This section presents more details of the Factory Data Model in terms of OWL classes that are useful to instantiate factory models while going through the ontology modules.
The statistics module represents basic probability distributions via semantic characterization of key parameters. Representation of descriptive statistics.
The expression module formalizes Algebraic and Logical expressions. An expression can be decomposed in atomic, unary, binary, iterated binary, control flow expressions.
The osph module models Object States and Performance History, while integrating the ontology modules fsm, statistics, ssn, sosa, expression.
The ifcOWL ontology consists of three main classes: ifc:IfcContext, ifc:IfcObject, ifc:IfcTypeObject.
The following table lists some subclasses of ifc:IfctObject that can be exploited to model a factory. If available, a subclass of ifc:IfcTypeObject is paired with the corresponding sublcass of ifc:IfctObject, as it can be exploited according to the object typing pattern.
ifc: prefix stands for https://standards.buildingsmart.org/IFC/DEV/IFC4/ADD1/OWL#

The factory module specializes IFC_ADD1 and controlSystem modules with definitions related to production processes, part types, manufacturing systems and machine tools.
The following tables list some subclasses of ifc:IfctObject that can be exploited to model a factory. If available, a subclass of ifc:IfcTypeObject is paired with the corresponding sublcass of ifc:IfctObject, as it can be exploited according to the object typing pattern.
