Research on multi-dimensional collection methods for historic building heritage information has become increasingly comprehensive. However， the interaction among various types of heritage information suffers from inconsistent content and format， which hinders effective utilization. This article focuses on historic timber buildings from the Ming and Qing dynasties， presenting a systematic approach for establishing an industry foundation classes （IFC） framework. Through analysis， heritage information during the protection process is categorized into five core dimensions： architectural， historic， artistic， degradation， and restoration. Based on the CIDOC conceptual reference model （CRM）， knowledge graphs for Ming and Qing historic timber buildings were created for each dimension heritage information. Additionally， the corresponding elements of heritage information expression were integrated and aligned with the IFC architecture framework， ultimately leading to the establishment of the IFC expression framework for Ming and Qing historic timber buildings. By systematically organizing the IFC heritage information of Ming and Qing history timber buildings， standardized solutions are provided for the construction of the IFC framework of history buildings. This approach promotes the efficient sharing and application of historic building heritage information.
