As part of the eArchiving Initiative, PRISMA has prepared a report, authored by Nicola Amico and Achille Felicetti, titled "3D Data Long-Term Preservation in Cultural Heritage". The document outlines challenges and strategies for preserving 3D digital data in cultural heritage. It addresses technological obsolescence, sustainable storage, metadata management, and adherence to FAIR principles (Findability, Accessibility, Interoperability, and Reusability).
Key points include:
1. Technological obsolescence: ensures continuity through proper data migration, format updates, and compatible storage solutions.
2. Metadata importance: metadata (descriptive, structural, administrative, and preservation) is critical for data accessibility and longevity, including standards like PREMIS and OAIS.
3. Standards and interoperability: emphasises the need for consistent formats and practices, like CIDOC CRM, and the use of open, widely accepted file formats (e.g., OBJ, PLY, glTF).
4. Repositories and public engagement: highlights the role of certified repositories, collaboration platforms, and public accessibility in preservation.
5. Case study: The Agios Ioannis Lampadistis Monastery in Cyprus serves as an example of employing Heritage Building Information Modelling (HBIM) for integrating historical, architectural, and digital data to ensure preservation and accessibility.
The report advocates for a structured approach to data management to preserve 3D cultural heritage effectively for future generations. For further information, please download the report below.
