Paggr: Linked Data widgets and dashboards

The Linked Data effort has led to a large number of interconnected and reusable datasets with standardized RDF interfaces. Paggr is a novel Web system that simplifies personalized aggregation and interaction with these structured information sources through SPARQL-driven widgets and dashboards. Paggr utilizes a URI-based drag and drop mechanism for end-users, and a collaborative, browser-based development environment for widget creators.
