Full title and description

St ISO TS 10303-1678-2006 — Industrial automation systems and integration — Product data representation and exchange — Part 1678: Application module: Functional decomposition with nodal representation to packaged mapping. This technical specification defines data constructs and relationships for mapping sets of nodes in a hierarchical functional network to single nodes in a non-hierarchical (physical/packaged) network for assembly design and packaged mapping.

Abstract

ISO/TS 10303-1678:2006 specifies an application module within the ISO 10303 (STEP) family that represents the information required to assign a set of functionally related nodes in a directed hierarchical network to a single node in a physical (non-hierarchical) network. The module covers the representation of node sets that satisfy a transitive-closure property and the rules for mapping those sets to packaged or physical nodes in assembly design contexts.

Scope

The scope of ISO/TS 10303-1678:2006 is the definition of an application module to describe mappings between a set of nodes in a functional hierarchical network and a single node in a physical (non-hierarchical) network for assembly designs. It covers representation constraints (for example transitive-closure of node sets and directed graph representations), the assignment relationships between functional and physical nodes, and the packaged-mapping constructs required to record these relationships within STEP application schemas.

Key topics and requirements

• Representation of node sets in hierarchical functional networks (directed graph model).
• Definition and enforcement of transitive-closure properties for node membership in a mapped set.
• Mapping semantics: assignment of a functional node-set to a single physical/packaged node.
• Data constructs needed to record mappings for assembly and packaged design workflows.
• Interoperability requirements for exchanging mapping information between CAD/PDM/CAM systems using STEP.

Typical use and users

This application module is used by implementers of STEP-based data exchange and product-modeling tools that must represent the relationship between functional decomposition models and their packaged/physical counterparts. Typical users include CAD/CAM developers, electronics and assembly design engineers, systems integrators, PDM/PLM software vendors, and standards engineers who implement or validate STEP schemas and translators for assembly mapping and packaged representations.

Related standards

Part of the ISO 10303 (STEP) family. Related application modules and parts in the 16xx–17xx range address complementary modeling concerns (for example other functional-decomposition and node-allocation modules, physical node allocation modules, and related application modules in the ISO/TS 10303 series). See adjacent ISO/TS 10303 application modules (e.g., other 167x parts) and higher-level STEP application protocols for integration into larger APs or domain schemas.

FAQ

Q: What is this standard?

A: ISO/TS 10303-1678:2006 is a STEP application module (Technical Specification) that defines how to represent mappings from sets of nodes in a hierarchical functional network to single nodes in a packaged/physical network for assembly design.

Q: What does it cover?

A: It covers the data structures and constraints necessary to express node-set membership (with transitive-closure properties), directed graph representation of the functional network, and the semantics for assigning those node sets to a single physical node in non-hierarchical network models used in packaged or assembly mapping.

Q: Who typically uses it?

A: CAD/CAM/PLM/PDM software developers, electronics and assembly design engineers, systems integrators, and standards implementers who need to exchange or persist mappings between functional decompositions and physical/package representations.

Q: Is it current or superseded?

A: The specification was published in December 2006 (Edition 1) and has been subject to ISO systematic review cycles; the entry shows it remained published and was confirmed during reviews (most recently in the ISO review cycle). Users should check national/ISO catalogues or the ISO database for the absolute current lifecycle status before purchase or formal compliance work.

Q: Is it part of a series?

A: Yes — it is one application module within the ISO 10303 (STEP) family of standards. The 10303 series includes many related parts (application modules, application protocols, and integrated resources) that collectively support product data representation and exchange.

Q: What are the key keywords?

A: Functional decomposition, nodal representation, packaged mapping, ISO 10303, STEP, node mapping, hierarchical network, assembly design.
