Data is Plural: “The Getty Vocabularies, published by the Getty Research Institute, “contain structured terminology for art, architecture, decorative arts, archival materials, visual surrogates, art conservation, and bibliographic materials.” They provide definitions, relationships, translations, and disambiguations for a broad range of terms and entities. Their Art & Architecture Thesaurus, for example, describes 57,000+ generic concepts (e.g., lithography), while others focus on artist names, cultural objects, and geographies. The records are available several ways, including bulk downloads. [h/t Lynn Cherny]”
