The business process execution language (BPEL) is a language to orchestrate web services into a single business process. In a choreography view, several processes are interconnected and their interaction behavior is described from a global perspective. This paper shows how BPEL can be extended for defining choreographies. The proposed extensions (BPEL4Chor)(More)
Interconnecting information systems of independent business partners requires careful specification of the interaction behavior the different partners have to adhere to. Choreographies define such interaction constraints and obligations and can be used as starting point for process implementation at the partners' sites. This paper presents how the Business(More)
TOSCA is a new OASIS standard to describe composite applications and their management. The structure of an application is described by a topology, whereas management plans describe the application's management functionalities, e. g., provisioning or migration. Winery is a tool offering an HTML5-based environment for graph-based modeling of application(More)
Portability and automated management of composite applications are major concerns of today's enterprise IT. These applications typically consist of heterogeneous distributed components combined to provide the application's functionality. This architectural style challenges the operation and management of the application as a whole and requires new concepts(More)
The Business Process Modeling Notation (BPMN) and the Business Process Execution Language (BPEL) are the de-facto standards for process modeling and implementation. While BPMN allows to define choreographies, i.e. the interaction behavior of interconnected services, BPEL only allows an endpoint-centric view on services. To achieve applicability of BPEL in(More)
The most prominent business process notations in use today are BPMN, EPC and BPEL. While all those languages show similarities on the conceptual level and share similar constructs, the semantics of these constructs and even the intended use of the language itself are often quite different. As a result, users are uncertain when to use which language or(More)
Business process monitoring in the area of service oriented computing is typically performed using business activity monitoring technology in an intra-organizational setting. Due to outsourcing and the increasing need for companies to work together to meet their joint customer demands, there is a need for monitoring of business processes across(More)
