Digital architecture archives (Henk Vanstappen and Wim Lowet)

The memory of the architect. Creation and preservation of born digital architectural archives

CVAs : center of expertise coordinating the archiving of private documents for the architectural heritage in Flanders. DATABLE : consultancy in sustainable digital collection management.

Completed research steps : - survey : how are digital architectural archival records created and managed - case study : what steps are necessary at ingest and preservation - one more thing

1. Born-digital architectural archives Softwares being used ... drawing and design (sketchup and autocad mainly) + presentation and visualisation (Adobe mainly) - 2D + 3D geometry (vector based) - Intelligence (layers, text, look and feel, behaviour, complexity grow in each version)

2. preservation issues i. seldom open technologies problems with automatic file format identification and validation few alternatives = greater risk for obsolescence (mac vs windows for proprietary software, some aren't cross platforms)

ii.often problems with backward compatibility some files versions are too old to be opened by recent versions of the softwares

iii.technology is complex each program has its own underlying method to define geometrical forms

3. policies for preservation - migration vs emulation - importance of knowledge about the collection - importance of central storage - importance of making choices

threats → OS migration → employees leave firm (expertise) → failure in software company → raise in license costs

stakeholders → colleagues → legal department → PR-department → clients → fanbase → future generations

Use cases can be varied( post construction management, website publishing, book publishing, exhibitions...)

Is editing necessary? Is look and feel important? Does text need to remain in the same font? How about layers?

2 major options → migration → emulation/software preservation

Migration to open format → file format specs published → no licensing issues → software tools available → no significant information lost → reversible to original

Some tests have been done to STEP lots of layers vanished same with VMRL

Emulation what do you want to emulate? → document original software versions → archive original software → complex technology → licensing issues

knowledge about the collection Documentation of the working process. Understanding about design process is a prerequisite to make decisions about the preservation actions.

MDMA project clear naming convention and folder organisation http://www.projecttracks.be/en/projects/detail/digital-file-management-at-mdma

knowledge of collection (arrangement, design process) central storage knowledge of stakeholders, use cases, threats, options, costs and gains

3D doesn't just apply to architecture Film preservation, sculpture etc...
