The Internet-of-Things (IoT) is unanimously identified as one of the main pillars of future smart scenarios. However, despite the growing number of IoT deployments, the majority of IoT applications tend to be self-contained, thereby forming vertical silos. Indeed, the ability to combine and synthesize data streams and services from diverse IoT platforms and testbeds, holds the promise to increase...
This paper analyzes the potential of Semantic Web technologies to support innovation in industrial scenarios. The study focuses in particular on RDF stores, the software components dedicated to the storage, representation and retrieval of semantic information. Starting from a literature review, a qualitative analysis is carried out considering a set of these systems. RDF stores are evaluated to find...
Smart Grids are trending towards integrating Industrial Control Systems (ICS) and other domain systems for efficient operational and maintenance activities and cost savings. However, this integration poses the challenge of modeling information in a multi technology domain such that process data (e.g. voltages) and non-process data (e.g. physical access) are exchanged in an interoperable way. This...
Reconfigurable Radio Systems (RRS), based on Software Defined Radio (SDR) and Mobile Ad-hoc Network (MANET) technologies, offer considerable advantages for military operations, such as increased network survivability and interoperability. The RRS-based Common Tactical Radio System (GTRS), currently in development by the Swedish Armed Forces, is designed for use in diverse geographical settings and...
This contribution focuses on interoperability in the overall context of Smart Grids. Whereas Smart Grids are understood as the future energy supply system supported by ICT. For the upcoming need for massive data exchange in Smart Grids both syntactic and semantic issues have to be addressed. In terms of data exchange and ICT semantics are covered by electronic data models representing the real world...
The financial services industry presents some unique challenges in data integration, both within firms and across the securities trading process. This paper describes how the industry came to an awareness of the need to define semantics as an industry wide standard, and the methods and processes used to realize that requirement in the form of an industry Semantics Repository. The repository is described...
Aiming at satisfying the urgent requirement of interoperability in education information systems, and based on the research of CELTS_40, this article put forward a new interoperability multi-tier EMIS architecture model, which can implement most of the functions defined in CELTS_40 and some of new unique functions. In addition, it also overcomes the shortcomings of traditional EMIS systems effectively,...
The number and size of different kinds of electronic files (text, pictures and videos) incorporated into eLearning environments were dramatically increased during the last ten years and this triggered a development of new web based systems for that specific environment. These systems were developed to satisfy current and specific users' needs which lead to appearance of very heterogeneous environments...
This paper discusses the challenges faced by large engineering firms in organizing and analyzing vast amounts of diverse geospatial data to support complex engineering projects worldwide. For Bechtel, the implementation of an enterprise GIS has greatly facilitated spatial data sharing and utilization, but has required much forethought and planning in the architectural design, standards and tools required...
Interest in service oriented architecture (SOA) is rapidly increasing in the business world due to the many benefits it offers such as reliability, manageability, reusability, flexibility, efficiency, and interoperability. There are many security technologies and models being developed for SOA. They implement or encode specific aspects of authentication, authorization, encryption, trust, and access...
The definition of advanced and distributed management frameworks is one of the key research issues that still need to be addressed in the network and service management research field. As part of this effort, the use of Web service technologies provides some advanced features such as improved interoperability and flexibility. This paper describes the main requirements and key components of a Web service-based...
An operational definition for role-based access control (RBAC) is that permission assignment is based on the role a principal is assuming during a work session. The central underlying concept is thus that IT permissions are assigned to roles rather than directly to users. This level of indirection can provide simpler security administration and finer-grained access control policies.
The healthcare system in Denmark is well known for its high level of IT support and interoperability. The Danish healthcare system integrates several central technological solutions across hospital information and electronic medical record systems throughout Denmark. Important business drivers for this high level of interoperability include unique citizen ID numbers and a publicly funded healthcare...
