機讀編目格式與延伸標示語言互轉之定義研究

Study on Schema Definition for MARC and XML Record Conversion

由於XML具備文件格式定義的特點，能夠規範資料著錄的標準依據，使其適合作為各種系統之間，資料交換的理想工具。圖書館界使用資料交換的ISO 2709格式，在使用上因為無法界定資料所屬的MARC、字碼種類，以及資料無法直接呈現在網頁上等缺點，造成許多自動化應用上的限制。因此，本研究採用XML做為書目資料交換格式，分析國內外制定之方法與參酌相關定義內涵，研擬以XML Schema定義書目資料的文件結構定義，提供軟體轉換ISO2709檔案資料與XML文件之間的依據，並透過系統分析方法檢驗其可行性，以確定符合兩者資料格式之間互轉的需求。

XML has become the most standard format of data processing for various kinds of information systems. It contains the feature of document type definition and follows the standard format in data input, so it becomes the ideal tool for inter-system data exchange or transformation. Compared to XML, the ISO 2709 format is limited by certain drawbacks when applied to data exchange. It is neither able to recognize the type of MARC and character code, nor functional in direct presentation on the webpage. The two drawbacks have brought about restrictions on automatic applications. This study adopts XML as the data format for bibliographical data exchange to analyze both foreign and domestic methods for schema formations, with references to interrelated definitions and contents. From the research result, this study plans to construct a software for the data transformation between ISO2709 files and XML documents on the basis of XML Schema. Moreover, the system analysis method will be employed to verify the feasibility of the data transformation.
