For the past twenty-four years, the ACM Symposium on Applied Computing has been a primary gathering forum for applied computer scientists, computer engineers, software engineers, and application developers from around the world. SAC 2010 is sponsored by the ACM Special Interest Group on Applied Computing (SIGAPP), and is hosted by University of Applied Sciences, Western Switzerland (HES-SO) and Ecole Polytechnique fédérale de Lausanne (EPFL), Switzerland.
Although when considered from a purely technological point of view Service-Oriented Computing (SOC) is not an enormous novelty, , when considered from a programming paradigm perspective it is quickly changing our vision of the Web. Originally, the Web was indeed mainly seen as a mean of presenting the information to a wide spectrum of people, but SOC is triggering a radical shift to a vision of the Web as a computational fabric where loosely coupled services interact publishing their interfaces inside dedicated repositories, where they can be searched by other services, retrieved and invoked, always abstracting from the actual implementation. In the context of this modern paradigm we have to cope with an old challenge, like in the early days of Object-Oriented Programming when, until key features like encapsulation, inheritance, and polymorphism, and proper design methodologies were defined, consistency in the programming model definition was not achieved. The complex scenario of Service Oriented Programming needs to be clarified on many aspects, both from the engineering and from the foundational point of view.
From the engineering point of view, there are open issues at many levels. Among others, at the system design level, both traditional approaches based on UML and approaches taking inspiration from business process modelling, e.g. BPMN, are used. At the composition level, although WS-BPEL is a de-facto industrial standard, other approaches are appearing, and both the orchestration and choreography views have their supporters. At the description and discovery level there are two separate communities pushing respectively the semantic approach (ontologies, OWL, ...) and the syntactic one (WSDL, ...). In particular, the role of discovery engines and protocols is not clear. In this respect we still lack adopted standards: UDDI looked to be a good candidate, but it is no longer pushed by the main corporations, and its wide adoption seems difficult. Furthermore, a new different implementation platform, the so-called REST services, is emerging and competing with classic Web Services. Finally, features like Quality of Service, security and dependability need to be taken seriously into account, and this investigation should lead to standard proposals.
From the foundational point of view, formalists have discussed widely in the last years, and many attempts to use formal methods for specification and verification in this setting have been made. Session correlation, service types, contract theories and communication patterns are only a few examples of the aspects that have been investigated. Moreover, several formal models based upon automata, Petri nets and algebraic approaches have been developed. However most of these approaches concentrated only on a few features of Service Oriented Systems in isolation, and a comprehensive approach is still far from being achieved.
The Service Oriented Architectures and Programming track aims at bringing together, for the second year, researchers and practitioners having the common objective of transforming Service Oriented Programming into a mature discipline with both solid scientific foundations and software engineering development methodologies supported by dedicated tools. In particular, we will encourage works and discussions about what Service Oriented Programming still needs in order to achieve its original goal, along with works proposing comparisons among different models and technological solutions.
Major topics of interest will include:
Authors are invited to submit original unpublished papers using the eCMS site :
Submission of the same paper to multiple tracks is not allowed. Authors are allowed up to 8 pages but with more than 5 pages in the final camera ready, there will be a charge of 80USD per extra page. Peer groups with expertise in the track focus area will blindly review submissions. Accepted papers will be published in the annual conference proceedings. Submission guidelines can be found on SAC 2010 Website:
The author(s) name(s) and address(s) must NOT appear in the body of the submitted paper, and self-references should be in the third person. (this is to facilitate blind review required by ACM). All submitted papers must include the paper identification number on the front page, above the title of the paper provided to you by the eCMS when you register your paper.
