As a part of the on-going DURAARK project, this review summarizes research on long term digital preservation (LDP) of 3D architectural data related to architecture, engineering, and construction, within the domain of libraries, museums, archives, and small and medium sized enterprises (SMEs). The paradigm shift from 2D to 3D modelling raised new challenges for long-term preservation of the architectural data. For example, the original 3D models and the actual state of built architectures might lose fidelity in the long run because of environmental influences and systematic changes. Likewise, the access mechanisms of current preservation systems in the architectural domain are based on simple metadata schemas inherited from the analogue world, for example searching with a card index. In the absence of standard process and LDP strategies for 3D architectural data, it would be difficult to store and retrieve the detailed semantic information from the archival systems in the long run. Considering the various challenges in capturing, preserving, retrieving, and securing the 3D architectural data, this literature review is an endeavour to synthesize the current research findings and highlights the areas that lack sufficient research with regard to long term preservation of 3D architectural data. The paper employs open archival information systems (OAIS) models, a de facto standard for the LDP, to analyse the shortlisted publications. Finally, the paper presents on-going efforts and goals of DURAARK, an EU funded project.
