| Abstract: |
| This paper investigates the challenging issues and technologies in managing very large digital contents and collections, and gives an overview of the works and enabling technologies in the related areas. Based on the analysis and comparison of the related work, a novel architecture of massive information management for digital library is designed. The key components and core services are described in detail. Finally, a case study THADL (Tsinghua University architecture digital library) that complies with the architectural framework is presented. |
