Table of Contents
Mission Statement
To empower seamless healthcare interoperability through an open, community-driven integration engine that is accessible, extensible, and standards-based.
Overview
The Open Integration Engine Project is an open-source initiative committed to advancing healthcare interoperability. Building upon the foundation of Mirth Connect, a widely adopted integration engine, this project aims to provide healthcare organizations with a robust, flexible, and cost-effective solution for connecting disparate systems and facilitating efficient data exchange.
Why Open Integration Engine?
-
Open Source Advantage
Transparency, innovation, and collaborative development within the healthcare IT community.
-
Healthcare-Focused
Designed to address the unique challenges of healthcare data integration, supporting standards such as HL7, FHIR, and DICOM.
-
Extensible and Customizable
Modular architecture for customization and expansion to meet evolving needs.
Core Features
-
Data Transformation and Mapping
Convert between HL7, JSON, XML, and other formats to ensure cross-system compatibility.
-
Message Routing and Filtering
Route messages using flexible, rules-based logic to streamline workflows.
-
Custom Scripting and Connectors
JavaScript-based scripting and support for protocols like HTTP/S, FTP, and database connectivity.
-
Real-Time Monitoring and Alerts
Visual tools for tracking message flow, performance metrics, and setting up alerts.
Who It’s For
- Integration Engineers – Looking for a flexible, open platform for managing interfaces
- Health IT Teams – Connecting EHRs, LIS, RIS, and other healthcare systems
- EHR Vendors – Enhancing interoperability within their products
- Researchers – Requiring reliable, standards-based integration tools
Building from Source
The build is driven by Gradle through the committed wrapper; the only prerequisite is JDK 17 (see .sdkmanrc):
./gradlew build # full build + tests; distribution lands in server/setup
./gradlew clean build dist # release form, plus extension zips in server/dist
On Windows use gradlew.bat. See CONTRIBUTING.md for the full command reference, the dependency policy, and how to run the server for development.
Project Values
