Preserving the Long-Term Usability of Digital Building Documents through a Representation Information Repository


Core Concepts
Ensuring the long-term usability and preservation of digital building documents through the design of a representation information repository that captures the necessary context and metadata to maintain the meaning and significant properties of the digital content.
Abstract
The paper discusses the challenges of ensuring the long-term usability of digital building documents, especially in the context of the construction sector and public administration. It highlights the rapid obsolescence of formats, the lack of standardization, and the increasing distribution of related storage and processing systems as key issues. The authors introduce the concept of representation information (RI) from the OAIS reference model as crucial for giving meaning to the stored bit sequences. They then design a repository for RI and introduce 23 BIMcore content elements to capture structural, semantic, and contextual information about building-related digital formats and content. The proposed RI repository is intended to address several use cases, including data/document producers, construction experts as consumers, archive managers, computer experts, and technical historians. The BIMcore elements cover format identification, syntax and semantics, software tools, and building-specific context information, as well as the concept of significant properties that must be maintained over time. The authors illustrate the application of the RI repository in the context of BIM (Building Information Modeling), using the example of the IFC (Industry Foundation Classes) format and its customization for specific purposes. They explain how the repository can be used to implement the OAIS concepts of representation information, context information, and significant properties to ensure the long-term usability of digital building documents.
Stats
Digital building documents have a long lifecycle, often spanning the entire lifespan of a building or even indefinitely. The construction sector faces challenges such as rapid format obsolescence, lack of standardization, and increasing distribution of storage and processing systems. Building Information Modeling (BIM) introduces additional challenges with highly specialized formats and large volumes of data. The proposed RI repository aims to capture 23 BIMcore content elements to describe the structural, semantic, and contextual information of building-related digital formats and content.
