaborative platform can work with different domain experts, architects, clinicians, terminologists. Output is HL7 Template DSTU.
      • Is also a template repository. Has CCDA 1.1.
      • ISO schematron generator.
      • FHIR profile import/export functions and profile editor (under investigation)
      • RESTful services to get various artefacts.
      • Can reference value sets for terminology.
      • Can reference existing CDA templates.
      • Can import from MIF files.
      • Can generate UIs from ART DECOR
