The long-term usability of digital building documents is essential for the maintenance and optimization of infrastructure portfolios. It supports the preservation of building-specific knowledge and the cultural heritage hidden within. However, having to do this throughout the lifecycle of a building - or even indefinitely - remains a major challenge. This is especially true for organizations responsible for large collections of digital building documents, such as public administrations or archives. In this article, we first describe the challenges and requirements associated with preservation tasks, and then introduce the concept of so-called representation information within BIM (Building Information Modeling). This type of information is important to give meaning to the stored bit sequences for a particular community. Then, we design a repository for representation information and introduce some so-called 23 BIMcore content elements. Finally, we focus on BIM and the construction sector and explain how the proposed repository can be used to implement the two concepts introduced in the ISO reference model OAIS (Open Archival Information System), namely the representation information and the context information, as well as the concept of significant properties, which has not yet been explicitly modeled in OAIS.

翻译：建筑数字文档的长期可用性对于基础设施资产组合的维护与优化至关重要，有助于保存建筑专属知识及其中蕴含的文化遗产。然而，在建筑全生命周期（甚至无限期）内实现这一目标仍是重大挑战，尤其对于承担大量建筑数字文档管理职责的公共管理部门或档案馆等机构。本文首先阐述保存任务面临的挑战与需求，进而引入建筑信息模型（BIM）中所谓的"表征信息"概念——这类信息对于特定群体理解存储比特序列的语义意义至关重要。随后，我们设计了一个表征信息资源库，并介绍若干称为"23个BIMcore内容要素"的组成元素。最后，聚焦BIM与建筑行业，论述该资源库如何实现ISO参考模型OAIS（开放档案信息系统）中引入的两项核心概念（表征信息与上下文信息），以及OAIS尚未显式建模的"显著性特征"概念。
