ISO 10303-1 - Industrial automation systems and integration — Product data representation and exchange — Part 1: Overview and fundamental principles2021
ISO 10303 provides a representation of product information along with the necessary mechanisms and definitions to enable product data to be exchanged. The exchange is among different computer systems and environments associated with the complete product lifecycle, including product design, manufacture, use, maintenance, and final disposition of the product.

This document defines the basic principles of product information representation and exchange used in ISO 10303. It specifies the characteristics of the various series of parts of ISO 10303 and the relationships among them.

Reference ...
Component
    
    
A part or subassembly model that is assembled into an assembly or subassembly model.

Part, Assembly
Alternate Definitions ->
Conformance
    
    
precise, text definition of a characteristic required to be present in a conforming implementation

Characteristic
Data
    
    
Information represented in a formal manner suitable for communication, interpretation, or processing by human beings or computers.

Data Set
Alternate Definitions ->
Data Exchange
    
    
storing, accessing, transferring, and archiving of data
Digital Signature
    
    
result of a cryptographic transformation of data that, when properly implemented, provides a mechanism for verifying origin authentication, data integrity and signatory non-repudiation
Exchange Structure
    
    
computer-interpretable format used for storing, accessing, transferring, and archiving data

Data Exchange
Externally Defined
    
    
explicit identification of the definition given within another source

Note 1 to entry: That source provides all the information necessary to unambiguously recreate the element; the information can be referenced rather than recreated.

Information
    
    
facts, concepts, or instructions

Product Information Model, Information Model
Information Model
    
    
formal model of information

Note 1 to entry: In ISO 10303, an information model is based on the Object-relationship modeling technique that organizes the product data as represented in different system aspects.

Note 2 to entry: In ISO 10303, information models are developed using EXPRESS modeling language.

EXAMPLE ISO 10303-242.

Product Information Model
The product information model is an information model which provides an abstract description of facts, concepts and instructions about a product, such as a STEP Application reference model or STEP Application interpreted model. (cf NAS9300-003, 3.2.1)
