Standards Development

Scope

This document establishes a framework and methodology for model-based standards authoring, MBSA. MBSA improves the conciseness and completeness of future and existing standards by basing them on a formalized linkage of graphical and textual representations of a standard’s content to enable dual-mode comprehension. This document also serves as an example of a model-based standard. This document uses Object-Process Methodology, OPM, specified in ISO 19450, as the modelling language for the examples and method demonstration. While the MBSA approach can be applied using other modelling languages, this document applies OPM to demonstrate the methodology.

Purpose

This proposal is submitted to re-establish ISO 17649, Automation systems and integration — ModelBased Standards Authoring, under ISO/TC 184/SC 5. The project had already reached an advanced stage as ISO/DIS 17649 and had completed the enquiry process. The attached DIS text incorporates the disposition of comments and the editorial and technical changes intended to support progression toward final approval. The project was subsequently cancelled automatically due to procedural timeout following the enquiry stage. The cancellation was not the result of technical rejection, lack of market relevance, or lack of committee support. ISO 17649 addresses a recognized need in standardization: many standards rely heavily on free text and informal figures, which can lead to ambiguity, inconsistency, low traceability, and difficulty of implementation. The proposed standard establishes a model-based standards authoring methodology based on formal linkage between graphical and textual representations. This improves clarity, consistency, traceability, implementability, and dual-mode comprehension of standards. The need remains current and concrete. ISO/TC 184/SC 5 working groups are already applying the underlying model-based approach, including in work related to supply chain interoperability and integration. Re-establishing the project will preserve the technical consensus already achieved, avoid loss of several years of expert work, and enable ISO/TC 184/SC 5 to proceed efficiently toward publication.

The proposer therefore requests that the project be re-established using the attached mature ISO/DIS 17649 text as the base document, that the NP ballot be shortened to 8 weeks by committee resolution, and that the CD stage be skipped by parallel CIB resolution so that the project can proceed directly to DIS following NP approval.
