This document provides a taxonomy of tags for members of the LANDInG CoP to use when adding resources to their libraries. It outlines 11 main categories for tagging resources, including measurements and methodologies, promising practices, barriers to equity, organizational settings, training environments, disciplines, demographics, COVID-19, learner levels, and geographic application. Each category contains multiple sub-tags to further classify the resources. Members are encouraged to use multiple tags for each resource when applicable.
