Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 56: Integrated generic resource: State (ISO 10303-56:2005). This part of the STEP family specifies the integrated generic resource that defines the concept of "state" and the data elements and relationships needed to represent state information within STEP-based product data models.

Abstract

ISO 10303-56:2005 defines the integrated resource "State" used in the ISO 10303 (STEP) architecture. The standard covers the definition of a state, the necessary attributes and conditions for a state to exist, relationships between states, assignment of states to items, and the recording of state history. It provides the data model necessary for consistent capture and exchange of state-related information across product lifecycle applications.

Scope

This part specifies the "State" integrated generic resource for STEP. Its scope includes formalizing what constitutes a state, the attributes and contextual information required for a state to exist, mechanisms to express relationships among states, methods to assign states to product-related items or entities, and provisions for recording and exchanging state history. The resource is intended to be used as a reusable building block within STEP application modules and APs to represent lifecycle and state-related information consistently.

Key topics and requirements

• Formal definition of "state" as an integrated generic resource in the STEP architecture.
• Data elements and attributes required to represent the existence and properties of a state.
• Definitions of relationships between two or more states (e.g., precedence, transitions).
• Rules and mechanisms for assigning states to items or entities in product data models.
• Representation of state history (time-stamped records of state changes).
• Schema-level definitions intended for implementation in STEP EXPRESS modules and STEP modules (typical for STEP resources).

The above topics are the core modelling and exchange concerns addressed by the resource; STEP resources are normally delivered as data model definitions intended for inclusion in larger application protocols and modules.

Typical use and users

ISO 10303-56:2005 is used by systems and engineers that need to represent, store, or exchange lifecycle/state information about products or components: CAD/PLM/ERP integrators, data architects, software developers implementing STEP imports/exports, system integrators, and organizations managing configuration, maintenance or production state records. It is typically consumed as an EXPRESS data resource by implementers building or extending STEP application protocols or proprietary data exchanges.

Related standards

ISO 10303-56 is one part of the ISO 10303 (STEP) family. Related and commonly referenced parts include foundational parts such as ISO 10303-1 (overview and fundamental principles), Part 11 (EXPRESS language reference), Part 21 (STEP-File), and many application protocols (APs) that reuse resources like Part 56. The 2005 edition of Part 56 has been withdrawn and a newer edition (ISO 10303-56:2019) is available as its replacement. Implementers often consult the STEP Module and Resource Library (SMRL) and relevant APs (for example AP 203 / AP 242 for CAD data exchange) when applying the State resource.

FAQ

Q: What is this standard?

A: ISO 10303-56:2005 is the STEP integrated generic resource that defines how "state" is represented for product data exchange within the ISO 10303 framework. It provides a data model for representing states and their relationships.

Q: What does it cover?

A: It covers the definition of state, the attributes and conditions required for a state to exist, relationships between states, assignment of states to items, and recording of state history for exchange between systems.

Q: Who typically uses it?

A: Typical users include PLM and CAD integrators, data architects, software developers implementing STEP imports/exports, systems engineers, and organizations managing configuration, maintenance, or production states. It is used where consistent machine-readable representation of state information is needed across systems.

Q: Is it current or superseded?

A: The 2005 edition (ISO 10303-56:2005) has been withdrawn; a newer edition (ISO 10303-56:2019) supersedes it. For current implementations and purchases, consult the latest ISO catalogue entry or national standards body.

Q: Is it part of a series?

A: Yes. It is one part of the ISO 10303 (STEP) family of standards, which is a modular set of parts covering data representation, implementation methods, resources, modules and application protocols for product data exchange.

Q: What are the key keywords?

A: Key keywords are: State, integrated resource, STEP, ISO 10303, product data exchange, EXPRESS schema, state history, state assignment, lifecycle state.
