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
