儲存體為儲存電子檔案的系統,必須能夠管理內容物件及其描述資料,並能夠在標準之間有一定的相容程度。美國Advanced Distributed Learning Initiative提出CORDRA架構,希望透過此架構讓學習元件能夠被發現與重複使用。本研究實做一個CORDRA架構的系統,稱為MINE Registry,提供使用者註冊SCORM標準的課程,系統會紀錄此課程的描述資料,儲存課程,並記錄課程重複使用的關係。透過搜尋引擎找到符合條件的學習元件及重複使用的關係。 學習元件在搜尋時必須根據描述資料搜尋,課程設計者常忽略編輯描述資訊,透過Meta-data Wizard可以幫助課程編輯者在製作課程時自動填入課程的某些描述資訊,減少課程設計者的負擔。 Repository is a system which stores electronic files. The basic requirements are Meta-data Management, Content Management and Interoperability. Advanced Distributed Learning Initiative proposes CORDRA architecture which can register learning content and raise the reusability of content. In this research, a CORDRA-based repository system, named MINE Registry, is implemented. MINE Registry provides a portal for users to register SCORM-compatible courses. Not only the meta-data will be stored, but the reusability tree will be built. The Search Engine retrieves content and reusability trees which fit the search criteria. The meta-data is necessary if a repository system wants to search for content. The editing of meta-data is often ignored by course developer. This study constructs a Metadata Wizard based on Deduction Engine to fill in metadata automatically. Not only the completeness of meta-data in SCORM specification can be achieved but also the total costs in meta-data generation can be reduced.
