Responding to the rapidly growing market share for Information Systems (IS) based on Service-Oriented Architecture (SOA), the demand emerges for methods of measuring the value of SOA-based IS projects. The goal of the present research is to adapt available methods of project assessment to this expanding demand. This study describes a new method which takes into consideration a possibility to divide deployment and evolution of SOA-based IS into separate flows, one per service. Like that the process of value assessment could become more precise and exact compared to other known methods which use the single flow for the whole project. In addition the work proposes Real Options for calculating such components of the value as flexibility. The described method is validated using a specific simulation model. Value assessment of a real IS project is performed using the developed method and the simulation model.

Ontologies at the present time are generally rich data models. The interoperating information system engineering paradigm Service-Oriented Architecture recognizes that the key issue in interoperating information systems is the actions performed by these systems, not so much the data. Further, the organizationally heterogeneous nature of these interoperating systems means that the individual object is difficult to characterize by classes. This chapter investigates the problems raised by giving priority in ontology representation to individuals and actions over classes, outlining a number of significant research questions in representation languages for ontologies.

In many countries, governments have been developing electronic information systems to support in labour market in form of on-line services, web-based application as well as one-stop service. One of the biggest challenges is to facilitate the seamless exchange of labour market information (LMI) across governmental departments. This chapter introduces an efficient implementation of Thailand’s e-government interoperability project in LMI systems using service oriented architecture (SOA) based on XML web service technology. In Thailand, the Ministry of Labour (MOL) has developed a Ministry of Labour Operation Center (MLOC) as the center for gathering, analyzing and monitoring LMI to assist the policy makers. The MOL consists of four departments: department of employment, department of labour protection and welfare, department of skill development, and social security office. Thsse departments utilize electronic systems to manage LMI such as employment, labour protection and welfare, skill development and social security. Provincially, MOL has 75 branches called “labour provincial offices” located at 75 provinces in Thailand. Each office has developed a “Provincial Labour Operation Center or PLOC” as the operating center in the province where the information system called “PLOC” system has been developed to analyze and monitor the localized labour information for the provincial policy-makers. Since these systems differ, it requires the process of data harmonization, modeling and standardizations using UN/CEFACT CCTS and XML NDR for achieving the common XML schema standard, with the implementation of SOA to integrate efficiently all those systems. We apply TH e-GIF guidelines for interoperable data exchanges and the XML schema standardization. In Thailand, the first Thailand e-Government Interoperability Framework – the TH e-GIF - came into being in November 2006. This chapter illustrates main concepts of TH e-GIF, the project background and methodology as well as key leverage factors for the project.

As Web service technologies mature in recent years, a growing number of geospatial Web services designed to interoperate spatial information over the network have emerged. Geospatial Web services are changing the way in which spatial information systems and applications are designed, developed and deployed. This chapter introduces all aspects of geospatial Web services from service-oriented architecture to service implementation. It covers the life cycle of geospatial Web services in terms of geospatial interoperable standards, including publish, discovery, invocation and orchestration. To make geospatial Web services more intelligent, semantic issues about geospatial data and services are discussed here. Furthermore, the applications of standard-compliant geospatial Web service are also reviewed.

Service-oriented architecture (SOA) is currently the predominant software integration framework. Web services provide the predominant platform for SOA. SOA as an integration architecture solution supports a range of application scenarios. We present a solution for the integration of business information systems based on SOA and Web services. We discuss maintainability requirements in relation to information-specific integration and architecture aspects. A template-based approach based on modular and declarative transformation rules and architectural styles and patterns defines our solution to the maintainability problem of integration architectures.

Real time impact in many applications is the subject of a recent field of studies in information systems. Web services are a solution for the integration of distributed information systems that are autonomous, heterogeneous and auto adaptable to the context. This impact can resolve many problems in different systems based on Service Oriented Architecture (SOA) and web services. In this paper, the authors are interested in defining an approach to provide the different needs of self-adaptability of SOA to the context based on workflow, define the real time goal in their approach and show the feasibility and performance evaluation of their approach in an ambulance trajectory case study.

Healthcare is an increasingly collaborative enterprise involving many individuals and organizations that coordinate their efforts toward promoting quality and efficient delivery of healthcare. To these ends, today, more than any other point in time, increased reliance is being placed on interoperability among healthcare information systems (HIS) which have been developed as monolithic, stand-alone systems without significant interfaces between them. Enabling heterogeneous HIS to interact within a Service-oriented architecture (SOA), such as a Web Services architecture, can help healthcare organizations to consistently deliver sustainable business value, with increased agility and cost effectiveness, in line with changing business needs. However, in the context of a SOA approach, issues of semantic interoperability still remain unresolved while new challenges arise regarding web service interoperability. This paper presents a mediation framework which provides a uniform interface to the underlying HIS and is accessible via Android-enabled devices. The proposed framework is based on the agent paradigm for both healthcare process management and management of interactions among the participating systems. The healthcare processes and all interactions involved in each process are described according to the workflow metaphor.

The adoption of health information systems and the integration of healthcare data and systems into efficient cross-institutional collaboration workflows of stakeholders (e.g., medical providers such as physicians, hospitals, clinics, labs, etc.) is a challenging problem for the healthcare domain. This chapter studies the way that well-established software engineering concepts and architectural styles can be employed to satisfy requirements of the healthcare domain and ease health information exchange (HIE) between stakeholders. Towards this goal, this chapter proposes a hybrid HIE architecture (HHIEA) that leverages the studied styles that include service-oriented architecture, grid computing, publish/subscribe paradigm, and data warehousing to allow the health information systems of stakeholders to be integrated to facilitate collaboration among medical providers. To demonstrate the feasibility and utility of the HHIEA, a realistic regional healthcare scenario is introduced that illustrates the interactions of stakeholders across an integrated collection of health information systems.
