For the past twenty-eight 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 2013 is sponsored by the ACM Special Interest Group on Applied Computing (SIGAPP), and is hosted by Institute of Engineering of the Polytechnic Institute of Coimbra (ISEC-IPC), Portugal.

Service-Oriented Programming (SOP) is quickly changing our vision of the Web, bringing a paradigmatic shift in the methodologies followed by programmers when designing and implementing distributed systems. Originally, the Web was mainly seen as a means of presenting information to a wide spectrum of people, but SOP is triggering a radical transformation of the Web towards a computational fabric where loosely coupled services interact publishing their interfaces inside dedicated repositories, where they can be discovered by other services and then invoked, abstracting from their actual implementation. Research on SOP is giving strong impetus to the development of new technologies and tools for creating and deploying distributed software. 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 SOP needs to be clarified on many aspects, both from the engineering and from the foundational points 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 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 concentrate 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 researchers and practitioners having the common objective of transforming SOP into a mature discipline with both solid scientific foundations and mature software engineering development methodologies supported by dedicated tools. In particular, we will encourage works and discussions about what SOP still needs in order to achieve its original goal.
