Research paper : Information sharing platform to assist rescue activities in huge disasters (I. Noda)−126−Synthesiology - English edition Vol.5 No.2 (2012) Discussions with Reviewers1 Organization of the main points as a Synthesiology paperComment (Hideyuki Nakashima, Future University Hakodate)This is a paper on the disaster information system realized by system linkages through data mediation. Its objective is to link the various and the future information systems, or to synthesize open systems where not everything can be predicted beforehand, and I think it is very appropriate as a Synthesiology paper.As the editorial policy of Synthesiology, we expect a clear statement of the basic policy for the construction of such an open system. In fact, such a basic policy is actually written in the text of this paper. However, although I can understand the individual descriptions well, I think you should clarify the overall concept to help readers understand. Particularly, I think you should emphasize the “synthesis method,” and provide descriptions with emphasis on the service engineering methods.In chapter 1, you give the three basic policies of design: “open system, standard, and downward scalability.” On the other hand, you also state the concept of data-centered (or data mediated linkages) in subchapter 2.1 and chapter 3. In subchapter 2.3, you give the two points of design and implementation policy: 1) downward scalability and multi-platform, and 2) utilization of existing software and open sourcing. The relationships among these points are not clear. I think you should organize the overall concept and provide descriptions using diagrams or tables.As a proposal, I think you can give the characteristics that a disaster information system should possess, position the requirements in a top-down manner, and then position the corresponding implemented functions. Is my following understanding correct?Characteristics of disaster information• Various organizations (as well as individuals?) operate the disaster information system at varying scales.• Difference in timescale of the disaster and the information technology• Disaster measures must be updated frequently, and in some cases, complete makeover is necessary.The system linkages by data mediation are optimal as the linkage platform that fulfills the above objectives. The requirements to realize such a platform are as follows:• Simplify the new linkage connections• Maintain universality: universal input format, universal output format, common structure, etc.• Simplify the task for new linkages• No need to consider computational capacityThe functions that came up as issues in implementation were as follows:• Module linkages mediated by data: to link the various disaster information systems• Data structure definition function: to test and update the new data format in real time when a new module is added• Employ standards for the basic function of MISP: to increase compatibility with the existing and future systems. It should be simple, and should be capable of being handled by sensor systems without computational capacity.• Employ XML: universality, flexibility, expandability• Low requirement of operating environment: assuming that large servers may be down, it must run on small terminals• Open sourcing: establish the framework of information sharing and allow smooth diffusion• Tools to allow linkages, even partially, without limiting to MISP CSV connection tool: system widely supports the universal data format of spreadsheet software GIS viewer linkage tool: tool for displaying data on GIS viewers such as GoogleEarth Log replay tool: tool for reconstructing the changes in shared information of the various modules, including the time axis. Simplifies adjustment of linkages.I think if you add tables or figures that show the relationships of these functions and the requirements in matrices, it will clarify the synthetic concept (research scenario) toward the research goal, and provide useful information as a Synthesiology paper to the readers.Answer (Itsuki Noda)Thank you very much for your useful advice. As you indicated, the flow of the entire paper and the relationships of the keywords were difficult to understand. I added some texts to chapter 1 to supplement the explanations. I also added figures to show the relationships of the keywords.2 TitleComment (Motoyuki Akamatsu, Human Technology Research Institute, AIST)Please add a title and subtitle that clarify the above points. For example, “Construction of a platform for disaster information system linkage – Linkage of various information systems that change over a long period via data mediation.” Please consider this along with the main points.Also, please reconsider the subchapter titles of chapter 3 to clarify the main points of the paper.Answer (Itsuki Noda)For the title, I added “platform” which is the proposed technology. For the subchapter titles of chapter 3, I used the keywords discussed in subchapter 3.1 to clarify the corresponding relationships. I also added the subchapter numbers to the keyword relationship diagram in Fig. 1.3 DaRuMaQuestion (Motoyuki Akamatsu)When I look at Fig. 7, it seems that there were two DaRuMas made, one for Niigata and the other for Mitsuke. Did you need two systems for smooth operation? Please explain why you had two DaRuMas.Answer (Itsuki Noda)During the experiment at Mitsuke City, there was no access control on DaRuMa, and all systems that could access DaRuMa could see all the information there. Therefore, the information that had to be kept closed within the city hall and offices could not be loaded to DaRuMa, and information sharing in the offices was stopped. To prevent this, we set up the internal DaRuMa and external DaRuMa, installed a mirroring tool with filtering functions, and only the information that can be released publicly was reflected in the external DaRuMa. Later, access control was added to the DaRuMa (and MISP) so such a dual setup is no longer necessary. In this paper, I describe the system configuration used during the experiment. Since access control is not the main subject of this paper, I will not include the explanation.4 MapQuestion (Motoyuki Akamatsu)In this paper, you present the demonstration at Mitsuke City, demonstration at Toyohashi City, and Honda’s Toreta Doro Map. I think it is extremely important to do the demonstrations on site, but what were the backgrounds in which you obtained permission
