scope:

ISO 18542 is structured into 2 parts: ? Part 1: General information and use case definition - this defines a framework and a process for agreeing terms ? Part 2: Standardized process implementation requirements, Registration authority - this defines the process implementation requirements for a Terminology Management System and for a Registration Authority with a Digital Annex. The basic purpose of ISO 18542 Parts 1 and 2 is to facilitate searching by Independent Operators (IOs) of Vehicle Manufacturer (VM) Repair and Maintenance Information (RMI) websites. This part of the standard represents Part 2 of ISO 18542 and specifies: ? the technical requirements that must be met by the Terminology Management System [TMS] that will be used to manage and store the 'Agreed RMI Terminology' ? the requirements for the Registration Authority [RA] (i.e. the agency responsible for maintaining and publishing the 'Agreed RMI Terminology') ? the framework and process for creating 'Agreed Terminology' is the subject of ISO 18542-1 [i.e. Part 1]. ? the target audience for Part 2 is a technical one, and focused on those responsible for the implementation of mandate M/421. Part 2 of the Standard is predicated by some key decisions and concepts that need to be understood in order to fully appreciate its intent. From the outset it was determined that a set of 'Agreed Terms' would be used by an IO to search a VM's RMI. The phrase 'Agreed Terms' is used rather than 'Standardized Terms' because the terms should not be 'standardized' in the established sense. The standardization process is lengthy and the need to have terms available for searching in a short timescale means such an approach is inappropriate. The process by which a panel of expert terminologists agrees and reviews terms is systemized and central to ISO 18542 Part 1. The provision of the agreed Automotive RMI Terminology itself is outside the remit of this standard and therefore outside the scope of this document. Rather, it is foreseen that the agreed Automotive RMI Terminology will follow a lifecycle beyond the timeframe of the standard and be dependent upon the work of a Registration Authority, a Terminology Review Group for its creation and management, and of a Digital Annex for its publication. For the development of the Digital Annex existing standards will be reviewed and elements included where appropriate and practical. In order to effectively maintain the 'Agreed Terminology', it has been determined that a Commercial-Off-The-Shelf (COTS) Terminology Management System (TMS) is required. The COTS TMS functions as a 'back-end' database repository with a workflow element that will ensure 'Agreed Terms' are created, and managed in line with the standardized process outlined in Part 1. ? It is anticipated that there will be a maintenance agency which will be responsible for overseeing the procurement and hosting of the COTS TMS. ? A Registration Authority (RA) controls the IP for the Digital Annex (DA) and is responsible for managing and publishing the content of that DA. ? The maintenance agency for the Commercial-Off-The-Shelf Terminology Management System (COTS TMS) and the Registration Authority (RA) for the Digital Annex (DA) may be a single organization.
