Introduction
ISO 10303 is an International Standard for the computer-interpretable representation and ex-
Change of product data. The objective is to provide a neutral mechanism capable of describing
product data throughout the life cycle of a product independent from any particular System.
The nature of this description makes it suitable not only for neutral file exchange, but also as a
basis for implementing and sharing product databases and archiving.
This International Standard is organized as a series of Parts, each published separately. The
Parts of ISO 10303 fall into one of the following series: description methods, integrated resources,
application protocols, abstract test suites, implementation methods, and conformance testing.
The series are described in ISO 103034. This part of ISO 10303 is a member of the integrated
resources series. Major subdivisions of this International Standard are:
- generic product description resources;
- generic management resources;
-
support resources.
The groupings of resource Schemas into these major subdivisions are shown in figure 1.
The generic product description resources provide an Overall organization for the integrated
resources that are documented in other Parts of ISO 10303. They support the description of
application-independent facts that are common to all products. In this part the combination
of the generic product description resources and the ISO 10303 integrated resources that are
defined in the other Parts that belong to the integrated resources class is referred to as the
“integrated product description resources” .
The generic management resources support the description of information that is used to man-
age and control product data. Together, the integrated product description resources and the
generic management resources are the foundations upon which application interpreted models,
the normative conceptual Schemas of application protocols, are built. Application interpreted
models apply selected generic management resources to elements of the integrated product de-
scription resources to satisfy the requirements that are specified in the appropriate application
reference model.
The support resources are a set of sh ared resour ‘ce cons tructs that
are used by the ISO 10303
integrated resources. They provi de an underlying consist ency across the resources of ISO
10303.

Section 2 : Generic product description resources
2.1 Introduction
This section specifies the ISO 10303 integrated resources used for the high-level description of a
product. The following Schemas are included:
-
application-contextschema;
- product-definition-Schema;
-
product erty-definitionschema;
-ProP
-
product-propertyrepresentation-Schema.
The application-tontext-Schema supports the description of the applicable usage of product
data.
The product-definitionschema supports the description of the identification of products,
the categorization of products, and the relationships among the definitions of products.
The product-property-definition-Schema supports the description of the characteristics of
a product.
The product-propertyrepresentationschema describes the structure for representing the
shape characteristics of a product.
NOTE 1 - This part is not limited to the domain of a specific application context. The reader
should not be misled by the deliberately limited scope of the examples.
NOTE 2 - The way in which the support resources are associated with the generic product descrip-
tion resources is described in annex E.

2.2.1 Introduction
This clause defines requirements for the application-tontext-Schema. This Schema defines
a mechanism for application protocols to define a frame of reference or context that applies to
particular sets of product data. An Overall application context has several context elements.
Esch context element may be referenced by a different aspect of product data.
A means is provided for users of product data to identify the application interpreted model in
terms of which that product data is defined.
2.2.2 Fundamental concepts and assumptions
The meaningful exchange of product data requires the identification of the application context
in which that product data is defined. One element of an application context is the application
interpreted model which is used. Esch application interpreted model belongs to one, and only
one, application protocol. Since all application interpreted models in ISO 10303 have unique
names, identification of an application interpreted model Schema name also uniquely identifies
an application protocol. Applications which use product data require information that identifies
the application interpreted model that defines the content and logical structure of the product
data.
2.2.3 application-contextschema entity definitions
2.2.3.1 application-context
An application-context is a context in which product data is defined. An application--
context represents various types of information which relate to product data and may affect
the meaning and usage of that data.
