Data4Life releases Data2Evidence as open source: a new chapter for global health research

POTSDAM, Germany, April 2, 2025 /PRNewswire/ -- Data4Life, the nonprofit digital health organization, today announced the open-source release of its research platform Data2Evidence (D2E). With this move, Data4Life is equipping researchers and developers worldwide with powerful tools to integrate, manage, and analyze heterogeneous health data. By adopting an open-source strategy, the organization aims to foster scientific collaboration, accelerate innovation, and strengthen the interoperability of health data.

Open source for better research and greater transparency

Data2Evidence is a digital platform built around the OMOP Common Data Model (CDM), designed to streamline the standardization of health data. It enables seamless collaboration between research institutions and public health organizations by supporting interactive data integration, cohort-based exploration, and privacy-preserving data management.

The platform is flexible enough to meet the demands of a wide range of scientific use cases—from longitudinal studies to real-world evidence generation.

Open source, open science: driving innovation in health research

• Advanced visualization
   A customizable dashboard provides anonymized, aggregated insights and cohort comparisons to support exploratory analysis.
  
  
• Interoperability and scalability
   Based on OMOP CDM, the platform supports open standards, making health data easier to compare, reuse, and build upon.
  
  

Why open source matters

• Trust through transparency
   Open access to source code allows for independent review of security and privacy standards.
