數位典藏目前大部分的重要資料還是儲存在成熟穩定的關聯式資料庫裏。但為了透過無遠弗屆的網際網路讓使用者便於查詢，資料必須轉換成W3C 所頒佈的標準資料格式XML。計畫主要探討以下兩個問題：（1）XML Publishing：將既存的結構化關聯式資料，轉換成半結構化XML 資料。（2）XML Storage：將接受到的XML 資料，轉換成結構化的格式以儲存於關聯式資料庫。這兩大問題涵蓋的技術相當複雜，包含不同資料格式的對應，不同查詢語言的轉換，所以預計以三年的時間進行。相信本計畫的順利推行，將可發展新技術協助數位典藏的建立，讓使用者查閱上更加便利。The data involved in digital archive are mainly stored in relational database (RDB). These data have to be transformed in XML format (promoted by W3C organization) in order to support web access. We propose to study for fundamental research issue related to this topic, i.e., (1) XML Publishing, and (2) XML Storage. XML Publishing refers to the techniques that transform the structured data stored in RDB to semi-structured data in XML. Secondly, the XML storage refers to accepting semi-structured data in the XML form and transforming such data into structured data in RDB. The problems involved in these two topics are technically difficult, including scheme mapping between various data representation, transformation between different query language (namely XQuery and SQL). We plan to study these problems in a three-year time frame. We believe that the research results from this project are indispensable to archiving the goals of 「National Digital Archives Program
