ABSTRACT
State-of-art systems provide comprehensive solutions almost to all users from the data pre-processing through data processing to their final presentation. Consequently, these solutions are very expensive and unavailable for some potential end users. Thus, several questions come up. Do we really need all these functions and, if not why do we have to pay for them? Is it possible to develop such a system with all these functions but without the need of end users to pay extra money for that? In the following text the authors will try to answer the above questions. Web services are a hit of the day. On many experts opinions web services represent a standard for a new information system generation. A prove of this statement could be the fact that every new software product support this form of the internet use. Also in the geoinformatics, this facility is successfully used for a long time (e.g. WMS, WFS). But as all, even web services are further developed and also native protocols, based on the XML format, are subsequently replaced by general protocols (e.g. SOAP).These protocols also use XML, but they enable the development of distributed systems with paralleled features using the Internet as a communication middleware. Thus, it is possible to develop wide information systems with a high level of modularity and integration with existing systems. The paper describes the architecture for the development of open and modular systems.
