information (3.1.5) about the administration of an item in a reference data library (3.1.17)

[SOURCE:ISO/IEC 11179-3:2023, 3.2.67, modified — The domain has been removed and"registry" has been replaced by"reference data library".]

3.1.2

attribute

data (3.1.4) element for the computer-sensible description of a property (3.1.10) , a relation or a class (3.1.3)

3.1.3

class

category or division of things (3.1.22) based on one or more criteria for inclusion and exclusion

Note 1 to entry: A class need not have any members (things that satisfy its criteria for membership).

Note 2 to entry: Because a spatio-temporal paradigm is used to define individuals in this document, all classes are non-well-founded sets. These are explained in ISO 15926-2:2003, D.2.4.

3.1.7

maintenance organization

organizational unit that is responsible for the maintenance of the reference data library (3.1.17)

Note 1 to entry: Procedure for the maintenance of ISO/TC 184/SC 4 reference data (3.1.11) is described in ISO/TC 184/SC4 N2591^[12].

Note 2 to entry: The maintenance organization in this document represents the combination of the ISO/TC 184/SC 4 secretariat, the ISO/TC 184/SC 4/WG 3 and the ISO/TC 184/SC 4/WG 22 together carrying out the task of maintenance of ISO/TS 15926-4 reference data library published as a database using the procedure. The maintenance team (MT) is defined by the ISO/TC 184/SC 4/WG 3 and the validation team (VT) is defined by the ISO/TC 184/SC 4/WG 22.

3.1.8

possible individual

thing (3.1.22) that exists in space and time

Note 1 to entry: This definition is taken from ISO 15926-2, in which “possible_individual” is an entity but not a defined term.

3.1.9

power class

set of all subclasses (3.1.21) of a class (3.1.3) , including the class itself and the empty set

Note 1 to entry: A subclass of a power class selects subclasses that satisfy a specific context. A restricted set of subclasses can be a “facet” or “aspect”.

3.1.10

property

aspect or quality of something that can be determined by measurement or observation

Note 1 to entry: The term “property” is used in ISO 15926-2.

3.1.11

reference data

process plant life-cycle data (3.1.4) that represents information (3.1.5) about classes (3.1.3) or individuals which are common to many process plants or of interest to many users

[SOURCE:ISO 15926-1:2004, 3.1.18]

3.1.12

reference data item

thing (3.1.22) that is defined within a reference data library (3.1.17)

3.1.13

reference data item definition by text

text, and optionally equations and figures that are intended to be understood by a human, and that is the normative definition of a reference data item (3.1.12)

3.1.14

reference data item definition by document reference

normative reference to a document that provides the normative definition of a reference data item (3.1.12)

3.1.15

reference data item non-human-interpretable identifier

text that is a unique identifier for a reference data item (3.1.12) and that is not intended to be interpreted by a human

Note 1 to entry: The use of a reference data item non-human-interpretable identifier is defined in 5.2.

3.1.16

reference data item human-interpretable identifier

text that is a unique identifier for a reference data item (3.1.12) and that is intended to be interpreted by a human

Note 1 to entry: The use of a reference data item human-interpretable identifier is defined in 5.3.

Note 2 to entry: If a reference data item is a class (3.1.3) , then its reference data item human-interpretable identifier can be a term.

Note 3 to entry: The reference data item human-interpretable identifier is used for all references to a reference data item in natural language text definitions.

Note 4 to entry: Names in natural language and terms in dictionaries are often unique only within a context. A reference data item can be used in many contexts. Hence, a reference data item human-interpretable identifier can be longer than a name in a natural language and contain words that qualify a natural language name to ensure that it is unique.

Note 5 to entry: A reference data library (3.1.17) can contain additional terms for a reference data item which are not unique and which are used within particular contexts.

3.1.17

reference data library

RDI

managed collection of reference data (3.1.11)

[SOURCE:ISO 15926-1:2004, 3.1.19]

3.1.18

reference data library module

collection of reference data items (3.1.12) within a reference data library (3.1.17) that shares the same subject area

[SOURCE:ISO/TS 15926-4:2024, 3.1.14]

3.1.19

relationship

connection among model elements

Note 1 to entry: In this document, a relationship is one of: an association, a generalization or a specialization.

[SOURCE:ISO/IEC 11179-3:2023, 3.1.4, modified — The domain has been deleted.]

3.1.20

superclass

class (3.1.3) that is a generalization of one or more other classes

Note 1 to entry: The classes being generalized are known as subclasses (3.1.21) .

Note 2 to entry: A particular class can be a superclass with respect to one relationship (3.1.19) and simultaneously a subclass with respect to another relationship.

[SOURCE:ISO/IEC 11179-3:2023, 3.1.9, modified — The domain and note 2 to entry have been deleted.]

3.1.21

subclass

class (3.1.3) that is a specialization of another class

Note 1 to entry: The class being specialized is known as a superclass (3.1.20) .

Note 2 to entry: A particular class can be a subclass with respect to one relationship (3.1.19) and simultaneously a superclass with respect to another relationship.

[SOURCE:ISO/IEC 11179-3:2023, 3.1.10, modified — The domain and note 2 to entry have been deleted.]

3.1.22

thing

anything that is, or can be thought about, or perceived

Note 1 to entry: This definition is taken from ISO 15926-2, in which thing is an entity but not a defined term, including material and non-material objects, ideas, and actions.
