ISO 18876 Integration of industrial data for exchange, access, and sharing

Glossary of terms

This glossary combines the terms and definitions from Parts 1 and 2 (fifth working drafts).

application model (AM)

model that represents information used for some particular purpose

NOTE   Some application models are also integration models.

class

collection to which some significance is attached

concept

general notion or abstract idea

construct

structure of data together with its intended meaning

data

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

[ISO 10303-1]

data model

definition, structure, and data types for data

derived concept

concept in an integration model that is wholly defined in terms of primitive concepts

foundation concept

primitive concept that determines the underlying world viewpoint of an integration model

EXAMPLE   The concepts of "class" and "individual" are foundation concepts for a general integration model.

general concept

primitive concept that has very wide applicability, but is a specialization of some foundation concept

NOTE   The boundary between a foundation concept and a general concept may be arbitrary; some concepts may be thought of as both foundation concepts and general concepts.

individual

thing that exists in space and time

NOTE   This includes things that actually exist, or have existed, and things that possibly exist in the past, present or future.

EXAMPLE   The pump with serial number ABC123, Battersea Power Station, Sir Joseph Whitworth, and the Starship "Enterprise" are examples of individuals.

information

facts, concepts, or instructions

[ISO 10303-1]

integration

activity that creates, modifies, or extends an integration model

integration model (IM)

application model that can represent the information that is represented by two or more application models

mapping

association of a set of elements of a model with a set of elements of another model

NOTE 1   A mapping can be uni-directional or bi-directional.

NOTE 2   A mapping is the result of apply a mapping specification to particular models.

mapping specification

definition of the transformations that relate elements of one model with elements of another model

NOTE 1   A mapping specification can include data structure transformations, data value transformations, data encoding transformations, and terminology transformations.

NOTE 2   Mapping specifications can be procedural, or declarative, or a combination of these.

model

limited representation of something suitable for some purpose

NOTE   A model can be data, or a data model, or a combination of these. See Annex D of ISO 18876-2 for further discussion of the relationship between models, data, and data models.

model context

range of activities and viewpoints for which an application model is valid

NOTE   This term is more general than application context as defined in ISO 10303-1.

model scope

range of information that an application model can describe

primitive concept

concept in an integration model that is not wholly defined in terms of other concepts

specific concept

primitive concept that is a specialization of some general concept and has a limited range of applicability

EXAMPLE   Car, process plant, quark, purchase order, and XML document are examples of specific concepts.

NOTE   The boundary between a specific concept and a general concept may be arbitrary; some concepts may be thought of as both specific concepts and general concepts.
