This document specifies requirements for data dictionaries that are used by product catalogues for building services to provide the semantics of their definitions and data modelling. For this purpose, it defines an overall model that contains:
-
subject kinds that allow to distinguish:
-
product subjects representing products in product catalogues;
-
catalogue subjects comprising meta data of product catalogues;
-
various kinds of blocks that collect properties of complex product features, including ports and in/outlets;
-
-
relationship types that allow to distinguish between different kinds of relationships like isSubtypeOf, hasPart, or hasBlock;
-
property kinds to distinguish between:
-
static properties describing products by providing property values in product catalogues;
-
dynamic properties that describe the behaviour of products;
-
external properties that represent external conditions that influence the behaviour of the product by influencing the values of dynamic properties.
-
This document also describes a mapping of the overall model to the data dictionary model of ISO 12006‑3 by introducing a dictionary meta level.
Finally, to overcome deficiencies of the standards underlying ISO 16757‑5 in capturing all aspects of product catalogues, this document provides some rules and recommendations for required data dictionary elements.
This document does not describe how product catalogues have to be organized, and it does not describe any formats for the exchange of product catalogues. Product catalogues are described in ISO 16757‑5.
