Playing around with the doghouse I notice when I try to browse the
vertices of sailgraph in the default settings I get "Error: Could not
get the vertices of graphs from Rexster." and this URL
http://localhost:8182/sailgraph/vertices?rexster.offset.start=0&rexster.offset.end=10
gives back a 500 Error -- is this because RDF has no vertices, but
rather is all edges?
is this something that would be better reported as a github issue?
