The OHIE’19 Hackonnect-a-thon is scheduled for Friday 8th November.

The OpenHIE Connectathon is a merger of two exciting types of meetings. This is a technical space for software teams and architects to engage and get their “hands-in” or “on” OpenHIE itself and see it materialised. Combining the principles of a connectathon and a hackathon we are excited to provide a space for teams to connect their existing tools to OpenHIE workflows and use-cases as well as give the community an opportunity to propose low hanging fruit use cases for the groups to work on. Recognising that many attendees may be new to OpenHIE there is no better way than actively engaging in designing, developing, configuring, implementing and connecting to an OpenHIE architecture to learn the fundamentals and build the relationships that you will need going forward.

Review of OHIE ‘18 Hackonnnect-a-thon


The attendees of the Hackonnect-a-thon are aiming to:

  • Connect existing tools to OpenHIE foundational registries
  • Learn how to implement workflows within their tools
  • Jointly work together to implement common use-cases within an OpenHIE architecture
  • Self-organise into learning sessions and create breakaway groups to discuss topics / show ideas

So what does this really mean/look like?

We are looking forward to the attendees (that is you, the participant) bringing their technical strengths to the table and bringing their systems to engage with others in the field. These sessions are focused at providing the space for the architects, the analysts, the developers and the integrators within the communities to meet and discuss how to solve active problems as well as start on the fundamentals of connecting systems. We are expecting a combination of the following to emerge:

  • Focused technical discussions around how best to engage with the deeper aspects of data exchange on a fundamental standards level and workflows.
  • Generating sequence diagrams and talking about what data systems curate and what would be available in the other systems and documented models and technical specifications to get it there.
  • Bringing your technical questions and started projects/code to any persons representing tools and technologies and engaging with them and others on how best to architect and develop the solution.
  • Bring your code and application and your development skills to the table and try to connect to systems that are present and possibly consume an OpenHIE workflow and share data with other system.
  • Learn more about the technical nature and how to model things in FHIR and/or how others have done it.
  • Design decisions that impact scale and speed as wells as how different implementers select different development patterns and architectures to solve their challenges.

What will be available to connect to and test against?

This space is a technical space and we encourage participants to "put their hands up" as to what they will be brining and what they will be making available to the participants to engage with. Depending on the number of participants we are considering scheduling a lightning session where groups can rapidly (5min/5 slides) present their tools as an intro. Currently the following teams and tools have put their hands up to be at the event and have technologies available.

HIE Component Tooling

Component GroupTool / SolutionOrganisation / ContactDescriptionOnline Demo/Sandbox
IOLOpenHIM ( Health Systems (

The OpenHIM is an interoperability layer that facilitates OpenHIE workflows. It allows easy configuration and setting up of channels and endpoints that allow systems to connect and exchange information. The use of mediators allows implementer/developers to add logic and custom flows to the channels. This is the current reference technology for the IOL community of OpenHIE.

Connectathon offering:

The OpenHIM will be setup and available for teams to create their own channels and the Jembi team be available to advise of how mediators and additions can be made.

SHRHEARTHJembi Health Systems ( )

HEARTH is Jembi's HL7 FHIR server that serves as an SHR on many of Jembi's internal projects. This FHIR server allows for FHIR resource management and has been used in multiple ways to manage more than just patient health data; such as patient management, facility mangement etc.

Connectathon offering:

HEARTH will be setup and available for teams to leverage and engage with the endpoints that include the storage and retrieval of FHIR resources from the tool





TSOpen Concept Lab (OCL)Regenstrief/Apelon

OCL provides cloud-based community-driven terminology management. OCL lowers implementation barriers by 1) providing access to major terminologies, such as the Columbia University eHealth Laboratory's interface terminology (CIEL, utilized in OpenMRS) and other international standards like ICD-10 and 2) supporting standards based operations to enable interoperability.

Connectathon offering:

OCL will be available for teams to utilize on various levels, from exploring how standardized terminologies and indicators can be represented to testing out the REST API and initial FHIR Terminology Services.


HIE Use Cases

Name / OutlineTools / Solution UsedOrganisation / ContactDescriptionOnline Demo/Sandbox

We ask each team to setup their own tools in the cloud and or locally on their own hardware and bring access details to the meetings.

Current Challenges

Taking into account systems and teams attending we are looking for groups and members to list out the current challenges that they are posing to the attendees. Please add your challenges/hacking ideas below


Lightning Talks

Lightning talks are a 5-10 min presentation that allows you to present your challenge, product, tool etc to the technical community. The goal is to get your ideas out into the forum and call persons to chat to you during the event. Please put down your topic and a description of what it is about and your details so that we can schedule the talks. If you are looking for a slide guideline it is max 5 slides (prefer 1-3).
