Paper proposes a solution for extending the SOA/Web Services with support for business events and EDA concepts. Our solution enables services to act as event producers and event consumers. It also enables event-driven service orchestrations in business processes. We propose specific extensions to WSDL and BPEL, and a flexible XML representation of the event payload data. We introduce event sinks, sources, and triggers.

Paper proposes a unified taxonomy and an IaaS architectural framework, structured around seven layers: core service layer, support layer, value-added services, control layer, management layer, security layer and resource abstraction. It surveys various IaaS systems and maps them onto the taxonomy to evaluate the classification. It also introduce an IaaS architectural framework that relies on the unified taxonomy, provides a detailed description of each layer and defines dependencies between the layers and components. Finally, it evaluates the proposed IaaS architectural framework on several real-world projects, while performing a comprehensive analysis of the most important commercial and open-source IaaS products.

Paper proposes a solution to describe a complete set of structural constraints for a particular business object in all its use cases, based on the XML Schema (XSD), de facto standard for description of web service message structure. It proposes XSD extensions that realize two distinct and complementary approaches. Measurements have shown that by using these extensions the average complexity of real world schemas (XSD documents) comparing to expressional equivalent alternatives is smaller by ~29%.

These papers address various aspects of business processes and propose extensions and improvements to their underlying technologies, such as WS-BPEL, WSDL, UDDI, web services and service selection. Proposed solutions simplify and improve implementation and execution of these processes.

Monographs address the field of service oriented architecture (SOA) and design patterns. They present innovative aspects of BPEL usage in the field of integration and composition, and patterns for integration. Monograph WS-BPEL 2.0 for SOA composite applications was the first one on this topic in the world and places itself among publisher’s best sellers. Mentioned monograph contributions are important for wider field of information systems development and information science. One of the monographs was awarded as the best SOA book in the world in the year 2007 by the SOA World Journal.
