This paper describes a service-oriented architecture for accessing resources through semantically designed portals called hubs. The services are dedicated to: (a) ontology management, (b) annotation generation from texts based on linguistic or machine learning techniques, (c) persistent storage of ontologies and metadata, and (d) semantic search in(More)
We present a new provenance model for generating <i>fine-grained</i> data and service dependencies within XML data processing workflows. Our approach follows the widely used <i>black box transformation</i> semantics [15] in which service components produce new outputs from their inputs (without transformation). The heart of the model are <i>data dependency(More)
■ RÉSUMÉ • Plusieurs écoles tentent d'innover dans un contexte où le paysage technologique évolue rapidement et les tablettes numériques telles l'iPad sont clairement identifiées comme une technologie émergente susceptible d'avoir des retombées importantes en éducation à très court terme (Johnson et al., 2012). Une école secondaire québécoise intègre depuis(More)
We describe the WebContent platform for the management of content from the Web. The platform is based on a service-oriented architecture and Web standards (notably, Web services, XML and RDF). An enterprise service bus (following the JBI specification) and BEPL may be used to orchestrate service invocations. A peer-to-peer architecture may also be used to(More)
WePIGE illustrates a new approach for extracting fine-grain-ed provenance information from XML artefact-based work-flow executions. The extraction framework relies on the usage of XPath mapping rules for inferring data and service dependency links [2]. This demonstration illustrates the usage of the WePIGE graphical user interface for exploring the(More)
