Data Package
On this page
Metadata in GLEAM DP are expressed in a datapackage.json file. It follows the Frictionless Data Package specification and includes standard package-level metadata together with GLEAM-defined fields and resource structures tailored to light exposure and optical measurement research. Required properties are indicated with an asterisk *.
Dataset-specific metadata are organized into a set of related resources, including study, participant, device, dataset and reference resources, which are declared and linked within the data package.
