DHIS2 Core vs OpenMRS Core

DHIS2 is a large open-source health information management system, written in Java, containing the service layer and web API.

It is developed by the HISP programme at the University of Oslo and released under BSD-3-Clause.

OpenMRS is an open-source medical record system platform whose Java API and web application form the foundation for national electronic medical record systems in several African countries, including Kenya's KenyaEMR. It supports patient records, encounters and clinical data in low-resource settings. It is released under the Mozilla Public License 2.0.
