Abstract :
[en] [en] BACKGROUND: Light exposure significantly impacts human health, regulating our circadian clock, sleep-wake cycle and other physiological processes. With the emergence of wearable light loggers and dosimeters, research on real-world light exposure effects is growing. There is a critical need to standardize data collection and documentation across studies.
RESULTS: This article proposes a new metadata descriptor designed to capture crucial information within personalized light exposure datasets collected with wearable light loggers and dosimeters. The descriptor, developed collaboratively by international experts, has a modular structure for future expansion and customization. It covers four key domains: study design, participant characteristics, dataset details, and device specifications. Each domain includes specific metadata fields for comprehensive documentation. The user-friendly descriptor is available in JSON format. A web interface simplifies generating compliant JSON files for broad accessibility. Version control allows for future improvements.
CONCLUSIONS: Our metadata descriptor empowers researchers to enhance the quality and value of their light dosimetry datasets by making them FAIR (findable, accessible, interoperable and reusable). Ultimately, its adoption will advance our understanding of how light exposure affects human physiology and behaviour in real-world settings.

Open Access funding enabled and organized by Projekt DEAL. This project was financially supported by the Daylight Academy (DLA), a non-profit organization to promote the research on and use of daylight funded by the Velux Stiftung. M.S., M.M., K.W., C.B. and D.S. are members of DLA. During early parts of this work, G.H., C.B., C.S., N.S. and M.S. were supported by participating in the OLS-3 (Open Life Sciences) programme. During parts of this work, M.S. was supported by a Sir Henry Wellcome Postdoctoral Fellowship (Wellcome Trust, 204686/Z/16/Z), Linacre College, University of Oxford (Biomedical Sciences Junior Research Fellowship), and the MeLiDos project. J.Z. was supported by the MeLiDos project. The MeLiDos project (22NRM05 MeLiDos) has received funding from the European Partnership on Metrology, co-financed by the European Union’s Horizon Europe Research and Innovation Programme and by the Participating States. M.M. is supported by the Velux Stiftung. C.B. was supported by a grant for junior researchers by the University of Basel, Switzerland, and an Ambizione grant of the Swiss National Science Foundation. K.W.’s contribution was in part supported by the Knut and Wallenberg Foundation. C.S. was supported by the Belgian Funds for Scientific Research (FNRS). C.S. and G.H. were supported by a European Research Council, Grant (COGNAP‐GA75776). The funding sources had no role in the design of this study and will not have any role during its execution, analyses, interpretation of the data, or decision to submit results.
