建立在醫學數位圖書館中可交換之多媒體架構

隨著網際網路以及電腦科技的進步，越來越多利用多媒體格式呈現的醫學相關資料，例如腸胃道內視鏡影片、耳鼻喉科開刀影片以及理學檢查教學影片等。數位圖書館／博物館的建置，便是在網路上提供具有教育以及文化性質的資料，包括教育圖書、歷史文物、語言文學、宗教藝術以及醫學生物等領域，使用者經由網路瀏覽查詢使用館藏的知識。本研究為建立一個適合醫學數位圖書館之多媒體架構，這個多媒體架構具備可交換、可搜尋以及多樣化呈現之功能。本研究利用Dublin Core建置多媒體Metadata資料庫，詳細記錄多媒體內容，使搜尋界面得以利用Metadata資訊搜尋多媒體資料。呈現方面利用XSL的樣板解讀XML格式之Metadata，使呈現方式可依據XSL的改變而有不同的樣式，並且利用瀏覽器同時呈現圖、文、影、音多媒體資訊。交換界面利用OAI詮釋資料檢索協定，使本研究之多媒體Metadata具備開放檢索的功能。本研究已完成一多媒體資訊系統來證明本研究架構之可行性，對於醫學數位圖書館中多媒體架構之建置具有重要之貢獻，提供未來醫學多媒體研究以及數位博物館／圖書館建置時一個參考的方向，使多媒體資訊達到精確搜尋、完整交換以及多樣呈現的目標。

Because of the advancement of medical technology, we can now obtain a variety of information from the human body with great details. For example, modern techniques such as the digital radiography, computer tomography and magnetic resonance imaging have captured lots of information from human body. In this study, we have developed a multimedia framework that manages a wealth of medical information through the Internet and presents the information in a digital museum/library system. The multimedia framework has the capability of exchanging, storing, retrieving, presenting and managing medical multimedia information. To realize the object described above, the framework was designed to be composed of three parts: the presentation module, the description of data (metadata), and the multimedia database. The metadata was created by using the Dublin Core standard to describe the multimedia information. The metadata was well defined so that it is very convenient to search and exchange data between systems. Different Dublin Core extensions were added for the files with different types and formats. We used XSL to extract Metadata in XML format, so that the presentation style can be changed depending on different XSL definition. Open Archives Initiative is an open protocol for Metadata harvesting. The OAI protocol was used to implement the exchangeable Metadata. With this exchangeable open architecture, medical multimedia data can be manipulated in many different ways and can become reusable for different purpose. The framework developed in this study has great contributions in the fields of Digital Library, medical education and medical research.
