ISO 13374-2:2007 details the requirements for a reference information model and a reference processing model to which an open condition monitoring and diagnostics (CM&D) architecture needs to conform. Software design professionals require both an information model and a processing model to adequately describe all data processing requirements. ISO 13374-2:2007 facilitates the interoperability of CM&D systems.
ISO 18435-3:2015 defines the profiling methodology to use the interoperability templates of ISO 18435‑2. These profiling methods describe the construction and the use of application domain matrix elements (ADMEs), application interaction matrix elements (AIMEs), and an open technical dictionary (OTD) to support the information exchange.
