Supporting standard data model mappings

摘要

Very little work has been done on specifying a standard mapping between the overlapping semantic specifications in the standardized data models used in architecture, engineering and construction (A/E/C, e.g., IAI-IFC and ISO-STEP standards). However, several companies have developed bespoke mappings from these standards into their design tools, and back out again. With this approach it is difficult to understand how complete their mappings are, and what assumptions are made in the development of the mappings. Yet for semantic mappings, as distinct from mappings over geometric representations, this has a profound implication for the correctness of the resultant data. In this paper the development of a suite of mapping support tools is discussed to illustrate the level of support required to ensure semantically correct mappings across data models.
