Scientific repositories found in institutions and organizations consist of data and programs. Data consists principally of numeric data, images, and text documents. Programs consist principally of software methods for visualizing and processing data and simulators of natural processes. Data represents both measured physical behavior and the results of(More)
The ARION system provides basic e-services of search and retrieval of objects in scientific collections, such as datasets, simulation models and tools necessary for statistical and/or visualization processing. These collections may represent application software of scientific areas, they reside in geographically disperse organizations and constitute the(More)
In this paper, we present an integrated system architecture for metacomputing on top of distributed scientific resources via active semantic-driven information management. Our approach is to consider both data and programs as objects of an application-specific ontology, describing them via corresponding metadata schemata that can be exploited to search for(More)
The Internet of Things (IoT) vision involves a future Internet integrated with real-world objects that can commonly offer their functionality trough services. In such pervasive environments of IoT networks, locating and invoking suitable services is quite challenging and traditional service discovery and selection approaches have been proven inadequate. In(More)
