Framework for the Development of Environmental Risk Management Services According to the ORCHESTRA Architecture

Abstract

This paper presents the ORCHESTRA Service Container Framework (OSCF) which provides an infrastructure for the development, deployment and execution of services according to the architecture of the ORCHESTRA project (http://www.eu-orchestra.org). Due to the architectural approach of ORCHESTRA the framework is based on a core set of generic ORCHESTRA services which are listed and briefly described. Providing implementations of these services is the foundation for the development of applications and services on the thematic level including risk management services. The OSCF is implemented in Java and is based on Apache Axis2 and the XMLBeans data binding. It offers services and components to support the development of new ORCHESTRA-compliant services and ORCHESTRA service networks. The paper gives examples how the OSCF supports service developers. The access control mechanism is shown which illustrates the interaction between elements of the OSCF. Within ORCHESTRA the OSCF has been used by various pilot implementations based on risk management scenarios. As an example one of the resulting service networks is described in more detail.
