Developing a Governmental Long-term Archive Management System on Semantic Grid

1. Developing a Governmental Long-term Archive Management Systemon Semantic Grid Johannes K. Chiang National Cheng-Chi University, Taipei jkchiang@nccu.edu.tw The project is partially funded by National Archive Administration, TW 姜國輝MIS/NCCU

3. Phase 1: Digitalizing and reformatting of doc’s and Archives Phase 2: Text and Meta-Searching on the Web Phase 3. SRB/SRM, Knowledge-based DataGrid* Phase 4: Long-term archive on Semantic GRID Background of the Development *R. Moore is the one who coined the term 姜國輝MIS/NCCU

4. Objectives and Requirements • Objectives: • to facilitate the long-term Preservation of various kinds of documents, viz. archive, independent from the evolution and changes of time, techniques and digital environments. • Requirements: • Integration of Storage management and Information Management • Secured Preservation of Data, Metadata, Indexes, etc. (value-added Information) • Effective search to resources and efficient storage/access on data • Consistent User-Interface • Recovery drawing on co-location back-up, dynamic regulation on authentication and security management. 姜國輝MIS/NCCU

18. Digital archives on Semantic Grid can be stored and used in a distributed manner, managed in a centralised Catalog/Registry as a whole. Each agency has its own right to manage its storages. Maintaining the consistency (spatially, temporally) of the archiving storages is the most important task for the long-term preservation. Access on replicas leads to better efficiency and reliability. Authentication (roles) management is most crucial for ingestion on this long-term Archive-system. Metadata herewith embraces data and logic relations between documents (content) but also descriptions of physical environments such as format, viewer services used, etc. Name space and naming conventions are of great importance for long-term archiving and have to be robust. Using the mapping between logical and physical file-names allows maintaining the dependency of archives, viz. files, and storage environments. Gov. personnel need training on new skills needed for this re-engineering of Document and Archive Management. Experience learned and future works 姜國輝MIS/NCCU

19. Compliant with the mutual PKI and digital signature techniques resulting from the e-Gov. Project of Taiwan. Survey on XMI for Metadata Interchange Consideration on using RSS and Atom progm’ing for syndicating news as well as the content of governmental sites Future works 姜國輝MIS/NCCU
