Reki-Show Authoring Tools : Risk, Space and History

Makoto Hanashima, Ken-ichi Tomobe, Tsutomu Hirayama

In social sciences, most events occur in specific time and space. We call such events here "Spatiotemporal Events". It is obvious that events, having always a beginning and an end, appear at a specific place or in particular space. Suppose there exists an conceptual data model regulating some rules to describe those factors, it enables us to store various spatiotemporal events as data and to refer with one another. We, therefore, define a simple spatiotemporal data model, calling "Reki-Show". We also call the information system, consisting of Reki-Show data model, "Reki-Show System", and consider Reki-Show System as the basic information system to deal with the various events in human society. Accordingly, we have recognized that it is indispensable in the future social sciences to have the database and tool for both the temporal and spatial attributes, and have been developing Reki-Show Authoring Tools based on the conceptual framework in Reki-Show System. At present, the fundamental component has been developed already through some steps, and the system is now applied to the empirical research. We would like to make a report of the outline at this stage. This paper explains the basic concept in Reki-Show (Conseptual Data Modeling), followed by the outline of the implemented system.
