Footnote 1. To import data into the local store, a set of different possibilities are offered. Besides common RDF serializations like Turtle, N3 or JSON-LD, balloon Synopsis offers to specify a SPARQL endpoint and SPARQL query to load remote RDF data portions. In the whole project, cross domain problems are circumvented by using YQLFootnote 2, to facilitate remote data querying. The initial view can be configured by an arbitrary initialization query to the local store or an automatic arrangement of all entities.
Balloon Synopsis is developed on a modular basis and available as free open source software to support contributions and extensions. Further developments will focus on the collection of ontology templates to continuously enhance the visualizations. A first demonstration as well as the prototypic sources are available at http://schlegel.github.io/balloon/balloon-synopsis.html.
