數位圖書館系統所用到的技術相當多，如資料數位化、浮水印、內容檢索、網路安全與認證、Metadata、多媒體、多語文，及XML技術等，其中Metadata與XML更是發展數位圖書館系統的核心技術。本文將說明臺灣發展Metadata之現況，並以個人的實際經驗說明Metadata發展的步驟，以及介紹以XML技術所開發Metadata管理系統之發展理念及其功能。

Among the many technologies applied in digital library system, metadata and XML prove to be the core technologies involved in the development of this system. This paper first introduces the current development of metadata in Taiwan and then describes the process of the metadata development of Metalogy and the concepts and functions of this management system.

數位物件辨識系統(Digital Object Identidfier System, DOI System)為一可在數位環境下獨特辨識、描述與連結智慧產物的系統。本研究參考DOI系統架構，依據國內之環境實際建置一套〈LIPS-DOI〉系統，包含列舉、描述與解析模組。以延伸標記語言(Extensible Markup Language, XML)為基礎發展詮釋資料架構，以簡單都柏林核心集(Simple Dublin Core)作為核心應用描述檔案格式，並提供代理解析服務。

The Digital Object Identifier (DOI) system is a system for identifying and ex-changing intellectual property in the digital environment. With reference to the DOI's framework, an experimental system named based on Taiwan's environment is reported in this article. This system mostly resembles the DOI system in its three modules: numbering, metadata and resolution. The system framework is based on XML technology, the Dublin Core is used as the Application Profile, and a resolution proxy service is provided as well.
