I thought you might be interested in my experiences as a mini usability test. Despite the problems I ran into, I'm happy with the end result. #1: I am new to RDF visualization. So first I went to RDFViz and just hit the "Go!" button with the default options. I get a graphic. But it has no labels: * http://snowball.ilrt.bris.ac.uk/rdf-viz/out/rdfviz-2002-08-19:41-0-29.gif Then I try the SVG. My viewer complains about the namespace: * http://www.w3.org/Graphics/SVG/svg-19990412.dtd I guess GraphViz needs to be updated to the latest SVG version?? There is a link that says: "External RDF Services: Send your URI to W3C SiRPAC server instead." I don't know what it means by "External RDF Services" but I'm willing to give it a try. I click the button. I get back: "This form has been pre-loaded with data loaded from the URI supplied". Great! I hit "Send RDF to W3C SiRPAC Service." I get back a form that seems to have forgotten the RDF that the previous form had. Okay, fine, I go back and get the URI and paste it into the "Paste URI" field. This works nicely but it uses POST not GET so I don't get a nice GET-table URI which was my goal from the start. I want to be able to point people at a URI where all they have to do is hit a button or even better not even have to hit the button. #2: So I go back to the beginning and try some other data at rdfviz.org * http://www.oreillynet.com/meerkat/?_fl=rss10 I guess it can't parse that document. (it must not use a real XML parser???) * http://snowball.ilrt.bris.ac.uk/rdf-viz/out/rdfviz-2002-08-19:37-2-46.rtab Anyhow, once I gave up on a GET interface, I just resigned myself to cutting and pasting into the code text box and the SirPAC version works well. -- "When I walk on the floor for the final execution, I'll wear a denim suit.
