SPARQL federated queries can be affected by both characteristics of the query and datasets in the federation. We present SILURIAN a Sparql visualizer for understanding queries and federations. SILURIAN visualizes SPARQL queries and, thus, it allows the analysis and understanding of a query complexity with respect to relevant endpoints and shapes of the possible plans.

As any High Energy Physics experiment evolves, the understanding and requirements for the data objects that need to be stored will change. This paper discusses the criteria to which these changes must conform so that physicists can continue to run their analysis programs and how these criteria are satisfied in BaBar’s Objectivity Federations. The Objectivity product has a native system for mana...

We discuss the impact of locally implemented behaviour on global behaviour specification in a federation of object-oriented databases. In particular, given a specification of an integrated view of a number of component databases, we discuss the process of determining the global methods that are implicitly implemented by a given set of local methods on these component databases. To this end, we ...

Research about software processes modelling and support, even during the last decade, has suffered from a lack of practical credibility. Most of the solutions proposed have not gained wide acceptance by the software industry and, moreover, some fundamental issues like evolution have not yet found any reasonable solution. For these reasons, it was a clear decision in the PIE project to build a p...

The story of the European Federation of Medical Informatics (EFMI) can be looked upon as one of the followers from the early days of the development of Societies and federations for persons interested in Information Technology and in cooperation and exchange of information and technology, not only in countries but also between countries.

This essay examines the policy response of federal and regional governments in federations to COVID-19 crisis. We theorize that is an outcome strategic interaction among incumbents shadow their varying accountability for health repercussions from disruptive consequences public measures.
