[Purpose/significance] Managing sensory information resources in cultural heritage and creating sensory interactive experiences are crucial pathways for cultural heritage conservation and revitalization in the digital age. Com⁃pared to vision and hearing, the sense of smell is a dimension that has not been fully recognized. Revealing olfactory in⁃formation in cultural heritage activation and achieving olfactory reconstruction of cultural heritage is an important and exploratory frontier research. [Method/process] Based on comprehensive literature review, this paper proposes core concepts such as cultural heritage smellscape and its information revelation and digital construction using interdisci⁃plinary theories, methods, and perspectives. Building upon these concepts, an overarching framework for the informa⁃tion revelation and digital construction of smellscape in cultural heritage, relying on the discipline of information re⁃source management, is developed. [Result/conclusion] This framework, with cultural heritage activation as the strate⁃
gic background, centers on olfactory information resources and management, with digitization as the mainline, consist⁃ing of two stages: digital preparation (information revelation) and digital implementation (digital construction), and five components: olfactory information collection, olfactory information organization, olfactory information presentation, ol⁃factory information foundational applications, and olfactory information comprehensive applications. Corresponding to the two stages in the framework, the paper further elaborates on two critical issues: the representation of olfactory infor⁃mation in cultural heritage and olfactory information interaction, and outlines an interdisciplinary methodological sys⁃tem for addressing these issues.
