ISO 18542-2:2014

Overview

ISO 18542-2:2014 - Road vehicles: Standardized repair and maintenance information (RMI) terminology, Part 2 defines the implementation requirements for systems and organizations that manage the agreed RMI terminology. It specifies the technical requirements for a Terminology Management System (TMS) and the responsibilities of a Registration Authority (RA) that maintains and publishes the agreed terminology via a Digital Annex (DA). The standard supports EC Mandate M/421 and is intended to facilitate searching of Vehicle Manufacturer (VM) RMI by Independent Operators (IOs).

Key topics and technical requirements

ISO 18542-2 focuses on practical system and process requirements rather than on the terminology content itself. Major technical topics include:

• Overall system architecture
  • Conceptual architecture and data/role models required for a COTS TMS.
• System infrastructure
  • IT infrastructure components, database management and storage, and security requirements.
• User interface
  • Graphical user interfaces, web access and other interface considerations for editors and consumers.
• Data management
  • Meta-object models, data exchange formats, data management services and reporting capabilities.
• Application and workflow management
  • Workflow stages such as proposal, evaluation, review, translation, release and publication of agreed terms.
• Operation and support
  • Availability, system administration, change and release management, and support arrangements.
• Registration Authority (RA)
  • RA responsibilities for controlling the Digital Annex IP, publication, and maintaining the agreed terminology lifecycle.
• COTS TMS expectations
  • Use of a Commercial-Off-The-Shelf terminology management system as a backend repository with workflow support.

Practical applications

ISO 18542-2 is used to ensure consistent, secure and auditable management and publication of automotive RMI terminology. Typical applications:

• Enabling independent repairers and service providers to reliably search VM RMI.
• Guiding vehicle manufacturers (VMs) and their IT teams in implementing compliant RMI terminologies and interfaces.
• Informing software vendors and system integrators who supply or host COTS TMS solutions.
• Defining governance and publication processes for a Registration Authority and maintenance agency.
• Supporting compliance with EC Mandate M/421 and related type-approval access requirements.

Who should use this standard

• OEM technical leads and RMI product owners
• TMS vendors and integrators
• Registration Authorities and terminology governance bodies
• Independent repair networks and automotive aftermarket service providers
• Regulatory and standards implementation teams working on mandate M/421
