PartVersion

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.

Before reading these implementation guidelines, it is highly recommended to read the “Composite Part Descriptions” section and its subsections in the VEC Online Model Description first. Whereas the model description defines the general concepts of multilevel composite parts and 100% and 150% variance for those parts, this implementation guideline follows a use case oriented approach and explains the correct usage of the different aspects of a VEC implementation (e.

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.

For reasons of traceability (e.g. requirements) or because certain information is better represented in other standards than in the VEC format (e.g. 3D models for components), it is necessary to be able to reference external documents from VEC elements.

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.

Parts, Documents and Resources DocumentVersion, PartVersion and ResourceVersion are representing one of the most fundamental key concepts of the VEC. They are the only classes in the VEC model that are defining version information.
