4.       Some Technical Considerations

=TSL-GIS

The core technology is another essential point in this project. To cope with the content space, besides adopting and developing various information technologies, geographical information system (GIS) is utilized as a common framework for spatial data processing. And, a dedicated and global support in linguistic and scriptural issues for all contents is established .The digital information life cycle is enforced to establish solid procedures from creation, accessibility, management, storage and presentation of digital information. The design and implementation for providing intellectual access to stored information, from users, content providers, and system builder’s aspects, are discussed. On the other hand, collaboration and outreach are also crucial points in the development of TDA.

Temporal, Spatial and Lingual (TSL) three mutually orthogonal axes construct the content space. We called them “TSL coordinates”, as shown in Figure-3. The integration of TSL coordinates onto the GIS is called the TSL-GIS in our system. At present, although we already have a complete set of digitized China and Taiwan historical GIS, but the TSL-GIS is now in developing stage. Not only because of the intrinsic property of TSL-GIS will provides general references for timing and addressing, but also the scalability and localization concerns in scope for a robust TDA data architecture. These TSL coordinates and relevant technical conventions, standards and specifications are the most important factors that make unite various digital products into TDA possible. From the content point of view, a research database will be the solid foundation of the whole TDA. Based on that, a learning database could be built for different educational purposes. Furthermore, it could be extended and compiled to be a popular and easy-to-understand database for all walks of life.
