    Alarm Reporting in River Information System
    (Managing Environmental Knowledge, 2006) Bec, Sonja; Pecar-Ilic, Jadranka; Skocir, Zoran
    This paper gives a description of the most significant parts of the development of the Alarm Reporting Subsystem of the River Information System (River IS). River IS will provide efficient waterway related data management at national level for the Croatian part of the Danube River. Our research in that area dates from the year 2000, and since 2003 is carried out within the CROatian River Information Services (CRORIS) project. In this paper, first the main functionalities of River IS are outlined, and then the alarm reporting process is described in detail. We were interested in alarms and regular status checks from buoys and floats positioned along the river and regular status checks of displays from the bridges. Provision of measurement data from the floats as well as water level data along the river was also required. For modeling of the requirements the UML Use Case diagram was used and based on it and the characteristics of chosen SVG (Scalable Vector Graphics) and Web technologies the Class diagram representing the Static Structure was developed. Along with the description of the diagrams, especially the characteristics of the alarming and SVG technologies were discussed. In the end, an example of the map interface with explained access to reports is shown.

    Architecture of River Information System with Automatic XML Processing
    (The Information Society and Enlargement of the European Union, 2003) Bec, Sonja; Pecar-Ilic, Jadranka; Ruzic, Ivica
    In this paper the River Information System architecture is formally described at the highest level by the standard Unified Modeling Language (UML). UML package diagram, which represents necessary packages (subsystems) and their mutual communication, was created. Based on that description the detailed Object Oriented (OO) development of each subsystem can be performed later. Here we propose a solution using eXtensible Markup Language (XML) as the format of exchanged data. The example of the automatic eXtensible Markup Language (XML) processing is described as well. These activities are a part of the CRORIS programme carried out by the Rudjer Boskovic Institute and the Ministry of Maritime Affairs, Transport and Communications of the Republic of Croatia.
