title: Current state of 3D object digital preservation and gap-analysis report
creators: Michelle Lindlar Hedda Saemann Sebastian Ochmann Östen Jonsson Ujwal Gadiraju
abstract: <p>The DURAARK project is developing methods and tools for the Long-Term Preservation (LTP) of architectural knowledge, including approaches to: enrich Building Information Models with &ldquo;as built&rdquo; information from scans, semantically enrich building models with additional data sets, preserve 3D models for future reuse.</p>
  
  <p>This deliverable identifies gaps in existing processes for the digital preservation of 3D objects. The gap analysis is approached through an in-depth analysis of two areas. One area is that of fundamental digital preservation tools and processes regardless of<br>
  their content type. It describes processes and standards adapted by the global digital preservation community and implemented in archives of varying domains, e.g., archives dealing predominantly with e-publications as well as AV-archives. The second area is<br>
  that of current existing processes for the digital preservation of 3D objects. It describes aspects and challenges which are uniquely tied to the long-term archiving process of this content-type and lists existing tools and standards. The gaps are identified through a<br>
  comparison of the content type agnostic and the 3D-specific state of the art descriptions.</p>
