Research paper : Information sharing platform to assist rescue activities in huge disasters (I. Noda)−118−Synthesiology - English edition Vol.5 No.2 (2012) be explained in subchapter 4.2, we succeeded in receiving over 8,000 reports from residents in 30 minutes and linking them with other information systems and simulations, using an old model laptop PC (Mobile Pentium III 933 MHz, memory 512 MB). This performance is sufficient for disaster information system linkages of a medium sized city, and information systems can be operated on PCs no longer in use in times of emergency. To enable this, we also created the Linux live images where the DaRuMa will run automatically when booted from a USB.Concurrently with the development of DaRuMa, the development and organization of the tools to connect the DaRuMa and various systems are done. In the mitigation information sharing platform, all modules communicate with DaRuMa by MISP. However it is not realistic to make all the currently existing disaster information system MISP compatible. Rather, it is more practical to achieve partial linkages using the functions of the existing systems and to gradually deepen the linkages when the system is updated, as shown in the right half of Fig. 6. As listed below, the DaRuMa tools are being developed to support such partial linkages. CSV connection toolThis is a tool to convert the data output in a comma separated value (CSV) format into XML and to register them to DaRuMa through MISP. It is also a tool to convert the data obtained by MISP into CSV format. Many disaster information systems support the input/output of CSV files that is the universal data format of the spreadsheet software. Partial linkages may become automated by organizing this connection tool. For linkage automation, the functions of regular input/output of the temporal difference data and of setting the condition for data acquisition from DaRuMa are included. GIS viewer linkage toolThis is a tool to convert the information (features) stored in DaRuMa linked with the position on the map to KML, and to display them on GIS viewer such as GoogleEarth and GoogleMap. In disaster information where the features will be relevant, it is important to check the information stored in the database on a map as needed to maintain linkages among the modules. The free or low-cost, high-performance GIS viewer such as GoogleEarth is effective as a means to provide information to related organizations, as well as providing linkage support, and the presence of connection tools is important in utilizing the existing software. Log replay toolThis is a tool to utilize the log recorded with timestamp of database maneuver and MISP communication to DaRuMa, and to reproduce the flow of situations of shared information according to time steps. When adjusting the linkages of multiple modules, it may be difficult to keep all modules in usable status. Particularly, when conducting linkages across multiple organizations and institutions, they have limited opportunities to connect modules for linkage adjustment. Since the log replay tool will allow pseudo-reconstruction of the recorded receiver module activities, it is possible to simplify the linkage adjustment. This tool can also be used when conducting simulated joint training exercise.3 Disaster information system linkage based on data mediation3.1 Lifecycle of a system and continuity of dataFig. 6 System linkage by mitigation information sharing protocol (MISP) and DaRuMaFig. 5 Structure of DaRuMaMySQL/PostGISSQLMISP processor(Java)DaRuMaMISPApplicationsNewly developed applicationsExisting applicationNativeMISPapplicationJava applicationC++/C#applicationExistingXMLapplicationExistingGISapplicationExistingCSVapplicationXMLconversionCSVconversionGIS formatconversionMISPlibrary(java)MISPlibrary(java)MISPlibrary(java)MISPlibrary(java)MISPlibrary(C++/C#)DaRuMaMISP
