ENTERPRISE SERVICE BUS FOR GEOWEB SERVICES

INSPIRE directive prepared rules how to integrate several different geodata sources. If the sources are available according to the rules, anyone can create a tool generally named geoportal. A geoportal allows to access different geodata sources via one logical access point. This kind of tool is a typical example of geoinformation systems integration. Such integration can be done in many specific ways. When dealing with information systems integration we always looking for solution that will be the most efficient. There are several ways of integration very nicely and in detail described by Gregor Hohpe and Bobby Woolf in the excellent book Enterprise Integration Patterns. To select the best option is very difficult. We have decided to research one possible option in the area of GeoWeb services. This option based on Enterprise Service Bus (ESB) is quite new even for integration based on non geospatial services. The paper will discus one example when is probably efficient to use ESB and one example when the usage of ESB will not be very efficient (may not be even effective). There is a second step, in a case of selection of ESB way, to select appropriate software tool. For research purposes were analysed three main open source solutions: MULE ESB, Service Mix and Open ESB. The paper is going to describe each of them very briefly and compare them from selected points of view. The last part of the paper will be focused on description of a prototype that allows plug-in GeoWeb Services into ESB selected for the research, which is MULE ESB.
