Abstract
The representation of information and its exchange in a communication requires the use of a common information model to define the semantics and syntax of the representation and a common dictionary to define the meaning of the data items. These fundamental concepts are the basis of the new standard ISO 10303-235: 'Engineering properties for product design and verification' for the computer representation and exchange of material and any other engineering properties of a product and to provide an audit trail for the derivation of the property value. A related dictionary conforming to ISO 13584 can define testing methods and their properties and enable the information model to be used for any property of any product.
Highlights
Engineering properties are essential information for design and manufacturing processes and play an increasing role in the management of products throughout their life-cycle, including the end-of-life phase
The representation of information and its exchange in a communication requires the use of a common information model to define the semantics and syntax of the representation and a common dictionary to define the meaning of the data items
The fundamental requirement for the communication of information in a natural language is the combination of a common information model and a common dictionary
Summary
Engineering properties are essential information for design and manufacturing processes and play an increasing role in the management of products throughout their life-cycle, including the end-of-life phase For these reasons it is necessary to be able to communicate the information about the meaning of these properties and their values efficiently and without ambiguity among many different software programs and to retain this information for the lifetime of the product, independently from any proprietary software. The structure of the information model is defined by the grammatical rules for a sentence that are particular to the natural language The application of this model structure enables the recipient of a communication to correctly interpret the roles of the data items in the structure, and the dictionary can be used to extract the meaning of the information that the data stream represents. All the members in a communication chain must use the same information model and the same dictionary
