Added missing end of sentence in logic

[arminzavada]

Finished the end of the sentence:

In the Refinery web UI, ?exists(o) is represented with a dashed border, while ?equals(o, o)

to:

In the Refinery web UI, ?exists(o) is represented with a dashed border, while ?equals(o, o) is represented with a dashed line.

Hi,
As I read this line, I thought it was supposed to refer to the "shadow" effect appearing on some of the nodes, as seen on o in the model below:

class Thing.
Thing(t).
equals(t, t).
Thing(o).
?equals(o, o).

This "shadow" effect seems to be more specific to the exists relation, while the dashed arrow is the more "generic" representation for unknown connections. Note that the equals arrow does not appear with the default visualization filter settings.
