Towards Support for Long-Term Digital Preservation in Product Life Cycle Management

Important legal and economic motivations exist for the design and engineering industry to address and integrate digital long-term preservation into product life cycle management (PLM). Investigations revealed that it is not sufficient to archive only the product design data which is created in early PLM phases, but preservation is needed for data that is produced during the entire product lifecycle including early and late phases. Data that is relevant for preservation consists of requirements analysis documents, design rationale, data that reflects experiences during product operation and also metadata like social collaboration context. In addition, also the engineering environment itself that contains specific versions of all tools and services is a candidate for preservation. This paper takes a closer look at engineering preservation use case scenarios as well as PLM characteristics and workflows that are relevant for long-term preservation. Resulting requirements for a long-term preservation system lead to an OAIS (Open Archival Information System) based system architecture and a proposed preservation service interface that respects the needs of the engineering industry

Towards a Curation and Preservation Architecture for CAD Engineering Models

For many decades, computer-aided design (CAD) packages have played an important part in the design of product models within the engineering domain. Within the last ten years, however, the increasing complexity of CAD models and their tighter integration into the workflow of engineering enterprises has led to their becoming the definitive expression of a design. At the same time, a paradigm shift has been emerging whereby manufacturers and construction companies enter into contracts to take responsibility for the whole lifecycle of their products – in effect, to sell their product as a service rather than as an artefact. This makes necessary not only the preservation of the product’s design, but also its continuing intelligibility, adaptability and reusability throughout the product’s lifecycle. The CAD models themselves, though, are typically in close
