This work provides an institutional framework for digital records management within the State Archives of Belgium. It outlines the principles, procedures, and standardized structures for organizing, naming, storing, and selecting documents across all departments. The guide introduces a unified classification system (RM_DATA, SHARED_DATA_INT, SHARED_DATA_EXT, MY_DATA) designed to improve consistency, accessibility, and long-term preservation of both paper and digital records. It defines mandatory rules for directory structure, file naming conventions (including date formats and versioning), and responsibilities of staff members such as RM Officers and the RM Team. The manual also describes specific management procedures for emails, financial documents, acquisition and loss of archives, collection care, and digital preservation. Its overall objective is to ensure efficient information management, safeguard authenticity, and support transparent archival workflows across the entire institution.Version 1.0
