Service-oriented architecture (SOA) has emerged as a promising paradigm for the inter-organizational sharing of domain-specific capabilities. Perhaps an equally important emergence is the use of SOA to manage the sharing of disparate information within a distributed environment. SOA provides a platform for organizations to enable the user-driven advertisement, discovery, and retrieval of data. A major...
It is accepted that domain based development is playing an important role on IT projects today. Following such idea, this paper presents preliminary study results of a prototype architecture created with the purpose of using a domain-driven approach to shorten the development of software projects. Our discussion presents a way of sharing business domain models, developed in different project sites,...
Some of the characteristics that make service-oriented architectures appealing for enterprise applications also make them vulnerable to security breaches. The vulnerabilities are primarily due to the openness of the service-execution environment, to the dynamic run-time selection and composition of services, and to the autonomy of the individual services. In this paper, we describe these vulnerabilities...
A critical success factor for enterprise application development is to get the systems specifications validated early in the planning and development process. Specification errors that are identified early on in the process are easier and less costly to fix. However, all too frequently business users only discover the impact of specifications once a system is deployed. It is therefore important to...
Creating a service-oriented architecture requires the identification of services to be composed together in order to solve a given need. Currently, software engineers perform this design task by hand by identifying services and how to compose them. In this paper, we propose RuGCo a system to automatically compose Web services coming from a static large repository, according to a domain ontology expressed...
Service-Oriented Architecture (SOA) is an effective paradigm for publishing common features as services and reusing the published services in building applications. Therefore, reusability of services is a key criterion for evaluating the quality of services. The evaluation target for reusability in our model is the service, applied to both atomic and composite service. Reusability models for conventional...
Electronic commerce mechanisms are mainly investigated in two independent research areas: service-oriented computing (SOC) and multi-agent systems. The former as a means to deliver electronic services of various granularity and the latter as a testbed of electronic negotiation mechanisms. However, both research areas heavily rely on each other. On the one hand, service-oriented architectures need...
Semantic Web service composition is about finding services from a repository that are able to accomplish a specified task. The task is defined in a form of a composition request which contains a set of available input parameters and a set of wanted output parameters. Instead of the parameter values, concepts from an ontology describing their semantics are passed to the composition engine. The composer...
Service-oriented architecture (SOA) provides a flexible paradigm to dynamically compose service processes from individual services. The flexibility, on the other hand, makes it necessary to monitor and manage service behaviors at runtime for performance assurance. One solution is to deploy software monitoring agents. In this paper, we present an approach to consider agent cost at process composition...
The capabilities of organizations can be openly exposed, easily searched and discovered, and made readily-accessible to humans and particularly to machines, using service-oriented computing approaches. Artificial intelligence and software engineering researchers alike are tantalized by the promise of ubiquitously discovering and incorporating services into their own business processes (i.e. composition...
The development of mobile services becomes more challenging when context-awareness is taken into account. There are many problems in designing a successful context-aware mobile SOA. In this paper, we introduce the model of "dynamic capabilities" to study how systems can dynamically integrate, compose, and reconfigure internal and external competencies in responding to rapidly-changing environments...
