For the past twenty-three 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 2009 is sponsored by the ACM Special Interest Group on Applied Computing (SIGAPP), and is hosted by University of Hawaii at Manoa and Chaminade University of Honolulu.
Service Oriented Systems were born with the aim of building large adaptive applications as compositions of loosely-coupled services. Nowadays, in the context of Services we have to cope with a challenge like in the early days of Object-Oriented Programming (OOP) 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 the 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 (e.g. OWL) and the syntactic one (e.g. WSDL). Especially, the role of discovery engines and protocols is not clear. In this respect we still lack adopted standards: a good candidate looked to be UDDI, 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 at using formal methods for specification and verification in this setting have been made. Session correlation, service types, contract theories and communication patterns are only 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.
Service Oriented Architectures and Programming track aims at bringing together 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 Architectures and 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:
