This standard adopts adding an ISA95 prefix to all ISA-95 defined terms that are used in this standard that are also defined by OPC. The <Term> is the terminology defined by ISA-95. This allows the terminology used in ISA-95 to be easily distinguished from terminology defined in OPC UA.

a concept that categorizes a modelling target defined as a Class in ISA-95 Part2.

Note: It is different than the concept of a Type defined in OPC UA OPC 10000-3, even though the OPC UA Type is also a concept to classify a modelling target and it is similar to a concept of class used in OOAD.

a concept that represents Equipment, Personnel, Physical Assets, and Material defined in ISA-95.

a concept that represents characteristics of a modelling target defined as a Property in ISA-95 Part2.

Note: The semantic of the ISA95Property is similar to Property defined in OPC UA, but the model structure is different since an ISA95Property may have a Reference to an ISA95TestSpecification and an ISA95TestResult and such References are not allowed in an OPC UA Property. An ISA95Property more closely matches an OPC UA Variable, which is allowed to have children.

a concept that represents an attribute of a modelling target defined as attribute in ISA-95.

Note: It is different from a concept of Attribute defined in OPC UA, where Attribute is a concept to represent information of a NodeClass. ISA95Attribute is represented as VariableType in this standard.
