A web application for exploring a knowledge graph.
The purpose of this webapp is (i) to provide an early demonstration of the widgets created in D3.1 and (ii) provide a useful tool for exploring a knowledge graph.
For the early demonstration, we use a description of experimental datasets for physical metallurgy produced in the Norwegian SFI PhysMet project.
The figure below shows how each experimental dataset in the knowledge graph is defined and how it relates to other resources.

Figure The interrelations between the sample, dataset and measurement (blue boxes) and their relation to shared resources (red boxes).
Accessibility is provided via the dataset distribution (gray box), which is a blank node exposing a dcat:downloadURL or dcat:accessURL.
Literals relations are not shown for brevity.
