Data Governance and Federation in large complex organizations poses non-trivial challenges due to the integration of heterogeneous, distributed data sources. Semantic Web, and its de-facto standard query language — SPARQL — have proven to be key in defining and searching semantic over any sort of content on the Web, thus easily letting content clients discover hidden relationships among disparate...
Cloud now provides a wide range of services hosted by different providers from different domains. These services can be composed together dynamically to realize important tasks. In a composite service, information may flow from one service to subsequent services from different domains. Such information flow, if not properly controlled, may cause undesired leakage of critical data. Existing works on...
Geospatial information is a common resource used at personal and corporative levels for decision making. Nowadays, a relevant percentage of the geospatial data on the web is provided by standardized services. However, due to the deficiencies in the service content descriptions, the data required for a task are not easy to find. To improve the description of geospatial information on the Web, this...
The rapid changes of information technology led to the proliferation of Web-based Information Systems (WIS). There has been already some research on the general model for analysis and design of WIS. This paper attempts to define a comprehensive framework for integrating the various viewpoints of model for WIS. Several components that compose of a WIS as analyzing and designing element are investigated...
In industrial settings, products are rarely developed by one organization alone. Software vendors and suppliers typically maintain their own product lines, which can contribute to a larger (multi) product line. The teams involved often use different approaches and tools to manage the variability of their systems. It is unrealistic to assume that all participating units can use a standardized and prescribed...
The interoperability of the data sharing across different organizations is key for the efficient management of large-scale incidents. The system introduced in this paper will provide multi-disciplinary rescue teams with an integrated and intelligent communication and information system for efficient data sharing and emergency process management before, during and after major incidents. The project...
A major issue in the resource allocation problem, also known as the data and service allocation problem, in a networked organization is the key problem in Web services distribution. A detailed investigation is carried out of the resource allocation model of allocating data and application services across a distributed networking system. The data and application service allocation problem is modeled...
Presently, distributed data integration is a hot issue of distributed computing. With the development of Web services, many researches begin to use Web services for data integration. In this paper, a distributed data integration framework based on Web services and Lightweight Directory Access Protocol is described. Using Web Services, the distributed and heterogeneous data resources are encapsulated...
Nowadays, there are increasing amount of data fields of tide and tidal current gained from ocean dynamical environment real-time stereo monitoring platform, model calculation and numerical simulation. Collaborative visualization of these data fields on the internet is becoming increasingly important for the utility of data. In this paper, we summarize the characters of tide and tidal current data...
Service-oriented systems facilitate business workflows to span multiple organizations (e.g. by means of Web services). As a side effect, data may be more easily transferred over organizational boundaries. Thus, privacy issues arise. At the same time, there are personal, business and legal requirements for protecting privacy and IPR and allowing customers to request information about how and by whom...
How to share the data in databases of autonomous organizations quickly and flexibly is an important problem. Traditional data integration systems are supposed to be a solution to the problem. Unfortunately, they require a global schema before they can be used to share data and they are centralized system. They can not support data sharing without a common schema and on-demand data sharing in applications...
The model presented in this paper is the main result of an on-going national science foundation project of China, called emergency-driven virtual organization (EDVO), which aims at building and developing an innovative software infrastructure (software, models, services, etc.) for supporting collaborative work of events handling in emergency/disaster scenarios. In such scenarios, different government's...
Several vulnerability analysis techniques in web-based applications detect and report on different types of vulnerabilities. However, no single technique provides a generic technology-independent handling of Web-based vulnerabilities. In this paper we present our experience with and experimental exemplification of using the application vulnerability description language (AVDL) to realize a unified...
Process modeling and rule modeling languages are both used to document organizational policies and procedures. However, little work has been done to understand their synergies and overlap. Understanding the relationship between the two modeling types would allow organizations to maximize synergies and reduce their modeling effort. In this paper we use the well-established Bunge-Wand-Weber (BWW) representation...
Accelerated by the rapid deployment of distributed systems and the Internet, online collaboration and information sharing are pervasive in enterprise computing environment. With regard to the requirements of online collaboration and information sharing, authentication information needs flexible manipulation to facilitate federation across trust domains. To achieve identity federation for federated...
In recent years, organizations have been shifting focus to their core business competencies, and reducing total cost of ownership (TCO) associated with training and management of their IT infrastructure. In the same motif, organizations are establishing security and survivability frameworks as an integral part of their business strategy so as to provide an acceptable quality-of-service for their clients...
