| ISO 10303-1 - Industrial automation systems and integration — Product data representation and exchange — Part 1: Overview and fundamental principles | Reference | 2021 |
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.
| A part or subassembly model that is assembled into an assembly or subassembly model. |  |
| precise, text definition of a characteristic required to be present in a conforming implementation |
| Information represented in a formal manner suitable for communication, interpretation, or processing by human beings or computers. |
| storing, accessing, transferring, and archiving of data |
| result of a cryptographic transformation of data that, when properly implemented, provides a mechanism for verifying origin authentication, data integrity and signatory non-repudiation |
| computer-interpretable format used for storing, accessing, transferring, and archiving data |
|
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.
|
| Facts, concepts, or instructions |
|
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.
|
| independent of a specific computer system |
| The manner in which information is displayed for use by a human. |
| Product Definition Data, Technical Data, Item, Feature, Drawing, Item. IdentificationIncludes materials, parts, components, subassemblies, assemblies, and equipment. The term product shall also encompass a family of products. |
| A representation of information about a product in a formal manner suitable for communication, interpretation, or processing by human beings or by computers. |
|
information about a product
Note 1 to entry: Note to entry: In ISO 10303, it is common to describe product information with respect to a specific industrial domain. |
| 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) |
| SMRL | STEP modules and resource library |
 |
| collection of application modules, business object models, and integrated resources intended to support one or more application protocols |
