Announcing the Release of the Zenysis Open Source Platform: Harmony

Hi OpenHIE colleagues, I’d like to share an exciting announcement on behalf of Zenysis (

Zenysis is excited to announce the release of Harmony, a scalable data integration and analytics platform for global health and development that makes the primary functionality of the Zenysis technology available under an open source license.Harmony helps make sense of messy data by transforming, cleaning and enriching essential health data, including from sources typically encountered in a development setting like DHIS2, OpenLMIS, DHS surveys, geospatial, financial, HR, climatological data and more. With Harmony, data from these systems is available within a single point of access, giving decision-makers a complete picture of their data through triangulated queries and customizable visualizations and dashboards.

Harmony is a momentous step for Zenysis and represents our commitment to key pillars of the Principles for Digital Development by developing software that is open, scalable and sustainable in development and humanitarian settings. By making our integration and analytics functionality available open source, countries and their partners have the tools they need to remove data from siloes across the entire ecosystem of information systems and break down barriers to effective data use.

Technical Overview
Harmony comprises an integration framework that can ingest and process data from almost any structured data source as well as an analytics and visualization tool that allows for advanced querying and customizable visuals. The release is also accompanied by guidance describing processes for preparing data to be ingested by the platform as well as processes for setting up open source dependencies such as Druid and PostgreSQL.Harmony will follow a six-month release schedule which will include bug fixes, new feature development and more. Contribution guidelines to Harmony are included in the README on GitHub.
