certain advantages of service-oriented architecture have led to the spread of this type of architecture around the world. however, some special features of this type of architecture have led to more compromise between the security in the information system and other information systems. the purpose of this paper is to identify and examine the impact of factors and dimensions of the information ...

With the growth of interest on the web services, people pay increasingly attention to the choreography, that is, to describe collaborations of participants in accomplishing a common business goal from a global viewpoint. In this paper, based on a simple choreography language and a roleoriented process language, we study some fundamental issues related to choreography, especially those related t...

Quality of service (QOS) of a choreography is dependent on the quality of service of participating roles. Recently, a proposal has been made to extend the meta model of WSDL to include QOS parameters. These parameters include reliability, availability and demand. In this paper we propose a multidimensional model of quality of service of a choreography based on above proposed extensions. Our pro...

Choreography analysis is a crucial problem in concurrent and distributed system development. A choreography specifies the desired ordering of message exchanges among the components of a system. The realizability of a choreography amounts to determining the existence of components whose communication behavior conforms to the given choreography. Recently, the choreography realizability problem ha...

Global choreographies define the rules that peers should respect in their interaction, with the aim of guaranteeing interoperability. An abstract choreography can be seen as a protocol specification; it does not refer to specific peers and, especially in an open application domain, it might be necessary to retrieve a set of web services that fit in it. A crucial issue, that is raising attention...

From a business perspective, Web services represent a new channel for the offer as well as the acquisition of business capabilities. The full automation of the interaction process between providers and consumers is a peculiarity of the Web service channel. Beyond electronic data transfer, automation extends to all aspects of business interaction. The negotiation of terms and conditions for serv...

This short note outlines two different ways of describing communication-centric software in the form of formal calculi and discuss their relationship. Two different paradigms of description, one centring on global message flows and another centring on local (end-point) behaviours, share the common feature, structured representation of communications. The global calculus originates from Web Serv...

This paper proposes a calculus for describing communication-centred programming and discusses its application to use cases from real business protocols. The formalism, called global calculus, aims at representing global message flows as structured communications. The global calculus originates from the Choreography Description Language (CDL), a web service description language developed by W3C’...

Service computing has increasingly been adopted by the industry, developing business applications by means of orchestration and choreography. Choreography specifies how services collaborate with one another by defining, say, the message exchange, rather than via the process flow as in the case of orchestration. Messages sent from one service to another may require the use of different XPaths to...

Service-Oriented Architecture (SOA) has emerged as an architectural style to foster enterprise interoperability, as it claims to facilitate the flexible composition of loosely coupled enterprise applications and thus alleviates the heterogeneity problem among enterprises. Meanwhile, Model-Driven Architecture (MDA) aims at facilitating the development of distributed application functionality, in...
