Simple Explanation (ELI5)

Think of building a sandcastle: if you don’t note which sticks, shells, and sand you used, no one can rebuild it or understand your choices. IDOVIR is like a digital notebook that records all this, so anyone can learn from and improve your work.

Key Advantages & Current Limits

🟢 Pros: Standardizes documentation, making 3D models verifiable and reusable by anyone (researchers, students, museums). 🟢 Pros: Promotes interoperability with tools like GIS, BIM, and rendering engines (Unity/Unreal), enabling advanced analysis. 🔴 Cons: Requires time and expertise to annotate paradata correctly, especially for non-expert teams. 🔴 Cons: Reliability scoring depends on human judgment, which can vary between experts.

Future Outlook & Takeaways

In the next 3-5 years, IDOVIR could become the global standard for reconstruction documentation, integrated with VR and AI for interactive historical simulations. This will make past stories more immersive and accessible to schools and the public.

How can virtual reconstructions be documented to make them truly...

Virtual reconstructions of buildings and cities have become essential tools for scholars, architects, and museums. Showing a 3D model is impressive, but behind that result lies a series of choices, sources, and assumptions that often stay hidden. Without clear documentation – the so‑called “paradata” – we risk losing the knowledge that guided the reconstruction and diminishing its scientific value. The IDOVIR project was created to fill this gap. It is a user‑friendly web platform designed to gather all source data, methodological decisions, and reliability assessments of a digital reconstruction. The goal is to create a standardized, accessible workflow for everyone, from seasoned researchers to curious students. So far, the platform has attracted many users and numerous projects are publicly available for consultation and comparison. This allows anyone to verify how a model was built, which sources were used, and what uncertainties were considered. Transparency promotes collaboration, avoids duplicated effort, and makes it easier to assess reconstruction quality. In the future, IDOVIR could become the reference standard for documenting virtual reconstructions, ensuring digital knowledge stays alive and shared.

The IDOVIR framework relies on an extensible metadata model inspired by CIDOC‑CRM standards for cultural heritage management. Users can link each 3D model element to a unique identifier (URI) pointing to external resources: plans, photographs, historical texts, or laser‑scan results. The system records generalisation choices (e.g., surface simplification) and interpretative assumptions (e.g., reconstructing missing parts based on stylistic analogies). Additionally, IDOVIR includes a reliability assessment module that assigns a confidence score to each component, based on criteria such as the number of primary sources, consistency with archaeological data, and expert review. The workflow follows three steps: (1) import raw data, (2) annotate paradata using predefined templates, (3) publish to an open repository under a CC‑BY license. The platform offers interoperability via RESTful APIs, allowing integration with GIS, BIM, and visualization tools like Unity or Unreal Engine. These features enable IDOVIR not only to document but also to make data reusable for comparative analyses, environmental simulations, or educational purposes, fostering a culture of transparency in digital reconstruction.
