Darwin Core Quick Reference Guide

Official TDWG quick reference for all currently recommended Darwin Core terms. Lists each term with its identifier (URI), label, definition, comments, and examples, organised by class (Record-level, Occurrence, Event, Location, Taxon, Identification, MeasurementOrFact, ResourceRelationship). The Darwin Core standard provides a stable, common vocabulary for sharing biodiversity data and is the most widely adopted standard in biodiversity informatics. This guide is the primary reference for data managers mapping freshwater biodiversity datasets to Darwin Core, including terms essential for aquatic monitoring: waterBody, habitat, samplingProtocol, sampleSizeValue, and coordinateUncertaintyInMeters. Maintained by the TDWG Darwin Core Maintenance Interest Group.
