Digital preservation: past efforts

Building and construction• PROBADO [DFG 2007-2011]

• Music and 3D geometry• No BIM models• OAIS compliant

• FACADE [US 2006-2009]• Proprietary CAD models of buildings• No BIM Models• Identifies BIM as next necessary step

Other engineering domains• LOTAR

• Remove dependence from proprietary software formats

• Aerospace and defense• STEP • OAIS

• SHAMAN [EU-funded 2007-2011]• Various engineering domains• PLM-centric independent of format

• VDA 2958• Long-term archiving of STEP domain-based

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

Goals and Challenges (1/2)

Goal Methods and tools for sustainable long-

term preservation of building data (3D and BIM models, metadata, related knowledge & Web data)

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
