The document outlines the Duraark project's goals and challenges in ensuring the long-term preservation of building information models (BIM) and related data. It highlights the necessity for sustainable methods to manage diverse files and stakeholders, addressing issues like semantic enrichment, interoperability, and digital decay. The project aims to facilitate better archiving practices and develop strategies to enhance the longevity and accessibility of architectural data.

6. Goal

Methods and tools for sustainable long-term
preservation of building data (3D and BIM
models, metadata, related knowledge & Web
data)
Challenges

Diverse stakeholders: architects, building
operators, urban planners, archivists, …

Diversity of data - interoperability: low-level
point clouds & legacy 3D models up to enriched
Building Information Models (BIM), higher-level
semantics and Web data / knowledge

Building, model and data evolution: document
temporal evolution, documentation of „as-build‟ in
addition to „as-planned‟ to prevent information
loss and enable repair

7. Challenges

“Semantic” enrichment of building
knowledge: exploiting Web data and
knowledge to enrich low-level building
data.

Inconsistent vocabularies: adopting
state of the art vocabularies and
schemas towards sustainability

Enrichment of point clouds:
Compartmentalize / cluster huge data
sets (1GB upwards per partial scan) by
semantic tagging.

Long-term readability / renderability
of architectural models: addressing
digital decay (eg due to deprecated
file formats) and model evolution
