Endangered large

3D digital engineering models produced as part of building or engineering design processes. The production of such drawings has progressed from a digital analogue of paper to complex digital environments such as BIM (Building Information Modelling) which combine original drawings, libraries of compound objects, and links to external data sets such as about the performance of materials and maintenance of parts.

Group: Engineering

Trend: No change

Consensus Decision

Added to List: 2017

Last update: 2018

Previous category: Of Concern

Imminence of Action

Action is recommended within three years, detailed assessment within twelve months

Significance of Loss

The loss of tools, data or services within this group would impact on many people and sectors.

Effort to Preserve

It would require a major effort to address losses in this group, possibly requiring the development of new preservation tools or techniques.

Examples

Building Information Management, Computer Aided Design, Product Data Management in engineering and architecture,

‘Critically Endangered’ in the Presence of Aggravating Conditions

Lack of preservation mandate or collecting institution; lack of preservation capability in data owner; irregularities in supply chains; complex or long data supply chains; dependencies on proprietary software or formats; lack of persistent identifiers; poorly managed IPR; temporary joint-venture companies; poor records management; poor regulatory compliance; encryption.

‘Vulnerable’ in the Presence of Good Practice

Well managed data infrastructure; preservation from the point creation; carefully managed IPR; persistent identifiers; well managed records management processes; recognition of preservation requirements at highest levels; strategic investment in digital preservation; host clearly identified; participation in digital preservation community.

2019 Review

This entry was first submitted in 2017 when the Jury lacked the capacity to consider it in detail. It has been assessed this time with additional expertise co-opted. Nonetheless it remains a very broad category including major one-off construction and engineering projects, a long tail of more minor building programmes, as well as large volume but homogenous production processes in engineering. The key consideration is that the lifecycle of the products and the data which describes them vastly exceeds the short lifecycles of the infrastructures on which they are designed. This challenge is compounded by supply chains that may involve many different stages of production, as well as the delivery of large projects through transitory joint ventures companies that have no residual mechanism or capacity to preserve the data thereafter.

Additional Jury Comments

Data in this category enables the safety and security of critical infrastructure, but the responsibility to maintain data is unclear, nor are retention periods clear. Although examples of good practice can be identified, the extent to which there are working solutions at large seems doubtful and it’s surprising that there are not more, and more diverse, success stories to report.
