XML Technology Research Lab

Currently, many systems are under development. Also, a simple weblog was established. New features will be added whenever they are available. So, check back often.

Current Research Porjects:

e-Learning and Semantic Web

The Advanced Distributed Learning (ADL) initiative has developed a data sharing standard called Sharable Content Object Reference Model (SCORM) to improve data exchanges, sharing, and reuse in e-Learning environment. One of the major components that makes SCORM accomplish what it claims is the usage of metadata. However, the proposed metadata used in SCORM is limited. With the emergence of Semantic Web, we believe e-Learning systems can have much improved data exchanges, sharing, and reusability.

XML Security

XML has become a standard format for data interchanges on the Internet -- especially in the electronic commerce. Although it is extremely important to protect XML documents from being illegally modified, the development of XML security is still in its infancy stage. In this project, our focus is on access control on Web-based information systems and applications of cryptography on commerce information systems.

RDF-based Peer-to-Peer System

Due to the emerging of P2P technology, the concept of P2P has been applied in many Internet applications such as file sharing, instance messaging, and distributed computing. As a result, many researches had been devoted to improve the efficiency of P2P application routing protocols. Many protocols such as Freenet, Pastry, and Chord had been proposed. However, this type of research cannot ensure the shared resources can be found when the amount of shared resources is huge and their diversity is high. To resolve the problems, semantic-based P2P systems were proposed. In semantic-based P2P systems, each shared resource is described by some metadata. With metadata, the resources can be correctly located. In addition, because application routing protocols can take advantages of these metadata, the number of query packages can be reduced. Also, only the "possible" route will be used.
