Modeling visualization tools and applications on the Web
Ghislain Auguste Atemezing, Raphaël Troncy · 2014
Publishing data on the Web is getting more and more adoption within the umbrella of Open Data. Governments and local authorities are giving access to their data free of charge, although sometimes in heterogeneous formats. Linked Data prin- ciples enables the use of common model to make things interlinked on the Web. While this is true for publishers, consumers are involved in this loop of publication by building visualizations using (re)-existing tools from the information visualization community (InfoVis). However, there is a need to describe applications built with those tools in order to easily discover ap- plications on the Web. Besides, Open Data events usually contain application contests helping to showcase the usefulness of data, without structured data available in the web-pages. The contribution of this paper is three-fold. First, a review of tools for creating applications is provided, with a classification based on domains. Second, the DVIA vocabulary is proposed to annotate applications with a common semantics. Third, a design and implementation of a universal plugin to generate RDF data from application contests is described in detail.
