History Of

In general, provenance describes the origin and well-documented history of a given object. This notion has been applied in information systems, mainly to provide data provenance of scientific workflows. Similar to this, provenance in Service-oriented Computing has also focused on data provenance. However, the authors argue that in service-centric systems the origin and history of services is equally important. This paper presents an approach that addresses service provenance. The authors show how service provenance information can be collected and retrieved, and how security mechanisms guarantee integrity and access to this information, while also providing user-specific views on provenance. Finally, the paper gives a performance evaluation of the authors’ approach, which has been integrated into the VRESCo Web service runtime environment.

Rich Data

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.

Operation Center

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.

Is Projects

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.

Geospatial Web Services

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.
