Digital Construction Entities

Something that acts in the asset role

A role in which an entity acts as an asset

An entity that forms a part of an existing or designed building

Category is a labeling of an entity the associates it with some defined class of things. For example, an object can be associated with a particular class in a classification system such as OmniClass, UniFormat, CoClass, or Talo2000.
