Building a consensus meta-data standard for actigraphy and light exposure data
summary
A team developed a consensus metadata standard for actigraphy (research-grade activity trackers) and light dosimeter data to capture details like device manufacturer, sampling rate, and participant instructions. The standard is implemented as a JSON Schema, is extendable to other time-series modalities (e.g., temperature), and was produced collaboratively by two volunteer research teams; the talk covers the development process and the challenges encountered from inception to finished standard.
