Here is a word about the view panel you see at the top left. The button near the top below OPM, with a central dot connected to three other dots is for showing the directed graph shown in the center. The button below, with three dots aligned on the left is for showing the list documents returned.

We can also select the fresnel button near the bottom of the view panel. This allows us to eliminate parts of triples, to simplify views such as the directed graph.

s3) (EISPP_3_M_Fernandez_NLQ_2fresnel_GSS)

In addition, selecting the GSS, or graph stylesheets button, allows us to apply color or other styles to the graph to aid interpretation.

For reference, graph stylesheets come from IsaViz and Fresnel lenses come from a paper by Christian Bizer et al. Further information is provided below the video.

In the future, we may want to consider using more of the Fresnel technology by considering the formating capabilities of Fresnel formats with CSS instead of GSS.

Another thing we can do is click the list button to remove the list.
