GB/T 42534.1-2023 Fluid power- Specification of reference dictionary - Part 1 : General overview on organization and structure
1 Scope
This document provides a reference dictionary (hereafter referred to as dictionary) of fluid power as well as the contents and form of electronic data.
This document, based on ISO 13584-42 and ISO/IEC Guide 77-2, specifies a reference dictionary of standardized product properties for the area of fluid power.
Note: The properties are determined on the basis of standardized attributes, which are classified into definition classes, forming a so-called standardized “reference hierarchy”.
2 Normative references

4 Principles of specification
4.1 Set of attributes for description of a property
Properties shall be described by attributes as given in Table 1.
Note: The table contents are in accordance with the data model specified in ISO 13584-42, expanded where required as per ISO/IEC Guide 77-2.
4.2 Set of attributes for description of a class
Classes shall be described by attributes as given in Table 2.
Note: The table contents are in accordance with the data model specified in ISO 13584-42, expanded where required in accordance with ISO/IEC Guide 77-2.
4.3 Basic structure of reference dictionary
4.3.1 General
Each property requires a defined context. In accordance with the data model, this context is provided by allocation of each property to an associated definition class.
The definition class is one of the mandatory attributes of a property.
When strictly applying the rules of the data model specified in ISO 13584-42, it is impossible to end up with object classes that describe objects in all detail. Therefore, a clear distinction shall be drawn between definition classes and application classes. The properties defined within the definition classes of the property dictionary can, i.e. in the sense of their defined context, be used in any application class.
Within the hierarchic structure of definition classes and within the hierarchic structure of application classes, the rules of heredity, in accordance with the data model of ISO 13584-42, apply.
4.3.2 Basic structure of the hierarchic order of the definition classes
The basic structure of the hierarchic order of definition classes of this document is adapted from the ICS (International Classification of Standards).
To achieve compatibility with the data model of ISO 13584-42, ICS classes are given a verbal definition and are related to each other by introduction of appropriate classifying properties. The ICS structure is modified to eliminate classes such as "miscellaneous".
On the top level order of the ICS, besides generalities/terminology/standardization (ICS 01), we have the sciences and the industry sectors. Properties shall always be allocated to the most general possible class (here, ICS class), that is, if a property cannot be allocated to ICS 01 and its subclasses, consideration shall be given to its allocation to the relevant science class, and only if this is not possible shall it be allocated to the relevant industry sector class.
