OpenMRS EMR Key Repositories.
The OpenMRS Core is the foundational heart of the entire OpenMRS system. It’s the essential, minimal platform upon which all features, modules, and implementations are built.
The module exposes the OpenMRS API as REST web services. If an OpenMRS instance is running the webservice.rest module, other applications can retrieve and post certain information to an OpenMRS database.
The OpenMRS FHIR2 Module is the crucial component that allows OpenMRS to communicate and share clinical data with other healthcare systems using the modern Fast Healthcare Interoperability Resources (FHIR) standard.
This is a monorepo containing the core packages for the O3 frontend. These packages handle cross-cutting concerns such as the configuration and extension systems, the core framework, global state management, the styleguide, and more.
This project holds the build configuration for the OpenMRS 3.0 reference application, found on https://dev3.openmrs.org and https://o3.openmrs.org.
