Before reading these implementation guidelines, it is highly recommended to read the “Description of Parts” section in the VEC Online Model Description. This section explains the concepts for the representation of part master data and component specifications in the VEC.

The definition of the product itself (the wiring harness) is one of the major use cases of the VEC. The figure below illustrates the basic building blocks in the data model and provides guidance on where to look for specific topics.

Part Master Definition Accessories Part A being an accessory for Part B means, that if Part B is used somewhere in a harness, then Part A might (or must) be used as well.

A wide range of different systems, supporting different use cases, are used in the process of wiring harness development. All of them might have a VEC-Interface for input & output, so sooner or later the question arises “What are the expectations for the behavior of those interfaces?

The VEC has two major key concepts: PartVersion and DocumentVersion. Both are ItemVersions and both are used to reference / identify a piece of relevant information in a PDM context unambigiously.

Description of Parts In other formats like the KBL- or the KOMP-model the diverse types of parts (e.g. connector housing, terminal, wire) are differentiated by inheritance with a subclass for each type inheriting from the type corresponding to PartVersion.

General Technical Part The class GeneralTechnicalPartSpecification is intended to aggregate common technical attributes that are relevant for most kinds of parts (e.g. massInformation or information about valid temperature environments). With the composition of PartRelations other PartVersions can be defined as accessory parts.
