Semantic Mapping Between IAI ifcXML and FIATECH AEX Models for Centrifugal Pumps



E F. Begley, Mark E. Palmer, K A. Reed


This report describes a semantic mapping between two extensible markup language (XML) specifications describing a single type of equipment that is used in heating, ventilation, air conditioning, refrigeration (HVAC/R) and other types of systems: the centrifugal pump. The first XML specification is called ifcXML and represents the information content of the Industry Foundation Classes (IFC) as defined by the International Alliance for Interoperability (IAI). The second XML specification, AEX, is the product of a FIATECH project to define a language for Automating Equipment Information Exchange.
