Overview
ISO 11748-3:2002 - Road vehicles: Technical documentation of electrical and electronic systems - Part 3: Application example - provides a concrete application example of the documentation guidelines defined in ISO 11748-1 and ISO 11748-2. The example is implemented using SGML (ISO 8879) and shows how document type definitions (DTDs) and document instances can be structured for automotive electrical/electronic system documentation.
Key topics and technical highlights
- SGML-based example: Demonstrates use of SGML (ISO 8879) to separate content, structure and layout, and to define document classes via DTDs.
- MSR DTD family: Illustrates MSR application profiles and DTDs used in the German automotive MSR initiative:
- MSRSYS.DTD - system-level descriptions (project data, part decomposition, architectures, connections, electrical/environmental/optical/mechanical characteristics)
- MSRSW.DTD - software specifications (data dictionaries, functional specs, calibration parameters)
- MSRNET.DTD - on-board network documentation (topology, interfaces, signals/messages)
- MSRREP.DTD - generic reports and change-management documents
- Link model and semantics: Consistent linking across DTDs supporting ID/IDREF, HyTime, and MSR semantic addressing so documents can be integrated into one database.
- Administrative and versioning data: Examples show administrative metadata and version control down to document fragments to support collaborative engineering.
- Documentation agreement & exchanges: Annex A provides a sample documentation agreement, document partitioning, exchange schedules, media formats (example: HTML/GIF tar-files on disk, photographic film for graphics), and management references.
- Practical SGML view: Annex A includes an SGML snippet and a flashing-system tutorial project illustrating part-types, views and document instances.
Applications and users
ISO 11748-3 is primarily useful for:
- Automotive OEMs and suppliers implementing standardized technical documentation for electrical/electronic systems
- System architects, technical authors and configuration managers creating DTDs or migrating to XML/SGML application profiles
- Engineering teams needing a template for documentation agreements, document exchange schedules and version-controlled document fragments
- Tool vendors and integrators building document databases, linking mechanisms and document-exchange workflows for vehicle electronics
