Existing engineering data models provide various means of representing, organizing and linking information about constructed facilities in a computer-integrated environment. However, they often fail to recognize fundamental and important interrelations between the spatial and non-spatial attributes of facility components. Spatial information is modeled by specialized geometric representation schemes and often shared across disciplines; while non-spatial information is captured as attribute-value pairs in taxonomies of attribute classes that an discipline-specific. In this paper a unified model is presented where a data object represents an abstraction of a physical object in a constructed facility. A data object has two primary types of attributes: spatial and non-spatial. Based on this model, two key issues are explored: the computer-based representation of spatial and non-spatial attributes of physical objects; and the definition and retrieval of facility information in and from a common information repository. Information modeling and management concerns, such as classification of information, procedural access to information, and data encapsulation are examined for both of these issues in an object-based framework.
