Given the rapid uptake and the great diversity of PaaS offerings, understanding semantic interoperability at the PaaS level is essential for supporting inter-Cloud cooperation, seamless information exchange and application and data portability. In this vein, this paper introduces a PaaS semantic interoperability framework (PSIF). PSIF studies, models and(More)

Cloud computing is a promising IT paradigm which enables the Internet¢s evolution into a global market of collaborating services. Cloud computing semantic interoperability plays a key role in making this a reality. Towards this direction, a comprehensive and systematic survey of Cloud computing interoperability efforts by standardization groups,(More)
Cloud Platform as a Service (PaaS) is a novel, rapidly growing segment in the Cloud computing market. However, the diversity and heterogeneity of today's existing PaaS offerings raises several interoperability challenges. This introduces adoption barriers due to the lock-in issues that prevent the port-ability of data and applications from one PaaS to(More)
but they are still far from satisfying their constituents, as they usually operate inef-fi ciently and ineffectively. E-government and e-participation research aims to refo-cus government on its customers—citizens and businesses—and provide the models, technologies, and tools for more effective and effi cient public administration systems as well as more(More)
In this paper we define a formal model for a Public Administration service on the basis of the Web Service Mod-eling Ontology (WSMO). For this purpose we employ the generic public service object model of the Governance Enterprise Architecture (GEA) providing a PA domain specific semantics. We investigate conceptual mappings between PA entities and WSMO(More)
