1. S. Yukita, "Design Patterns For Topological Modeling," Cyberworld 2002, IEEE Computer Society Press, pp. 455-462, November 2002.
   Abstract - Topological modeling is a research field that is still in its infant state even though theoretical frameworks are established and various potential applications are proposed. This is due to the lack of design patterns that are shared among researchers and developers of modeling tools. This paper presents some useful patterns derived from experience in developing interactive topological modeling tools, which will accelerate progress in this field.
2. A. Imai and S. Yukita, "HLPM - A High Level Protocol Monitoring Tool for Education," Cyberworld 2002, IEEE Computer Society Press, pp. 397-404, November 2002.
   Abstract - A high level protocol monitoring tool (HLPM) for education is presented. This tool provides an easy interface for learners who have little technical background to understand the design and implementation of Internet application protocols. Using this tool, learners can monitor, test and write interaction scenarios of an application level protocol. The tool incorporates the FESI Script (an interpreter language by Jean-Marc Luring) with which learners can design, implement, and test new network services. HLPM runs on any operating systems that run Java Virtual Machine. The learners can understand the mechanism of a high level protocol by monitoring, and testing the protocol messages. In addition, they can learn how to make the network services by describing the script related to the network. In a word, HLPM offers learners an active study environment of high level protocol by operating an actual network.
3. A. Imai and S. Yukita, "RDF Model and Relational Metadata," Proceedings of the 5th International Conference on Human and Computer 2002, pp. 277-282, Septemer 2002.
   Abstract - In this paper we propose a new metadata type "Relational Metadata" that contains the relational information for retrieving WEB contents. It is based on the eXtensible Markup Language (XML) and using E-R (Entity-Relationship) model of relational datadase (RDB). Relational Metadata is compatible with Resource Description Framework (RDF) through a translator program that can convert Relational Metadata to RDF. The goal of Relational Metadata is to provide the WEB contents creators with easy control over metadata and with automatic RDB integration. Using Relational Metadata, the user can search target information with RDB easily and efficiently. Its retrieval functions are easily customized and optimized according to the personal profile.
