DURAARK is an interdisciplinary EU FP7 project which researches and develops processes and methods for the digital preservation of architectural three dimensional data. Challenges addressed within the project relate to different aspects of the curation and preservation process, including semantic and geometric enrichment, consistent naming schemas and ontologies, as well as pre-ingest tasks in OAIS compliant digital preservation workflows. In a first step, the project identified stakeholders for methods and processes. Since the project strives for a holistic digital preservation approach, different models were taken into account to align the identified stakeholders with the overall curation and preservation workflow. This alignment leads to a better understanding of stakeholder involvement in the process and of the implications this involvement has on preservation decisions. It furthermore outlines the basis for future work in this area.
