Choreographies are an emergent Service Engineering approach to compose together and coordinate distributed services. They represent a global specification of the interactions between the participant services. BPMN2 provides a dedicated notation, called Choreography Diagrams, to define choreographies. This paper presents a model transformation to automatically transform a BPMN2 choreography spec...

Ubiquitous coming from the Latin word ubique, means existing or being everywhere, especially at the same time. Web Services are loosely specified and coupled components distributed over the internet [23] with the purpose of being accessed and used ubiquitously by suppliers, customers, business and trading partners. This must be done independently of any tools or environment in use by any party ...

The composition of web services enables the cooperation going through organizational boundaries, allowing new and complex scenarios for collaboration. Middleware, and particularly reflective middleware, have been used as a powerful tool to cope with inherent heterogeneous nature of distributed systems and to give them greater adaptability capacities to face their environment. In this paper we p...

Interactions between services may be globally captured by choreographies. We introduce BPEL supporting modeling interaction choreography models using BPEL. We show the usage of BPEL in an enterprise service bus to ensure an executed message exchange complies with a pre-defined choreography.

With increased sophistication and standardization of modeling languages and execution platforms supporting business process management (BPM) across traditional boundaries, has come the need for consolidated insights into their exploitation from a business perspective. Key technology developments in BPM bear this out, with several web services-related initiatives investing significant effort in ...

Alice&Bob notation is widely used to describe conversations between partners in security protocols. We present a tool that compiles an Alice&Bob description of a Web Services choreography into a set of servlets. For that we first compute for each partner an executable specification as prudent as possible of her role in the choreography. This specification is expressed in ASLan language, a forma...

The focus of this work is set on business processes spanning across multiple business partners. Such business processes are called choreographies. This work presents the method CREAM which allows modeling choreographies. In contrast to choreographies, orchestrations denote executable business processes of one organization, which use services to realize a business goal. A variation of CREAM enab...

Choreography has recently emerged as a pragmatic and concise way of describing communication-based systems such as web services and financial protocols. Recent studies have investigated the transition from the design stage of a system to its implementation providing an automatic way of mapping a choreograhy into executable code. In this work, we focus on an extension of choreography with a comm...

Standardisation of the description and delivery of distributed XML-based ‘web services’ has opened up a market, larger than any before, in ‘commercial off the shelf’ (COTS) software components. As a result, agreements are being reached on the assembly of systems from web services where the choreography if defined by workflow languages such as BPEL. With several potential implementations for man...
