Overview

ISO/IEC 18012-2:2012 - Information technology - Home Electronic System (HES) - Part 2: Taxonomy and application interoperability model - provides a standardized taxonomy and an application-level interoperability framework for smart-home and HES devices. The standard defines a common way to describe application objects, events, properties and primitive actions so products from multiple manufacturers can interwork at the application layer (above the OSI stack). It supports single- and multiple-implementation HES networks, connected devices and applications, and both automatically and manually configured devices and clusters.

Key topics and technical requirements

• Application interoperability model: Specifies how applications map and interoperate using a common model that sits above ISO/IEC 7498-1 (OSI) layers.
• Taxonomy and classification: Standardized classification of application domains, functional objects and application objects to enable unambiguous descriptions across systems.
• InterWorking Function (IWF): Describes the preferred interoperability approach (generic gateway/IWF) versus multiple protocol-specific gateways; applications implement an IWF to translate to/from the common model.
• Interaction model elements:
  • Application objects and functional objects
  • Binding map for mapping object interfaces between systems
  • Events and an event bus for event propagation
  • Object schema (base objects, control/sensor/actuator objects)
  • Property primitives including data types, unit types and action primitives
• Conformance and descriptive methodology: Requirements for representing application objects and mapping them for transparent interoperability.
• Annex material: Examples and schema definitions (e.g., lighting application example, base object schema, schema extensions, notes on interoperability).

Practical applications

ISO/IEC 18012-2 is intended to facilitate practical, vendor-neutral interoperability for:

• Smart lighting, heating, energy management, audio/video control and home security applications
• Integrations where devices from different ecosystems must cooperate without replacing underlying protocols
• Systems requiring automated and manual configuration of device clusters and groups

Who should use this standard

• Product designers and manufacturers developing HES/smart-home devices
• System integrators and platform architects building gateways or IWF implementations
• Standards bodies and test labs creating interoperability profiles and certification criteria
• Software developers implementing application-layer mappings or device models for IoT/smart-home solutions

Related standards

• ISO/IEC 7498-1 (OSI reference model) - referenced as the lower-layer context
• ISO/IEC 14543 family - cited in the development background for HES network control
