To empower seamless healthcare interoperability through an open, community-driven integration engine that is accessible, extensible, and standards-based.

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.

• 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.

• 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.

• 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

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.

• Community-Driven Development – Innovation through global collaboration
• Vendor Neutrality – Free from proprietary constraints
• Security and Compliance – HIPAA/GDPR-compliant architecture
