(1) Digital Preservation

What a digital preservation system should do:• respect technical and human requirements from

institutional intrinsic and extrinsic views• archive the data with additional and sufficient

information (metadata) • save the data on three layers:

DURAble ARchitectural Knowledge – DURAARKfunded by the European Union within the 7th Framework

ProgrammeFebruary 2013 – January 2016

Goal & Scope:• develop methods and tools for sustainable long-term

preservation of building data (3D formats, metadata, related knowledge and Web data)

• analysis of potential stakeholders (architects, building owners, researcher, cultural heritage institutions etc.)

• address all layers of digital preservation (bit, logical, semantic)

• interlinked curation and preservation workflow• establish a competence center for archiving of 3D data at

the TIB in Hannover• NOT: develop a new digital preservation system

How does it look?• real representation of the archived object• metadata about it should be captured as well• plan and scan are associated over the real world representation

Scan

Plan

Point Cloud Scan• special 3D scanner analyzes real world objects and are able to

construct a digital 3D model – a point cloud• represents the constitution of an “is-built”-building• could differ from the plan but requires an existing building

Building Information Model• with the help of software (“CAD-System”) constructed model of a

building• geometric visualization of a building• it must not fit into the real building• enriched with (semantic) information from different sources (e.

g., vendor databases)• usage through different actors (e. g., architects, building

engineers etc.)

State of the Art (on preservation of architectural 3D data):

• various, established formats, but no standards• nearly no suitable metadata format• missing compatibility of existing preservation tools• few experiences / projects• not any experiences on the preservation planning

10 / 15 09 / 17 / 14

First results• recommendations for open,

standardized and archival formats:

– IFC-SPF (BIM)– E57 (point cloud)

• metadata schema “buildm” for content related description of the archived objects

• first prototype of a DURAARK workbench with following functionalities:

– semantic enrichment of 3D data

– identification of 3D formats– preperation for preservation

(2) The DURAARK project...

Next steps• establishment of the

recommended formats• stakeholder survey for

acceptance of our project(-results)

• digital preservation of 3D data in our digital preservation system

What we are doing with Rosetta:• we preserve digital materials on all three layers of

preservation• for our library, we have established and are establishing

standards and workflows towards the goal of digital preservation

• we enrich our digital material with metadata of our library catalogue

• and we are able to deal with a large amount of data.

Existing tools for various file formats:

Jhove, Tika, fido, fits, DROID, …

Few existing tools for Building Information Models (IFC-SPF) and point clouds (E57):

DROID signature pattern extension, E57 validator, IFC validator, …

Conclusion

Digital Preservation of architectural 3D data – an outlook:

• DURAARK workbench to aid producers in the preparation of objects for the delivery to a digital preservation system

• file format identification, technical metadata extraction, file format validation for IFC-SPF and E57 within Rosetta

• sample preservation planning for content types BIM & 3D scan

• curational tools to aid archives and libraries in appraisal and selection processes outside of the digital preservation system
