3.1.1

administered item

registered item for which administrative information is recorded

[SOURCE: ISO/IEC 11179‑3:2013, 3.2.2]

3.1.2

administrative information

<metadata registry> information about the administration of an item in a metadata registry

[SOURCE: ISO/IEC 11179‑3:2013, 3.2.3]

3.1.3

class

category or division of things 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 of the spatio-temporal paradigm used to define individuals in this International Standard, all classes are non-well-founded sets. These are explained in ISO 15926‑2.

[SOURCE: ISO 15926‑1:2004, 3.1.1]

3.1.4

commodity product class

product class that has sufficient characterization to indicate suitability for a defined use, and that is an open agreed standard

Note 1 to entry: Often a commodity product class is defined by several other standards. A piping component typically conforms to a “shape standard” and a “material standard”.

Note 2 to entry: Different manufactured product classes, which are specializations of the same commodity product class, are interchangeable for the use defined by the commodity product class.

3.1.5

core class

class that is a commonly used subdivision corresponding to terms used in common language

Note 1 to entry: The conditions for membership are often not formally defined; understanding of the class may be conveyed by example.

[SOURCE: ISO 15926‑1:2004, 3.1.4]

3.1.6

data

representation of information in a formal manner suitable for communication, interpretation, or processing by human beings or computers

[SOURCE: ISO 10303‑1:1994, 3.2.14]

3.1.7

de facto class

class corresponding to common natures that are widely recognized but not formally agreed or defined

Note 1 to entry: De facto classes may be formalized by international, national, or industry agreement.

[SOURCE: ISO 15926‑1:2004, 3.1.8]

3.1.8

information

facts, concepts, or instructions

[SOURCE: ISO 10303‑1:1994, 3.2.20]

3.1.9

ISO 15926 conforming reference data library

ISO 15926 reference data library that conforms to the requirements of ISO/TS 15926‑6

Note 1 to entry: An ISO 15926 reference data library can, but need not, conform to the requirements of ISO/TS 15926‑6.

Note 2 to entry: An ISO 15926 reference data library can, but need not, be a standard.

3.1.10

ISO 15926 reference data library

reference data library that is recorded as instances of entities in ISO 15926‑2

3.1.11

manufactured product class

class whose members are individuals produced by a manufacturing process

Note 1 to entry: The members of a manufactured product class may be discrete or may be batches or continuous flows, such as process fluids.

Note 2 to entry: A manufactured product class may correspond to a specification that has not been realized, such a product specification for which no products have been made.

[SOURCE: ISO 15926‑1:2004, 3.1.14]

3.1.12

physical quantity

property

aspect or quality of something that can be determined by measurement

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

3.1.13

possible individual

thing that exists in space and time

Note 1 to entry: This definition is adapted from ISO 15926‑2, within which “possible individual” is an entity, but not a defined term.

3.1.14

proprietary class

class whose specification for membership is owned, controlled, or protected by an organization and is not generally available outside that organization

[SOURCE: ISO 15926‑1:2004, 3.1.16]

3.1.15

proprietary product class

class that is a manufactured product class and a proprietary class

Note 1 to entry: Proprietary product classes are specializations that depend on rules of inclusion and exclusion, some of which are controlled in a closed way. This means that some aspects of the specification can be arbitrarily changed. Many proprietary product classes are specializations of commodity product classes, de facto classes, or both, where the additional restrictions reflect design or manufacturing details that the manufacturer uses to differentiate his product from others of the same general type.

3.1.16

reference data

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

[SOURCE: ISO 15926‑1:2004, 3.1.18]

3.1.17

reference data item

thing that is defined within a reference data library

Note 1 to entry: Each reference data item is an administered item.

3.1.18

reference data item definition by text

text, and optionally equations and figures, that is intended to be understood by a person, and that is the normative definition of a reference data item

3.1.19

reference data item definition by document reference

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

3.1.20

reference data item library record

reference data item and a set of statements about it within a reference data library

3.1.21

reference data item non-person-interpretable identifier

text that is a unique identifier for a reference data item and that is not intended to be interpreted by a person

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

3.1.22

reference data item person-interpretable identifier

text that is a unique identifier for a reference data item, and that is intended to be interpreted by a person

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

Note 2 to entry: If a reference data item is a class, then its reference data item person-interpretable identifier may be a term.

Note 3 to entry: The reference data item person-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 may be used in many contexts. Hence a reference data item person-interpretable identifier may be longer than a name in a natural language, and contain words which qualify a natural language name, to ensure that it is unique.

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

3.1.23

reference data library

managed collection of reference data

[SOURCE: ISO 15926‑1:2004, 3.1.19]

3.1.24

standard class

class whose specification for membership is owned or controlled by a standardization body and is publicly available

Note 1 to entry: Standard classes result from the work of national, international, or industry standardization bodies and cover sizes, shapes, materials, performance, and manufacturing processes of equipment and materials. The rules for exclusion and inclusion (or conformance) are agreed by an open, consensus process and are made publicly available. A standard class may only constrain one particular aspect and often be insufficient to determine usage or full manufacturing specifications.

[SOURCE: ISO 15926‑1:2004, 3.1.20]

3.1.25

statement

fact

information that is regarded as indivisible

Note 1 to entry: A statement can be recorded as an instance of the entity relationship in ISO 15926‑2. A set of one or more statements can be recorded in shorthand form as a single item as an instance of a template, as defined in ISO/TS 15926‑7.

3.1.26

thing

actual part of the real world, perceived part of the real world, or subject of thought

Note 1 to entry: A thing can be a material or non-material object, idea or action.

Note 2 to entry: This definition is adapted from ISO 15926‑2, within which “thing” is an entity, but not a defined term.

3.1.27

version of a reference data library

defined content from within a reference data library

Note 1 to entry: The content of a reference data library can change. A version of a reference data library cannot change.

Note 2 to entry: The formal definition of the class version of a reference data library in this part of ISO 15926 is “ multidimensional object that is a set of things and a set of statements about the set of things, where the things and the statements are within a reference data library”.
