This standard is an extension of the overall OPC Unified Architecture standards and defines an information model that conforms to the Common Object Models defined in ANSI/ISA-95.00.02-2010 Enterprise/Control System Integration – Part 2: Object Model Attributes standard, referred to as ISA-95 in this document. The Common Object Models describe the object model for Personnel Information, Role Base Equipment Information, Physical Asset Information, and Material Information as resources for manufacturing operations and controls, and is widely used in many industries for information exchange in Manufacturing Operations Management (MOM) systems. The international version of this ISA-95 standard is IEC 62264-2:2013, the Common Object Models in both are the same.

The Business To Manufacturing Markup Language (B2MML) is an open source XML implementation of the ISA-95 and IEC 62264 standards. The Business To Manufacturing Markup Language (B2MML) is used courtesy of the Manufacturing Enterprise Solutions Association (MESA International). B2MML is used as the de facto standard interface to exchange the contents defined in ISA-95. The OPC UA implementation will complement the existing B2MML implementations by providing a secure and reliable environment that is widely accepted in the manufacturing industries.

The modelling targets of this standard shall exist in an OPC UA Address Space. This standard does not consider the modelling targets that are identified in other standards or vendor specifications.
