ICONCLASS is a controlled classification system for the subjects and content of images, especially in museums, libraries, and broader cultural-heritage collections. Its online browser supports subject access to image collections and links the classification system to related documentation and services.
ICONCLASS is maintained by the Henri van de Waal Foundation. Its data files are
published under CC0 in the iconclass/data GitHub repository, and individual
concepts are available as linked open data (SKOS RDF/XML, JSON-LD, and JSON) by
appending a file extension to a notation URI. There is no single bulk SKOS dump.
The owned browser product above represents the canonical entry point for the live ICONCLASS resource. The OBO-DB-Ingest derivatives are preserved here as propagated downstream products that transform ICONCLASS for ontology-oriented integration workflows.
