Here's an example using our URIBurner instance (a public instance of Virtuoso with the Sponger and various Cartridges enabled): [1] http://linkeddata.uriburner.com/about/html/http/xapi.vocab.pub/datasets/adl/verbs/index.html -- Using /about service [2] http://linkeddata.uriburner.com/c/9DB7EM2T - Using /describe service . > > I am able to import my data when I use a RDF/XML file (.rdf) as the > graph URI, but I would really like to demonstrate that it can process > RDFa/HTML as an option. Thanks in advance. You should be able to use the /about service, as I have to achieve similar results. Once that works you simply enable the crawler to use the sponger. If you have any issues, share a screenshot of your crawler job configuration. Ensure you hatch the following checkboxes: [1] Run Sponger [2] Accept RDF -- this adds transparent content negotiation algorithm into the HTTP request [3] Store Metadata -- instruction to persist the sponger transformation to the designated named graph.
