Digital narrative as the breaking up and reconstructing of the elaboration network elements around the background, attributes, purpose and logic of the narrative subject, and finally as the multi-layered, multi-dimensional and multi-perspective data insight narrated in the form of multi-media, provides space for imagination for the future development of archival content management. According to the three stages of archival datalization, data knowledge discovery and knowledge narrative, this paper predicts the development trend of archival content management from the perspective of digital narrative, and believes that the future archival content management process will realize a three-dimensional orthogonal decomposition architecture: vertical extension, horizontal expansion, deep support. On this basis, three dimensions of archival data resource ecosystem construction are proposed: dynamic balance of archival data resource ecological elements, multi-subject collaborative archival content service, and multi-source and heterogeneous archival data sharing.
