Open Science
Open Science is a set of principles and practices that aim to make scientific research from all fields accessible to everyone by opening up the processes of creating, evaluating, sharing, exploring and storing scientific knowledge, practices and perspectives, for the benefit of both scientists and society as a whole.
openJII
Our mission is to advance open science by sharing, integrating, and interpreting complex, large-scale datasets to uncover genetic linkages that influence photosynthesis. Through this collaborative platform, we empower researchers to identify photosynthetic limitations and their genetic controls across diverse crops and environmental conditions, driving innovations to enhance photosynthetic efficiency and agricultural productivity.
Our goals:
Collection of time series data
Store and manage photosynthesis data
Provide tools to analyse photosynthesis
Link real world sensor data to genomics and novel analytics and modeling
openJII is a non-profit, open-source platform supported by the scientific community.

Download the openJII app (Android only) to collect and analyze data in real time.
Researchers can develop analysis scripts that run on openJII and connect compatible community-developed sensors through documented interfaces. Learn about hosted analysis and sensor integration.
About JII
openJII is hosted and supported by the Jan IngenHousz Institute (JII), an open-science research institute working to understand and improve photosynthesis.
