Requirements for Reki-Show Authoring Tools
Operability to handle spatiotemporal dataset
Spatiotemporal database is not easy to use for almost every researchers and students in the field of social science. They don’t have efficient way to handle spatiotemporal dataset by using popular software.(i.e. Microsoft Excel, Access, etc.) It is not impossible, but is annoying. Improving operability to handle spatiotemporal dataset is required.

Requirements for Reki-Show Authoring Tools Capability to visualize spatiotemporal multidimensional information
Usually, social science data is represented as spatiotemporal multidimensional information. The number of dimension vary by the field of concern. To visualize spatiotemporal information by using legacy software, we have to reduce spatial information or temporal information. Because, legacy software are not fitted for multidimensional data visualization. A tools designed for visualization of spatiotemporal multidimensional information is required.

Applied Example -1 Visualization of Peasant Riots in 18th~19th century of Japan
In the late of Edo-era(1840~1868), peasant riots occurred frequently in every part of Japan. We categorized the cause of riot as follows:
Market originated(unfair pricing, corner, etc.) Heavy tax Other reason
Also classified the level of violence as follows:
Direct Appeal (non violent) Direct Appeal (violent) Escape Riot Uprising
Data source:

Visualization of Yukichi Fukuzawa’s Logbook
Yukichi Fukuzawa(1935-1901) is
- ne of famous enlightenment
person in 19th century of
- Japan. He wrote a lot of books
for young people and translated various western
- books. He also founded KEIO
University. Fukuzawa went a round trip to Europe in 1862 as a translator
- f embassy. He wrote a
detailed logbook of the travel, “Seiko Nisshi”. This logbook is a good example of Reki-Show Dataset; spatiotemporal descriptive information. Fukuzawa’s Logbook in Crono-Matrix
