3.1.17
application protocol
AP
part of ISO 10303 that specifies an application interpreted model satisfying the scope and information requirements for a specific application
Note I to entry: This definition differs from the definition used in 150 7492-2:1989 because the protocols address different Contexts of use.
3.1.18
application reference model
ARM
information model that describes the information requirements and constraints of an application within an application protocol or module
3.1.19
application resource
Integrated resource whose contents are related to a group of application contexts
3.1.20
assembly
product that is decomposable into a set of components or other assemblies from the perspective of a specific application
3.1.21
business object model BO Model
single integrated information model for the scope of an AP
3.1.22
common resources
collection of information models, specified in the EXPRESS language, that can be reused to specify appllcation.speciflc Information models within the domain of industrial data
Note I to entry: The resource constructs defined by an application module are those defined In Its module interpreted model schema.
Note 2 to entry: The terni does not specify a specific series of ISO 10303 parts.
3.1.23
component
product that is not suhfrct to decomposition from the perspective of a specific application
3.1.24
conformance assessment
analysis of conformance testing results to determine conformance to a particular application protocol’s conformance class or option
3.1.25
conformance class
subset of an application protocol for which conformance can be claimed
3.1.26
conformance option requirement
Incremental subset of an application protocol for which conformance can be claimed In addition to the conformance claimed for one or more conformance classes
3.1.27
conformance
precise, text definition of a characteristic required to be present in a conforming implementation
The IRs in Iso 10303 are divided into two groups: generic resources and application resources. The generic resources are independent of applications and may reference other resources. The application resources may reference other resources and may add other resource constructs for use by a group of similar applications. The IRs may reference product data descriptions written using EXPRESS from other International Standards.
4.3.3 Support for applications
The IRs define a generic information model for product information. They are not sufficient to support the information requirements of an application without the addition of application specific constraints, relationships, and attributes.
ISO 10303 defines APs In which the IRs are interpreted to meet the product information requirements of specific applications. The interpretation is achieved by selecting appropriate resource constructs and refining their meaning, by specifying any appropriate constraints, relationships, and attributes. This interpretation results in an application interpreted model (AIM). The AIM is documented as part of an AP.
ISO 10303 has two mechanisms to ensure consistent interpretation when a resource construct represents the same information requirement in different APs. One mechanism uses interpreted resource constructs appearing in more than one AP as a documented application interpreted construct (AIC). The other mechanism uses application modules (AMs that document the harmonized requirements along with the interpreted resource constructs.
NOTE Subclauscs 6.4 and £5 discuss application interpreted constructs and application modules in more detail.
The scope and information requirements of the application are specified using the terminology of the application domain. The Al’ provides a mapping to show how the interpretation of the IRs is used to meet the information reqLlirements of the application domain.
ISO 10303 provides business object models that present complex models In a form that may he more understandable to application experts.
4.3.4 Implementation methods
Each implementation method included in ISO 10303 is specilied by a mapping from the EXPRESS language onto the formal language used for the method. The mapping is independent of the AI The mapping is expressed in a formal notation. At least three implementation methods for ISO 10303 have been identified (see 6.3.4).
4.3.5 Implementations
An Al’ may specify one or more applicable implementation methods from the set of impLementation methods in ISO 10303. An Implementation shall apply one or more of the Implementation methods specified in the Al’ to the AIM.
4.3.6 Conformance testing
Conformance of an implementation to an AP is specified by the conformance requirements in the AP.
A set of tests, specified in an abstract test suite (ATS). may be defined for each AP. When associated with an abstract test method (ATM), these tests can be used to assess the conformance ofan implementation. The overall framework for conformance assessment is specified in ISO 10303-31.
