The Object Genres hierarchy contains descriptors that are common to various contexts and may apply to more than one of the other hierarchies in the Objects facet. For example, the descriptor "reproductions", which appears here, may be applied to many object types, from "doorknobs", which is in the Components hierarchy, to "altarpieces", which appears in the Visual Works hierarchy. Also included are descriptors for broad classes of objects or images to which specific object types, which are found in other hierarchies, may or may not belong depending on the particular context. For example, "photographs" (in Visual Works) can be variously considered to be "documents" or "works of art" (descriptors that appear here), depending on the circumstances; or "cups" (in the Containers hierarchy) can be variously considered as "antiques", "art objects", or "collectibles" (descriptors that appear here), again depending on the circumstances. Also included here are descriptors that refer to an object by its form, and that form is so generic that it does not fall into the more specific scope of any other hierarchy in the Objects facet, such as "chains".Relation to Other Hierarchies: Descriptors for more specific object types, including structures, images, and texts (e.g.g., "chairs", "churches", "portraits", "transcripts"), appear in other hierarchies of the Objects facet. Descriptors for constituent parts of other objects (e.g., "handles") are found in the Components hierarchy, and those for items used as materials to form structures, images, or other objects (e.g. "brick") are found in the Materials hierarchy.
