Representation of Meta-Paradata for H-BIM Models in WebGIS: Paving the Way Towards '3D Scientific Models'

Ensuring authenticity and reliability of 3D models of Cultural Heritage (CH) data is increasingly critical, especially considering the increasing adoption of Artificial Intelligence (AI) in generating content. This paper highlights the importance of metadata and paradata to ensure transparency, authorship, and scientific rigor and considers challenges in creating metaparadata information and its visualization on the web alongside 3D content. The study proposes a new meta-paradata schema for document-based Historic-BIM (H-BIM) models. It explores the integration of this schema into WebGIS platforms through tests on models from the Turin 1911 project. The goal is to promote best practices for accessible, georeferenced, and verifiable ‘3D scientific models’, while preserving CH narratives in virtual ‘scrollytelling’ environments.
