ISO 13584-101:2003

Industrial automation systems and integration — Parts library — Part 101: Geometrical view exchange protocol by parametric program

ISO 13584-101:2003 specifies a particular representation category, called basic_geometry. This representation category captures the generic concept of the shape of a part. It may be associated with any of the items defined in a parts library. ISO 13584-101:2003 also defines how representations that belong to this representation category may be exchanged within a library exchange context by means of FORTRAN programs compliant with ISO 13584-31:1999, or, by case of separate agreement between the sender and the receiver, by means of any other parametric formats.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.

Introduction

ISO 13584 is an International Standard for the computer-interpretable representation and exchange of
parts library data. The objective is to provide a neutral mechanism capable of transferring parts library
data, independent of any application that is using a parts library data system. The nature of this
description makes it suitable not only for the exchange of files containing parts, but also as a basis for
implementing and sharing databases of parts library data.
ISO 13584 is organized as a series of parts, each published separately. The parts of ISO 13854 fall
into one of the following series: conceptual descriptions, logical resources, implementation resources,
description methodology, conformance testing, view exchange protocol, and standardized content.
The series are described in ISO 13584-1. This part of ISO 13584 is a member of the view exchange
protocol series.
A view exchange protocol specifies how a particular representation category of the items described in
a parts library may be exchanged in a library exchange context. It defines the identification of the
representation category, the means to be used to exchange representations that belong to this
representation category, the implementation resources that shall be available on any implementation
that claims conformance to this view exchange protocol, and the standard data that shall be
recognized by any implementation that claims conformance to this view exchange protocol.
This part of ISO 13584 specifies how geometric representations of the items described in a parts
library may be exchanged by means of parametric FORTRAN programs based on the application
programming interface specified in ISO 13584-31:1999, or, by case of separate agreement between
the sender and the receiver, by means of non-standardized parametric formats.

INTERNATIONAL STANDARD ISO 13584-101:2003(E)

Industrial automation systems and integration – Parts
library – Part 101: Geometrical view exchange protocol by
parametric program
1 Scope
This part of ISO 13584 specifies a representation category called basic_geometry. This representation
category captures the generic concepts of the shape of a part. This representation category may be
associated with any of the items defined in a parts library. This part of ISO 13584 also defines how
representations that belong to this representation category may be exchanged within a library
exchange context by means of FORTRAN programs compliant with ISO 13584-31:1999.
The following are within the scope of this part ISO 13584:
— the definition of the basic_geometry representation category and the mechanisms to be used to
reference it;
— the properties to be used to characterize a particular representation within the basic_geometry
representation category;
— the exchange format to be used for the library external files that describe the basic_geometry
representations of classes of items described in a parts library by means of FORTRAN
programs based on the application programming interface specified in ISO 13584-31:1999;
— the mechanism to be used, by case of separate agreement between the sender and the
receiver, to reference external files that describe the basic_geometry representations of classes
of items described in a parts library by means of formats not specified in ISO 13584;
— the implementation resources to be supported on any implementation that claims conformance
to this part of ISO 13584;
— the dictionary entries to be supported by any implementation that claims conformance to this
part of ISO 13584;
— the standard data to be recognized by any implementation that claims conformance to this part
of ISO 13584.
The following is outside the scope of this part of ISO 13584:
— the structure and exchange format of a library delivery file that includes references to the
representation category defined in this part of ISO 13584, and/or to the library external files
whose exchange format is specified.
NOTE 1 The structure of a library delivery file is defined by a library integrated information model
specified in one of the logical resource series parts of ISO 13584.

4 Identification of the basic_geometry representation
4.1 Concepts
When a library item is selected, it is often useful to access the shape of this item. Such a shape is a
generic concept that may be captured at various levels of completeness and detail. These levels may
be defined independently of the library items by the requirements that are intended to be met by each
level.
To address this requirement, this part of ISO 13584 defines:
— a particular representation category, called basic_geometry, that provides for the generic
concept of the shape of a library item;

1) To be published.
8 © ISO 2003 – All rights reserved

---------------------- Page: 14 ----------------------
ISO 13584-101:2003(E)
— five view control variables that are used to characterize the conceptual requirements that are
intended to be met by each shape associated with the same library item;
— an exchange format of the basic_geometry representation category intended to be referenced
from its library description and that consists of FORTRAN programs based on the
ISO 13584-31:1999 standard API;
— a generic exchange mechanism that may be used by case of separate agreement between the
sender and the receiver, and that provides the library description of this representation category
by means of non-standardized parametric formats.
4.2 Standardized dictionary entries
The information model of the basic_geometry representation category shall be defined by standard
data that consist of a functional view class entity data type instance. Such a functional view class is
captured by an instance of the functional_view_class entity data type.
NOTE 1 Functional view of a part is defined in ISO 13584-1. The functional_view_class EXPRESS
entity data type is defined in ISO 13584-24.
EXAMPLE The information model of the basic_geometry representation category might be defined in
EXPRESS through attributes like the geometry level, and a content that is an ISO 10303-43 representation.
Such a description might be as follows:
ENTITY basic_geometry;
level: geometry_level_type;
...
content: representation;
END_ENTITY;
Using the EXPRESS resource constructs defined in ISO 13584-24, the same information model may also be
defined and exchanged as an instance of a functional_view_class entity data type, as follows:
#1 = FUNCTIONAL_VIEW_CLASS(., 'basic_geometry', (#10, .), (#11));
#10 = PROPERTY_BSU('level',.);/* a view control variable */
#11 = PROPERTY_BSU('content',.); /* a view property */
The latter description is the one used by this part of ISO 13584, and the corresponding instances will be
found in the dictionary of a conforming implementation.
The universal identification of basic_geometry functional view class by means of a basic semantic unit
is defined in 4.2.1. The universal identification of the view control variables defined for this functional
view class, together with their domains of values are defined in 4.2.2. The functional_view_class
instance shall not contain any view_properties. The attribute its_superclass of this instance does
not exist, i.e., the corresponding functional vie
...
