The scope of conformance testing of a specific implementation is the requirements specified for the conformance classes claimed for the implementation in the protocol implementation conformance statement (PICS). The tests are selected from the ATS, based on the conformance class claimed by the implementation. Test results provide the basis for conformance assessment.
ISO 10303 contains ATSs and defines ATMs for performing conformance testing to provide a basis for test results that are repeatable, comparable, and auditable. Inclusion of conformance testing procedures in ISO 10303 is intended to promote widespread acceptance of test results.
5 Architecture of ISO 10303
5.1 Concepts behind the architecture
The ISO 10303 architecture is designed to support the development of standards for product data exchange and product data sharing. The architecture is constrained by the following concepts:
— the scope of what is standardized and what is conformance tested is set at the level ofan application;
— Information requirements are based on a model of a business activity;
— information requirements are standardized using natural language; and
— a mapping is specified that defines the data structures and population constraints using the IRs that satisfy the information requirements.
ISO 10303 is implemented through APs. An AP consists of the following major elements:
— an AAM describing the business process that the information model supports;
— an ARM specifying the information requirements;
— an information model based on the IRs, called an application interpreted model (AIM), that is a basis for implementations of ISO 10303;
— zero or more information models for data structures based on the ARM, called a business object model (BO Model), that is a basis for implementations of 150 10303.
The architecture is based on standardizing industry information requirements and mapping those information requirements to an information model based on the IRs. The process of mapping information requirements to the IRs is known as “interpretation”.
The ISO 10303 architecture focuses on the information required by industrial processes rather than on the processes themselves, as the processes can change over time, while the underlying information requirements are longer lasting. This focus on information allows ISO 10303 to support data exchange, some forms of data sharing, as well as long-term data retention.
Whenever a resource construct is used to represent the same information requirement in different APs, the same interpretation of that resource construct shall be used.
5.2 Elaborations of the architecture
5.2.1 General
The general architectural principles described in 11 have been elaborated into two architectures: the “initial architecture” and the “modular architecture”. Both architectures adhere to the fundamental principles described in 4. The primary change introduced by the modular architecture is the explicit harmonization of common information requirements.
NOTE The term “ISO 10303 architecture”, without qualification, refers to the general principles described in Li. and the common aspects of Its elaborations.ISO 10303-1 pdf download.
