This chapter aims at providing a protocol for the comprehensive documentation of cultural heritage: it addresses the need for standardized procedures by targeting cultural heritage operators broadly, emphasizing generalizable methodologies over technical specifics. The outcome of this study aligns with the European approaches to digitalization, and focuses on the clarity, quality requirements, result evaluation, and data management plans. Aligned with a vision of digitalization for cultural heritage preservation, the protocol complements risk management efforts by integrating ongoing monitoring, restoration, and structural integrity assessments. This approach underscores sustainability and economic viability, encapsulated in the guidelines for Documentation Techniques and illustrated through Case Studies.
