Cataloging Cultural Objects (CCO) provides guidelines for cataloging physical and digital cultural works. It outlines key elements to include, such as object name, creator, and physical description. CCO recommends using controlled vocabularies from authorities. It was created jointly by museums, libraries, and archives to promote consistent and accessible cataloging of cultural works. CCO can be combined with other metadata standards like VRA Core and CDWA. It provides a flexible yet standardized approach to describing cultural objects and images.
