We present an outline of our developing database system of priests in Heian and Kamakura Periods, and then, we report an activity over the last year in which we attempt to display the genealogical tables using SVG. In developing the database system, we have focused on (1) how to register and retrieve literature information, (2) how to register and retrieve person information, (3) how to find and display the human relationship between two persons, and (4) how to make up genealogical trees. By using this system, the re-searchers can register, search, and browse the records efficiently, while they will find novel human relationships behind the genealogical trees. In contrast to the expectations, the displayed genealogical tables have some problems and limitations due to the implementation with Java. To make the tables easy to read and use, we consider and partially implement the visualization system with SVG. We attempt to realize the representation of Chinese characters by embedding the glyph data in the generated SVG files.
