Components

The Components hierarchy contains descriptors for the constituent parts of objects, including structures, images, and texts. In those instances where a descriptor refers to an element that may sometimes be a component and sometimes stand alone, it is placed in the single most suitable hierarchy. For example, "chapels", which are always rooms or spaces but may sometimes also be independent buildings, appears in the section of the Components hierarchy; "air conditioners", which are always equipment but may also sometimes be part of HVAC systems, appears in the Tools and Equipment hierarchy.Relation to Other Hierarchies: Descriptors for features that are not separable components, such as ornamental patterns and physical effects (e.g.g., "fluting", "wrinkles"), appear in the hierarchies of the Physical Attributes facet. Descriptors for items permanently installed into the fabric of the built environment (e.g. "altars") appear here as components, while movable articles used to furnish indoor or outdoor spaces are found in the Furnishings hierarchy.
