    CubeViz.js: A Lightweight Framework for Discovering and Visualizing RDF Data Cubes
    (INFORMATIK 2017, 2017) Abicht, Konrad; Alkhouri, Georges; Arndt, Natanael; Meissner, Roy; Martin, Michael
    In this paper we present CubeViz.js, the successor of CubeViz, as an approach for lightweight visualization and exploration of statistical data using the RDF Data Cube vocabulary. In several use cases, such as the European Unions Open Data Portal, in which we deployed CubeViz, we were able to gather various requirements that eventually led to the decision of reimplementing CubeViz as JavaScript-only application. As part of this paper we showcase major functionalities of CubeViz.js and its improvements in comparison to the prior version.

    Discover Barrier-free Accessible Locations with the Location Navigator
    (INFORMATIK 2017, 2017) Abicht, Konrad; Ackermann, Simeon; Martin, Michael
    We present the current version of the Location Navigator, which supports users by finding locations in Leipzig, that can be accessed without barriers. Besides this current version of the prototype we present additionally experiences regarding its engineering process and the previously performed conversion of Open Data provided by the registered association Behindertenverband Leipzig e.V. (BVL). Our vision of the underlying data is an inter-commune data network, in order to support persons with special needs and, furthermore, to apply developments such as the Location Navigator to other municipalities. For this purpose, RDF will be used for the representation and linking of data in the future. Besides the presentation of the Location Navigator, we sketch some approaches we evaluated during the creation of the respective data model.
