Welcome to the official home of the Open Health Stack (OHS) Software Foundation, an umbrella project hosted within the Linux Foundation.
The OHS Software Foundation is dedicated to providing open-source building blocks that enable developers to build "next-gen" digital health solutions; that promote interoperability (through HL7® FHIR® standard), are designed for low-resource settings (e.g. off-line capable, local and cloud deployable) and that enable AI for Global Health.
🏗️ Software Foundation Status: Formal Formation Phase The OHS Software Foundation is currently in the formation phase. We have transitioned the technical assets and are finalizing the projct charter and governance framework. We welcome interested parties.
🚀 Core Projects The following core components have been transferred from Google to the OHS Foundation:
- Android FHIR SDK: A set of Kotlin libraries for building offline-first Android health apps.
- FHIR Gateway: A secure proxy for managing access to FHIR servers.
- FHIR Data Pipes: Tools for moving FHIR data into analytics engines like BigQuery or ClickHouse.
🏗️ Projects under development
- Kotlin-fhir: A lean and fast implementation of the HL7® FHIR® data model on Kotlin Multiplatform.
- Kotlin FHIR SDK Libraries (kotlin-fhir-engine, kotlin-fhir-data-capture, kotlin-fhir-workflow, kotlin-fhir-knowledge-manager): A fully rewritten set of kotlin multiplatform FHIR SDK Libraries to enable building FHIR based apps for Android, iOS and web. Leverages the kotlin-fhir models.
- KMP FHIRPath: Kotlin multiplatform implementation of the FHIRPath specification
- OHS Player: A "reference toolkit” to make it easier to build and deploy (x-platform) "next-gen" digital health solutions (leveraging FHIR standards and AI hooks)
- OHS Labs: Set of experimental projects to explore new features that leverage AI or help digital health developers build with AI
🤝 Get Involved We are looking for contributors, health systems, and technology partners to help shape the future of open-source health infrastructure.
Join the Community If you or your organization are interested in joining the foundation, contributing to the roadmap, or participating in a Special Interest Group (SIG), we would love to hear from you.
