The Digital Archives Architecture Lab (DAAL) is a working group that provides services, such as systems analysis, construction of systems and consulting services for content holders and service providers. DAAL has developed a set of useful archiving technologies for metadata management, image and video archiving, data format transformation, unencoded Chinese character processing, full text searching, digital rights management, huge image presentation, video broadcasting, and video content analysis. With these technologies, we have constructed about 30 digital archive systems for the National Digital Archive Program and the Taiwan e-Learning and Digital Archive Program, i.e., TELDAP.
To disseminate the huge amount of high-quality digital contents of TELDAP and encourage users to archive and share their own digital contents, we are developing several services to implement the concepts of Web 2.0. The services include 1) VCenter, a video archive and sharing platform based on video streaming technology; and 2) Mozop, a location service that combines user-generated information with web-mining technology to provide location-based information about daily life in Taiwan, e.g., a restaurant guide and the locations of government agencies.
