Thanks to everyone for responding to my enquiry about making a SPARQL query from client-side JavaScript. I followed Aldo Bucchi's suggestion to look at the Virtuoso server documentation. I have built a tutorial webpage at http://projects.ischool.washington.edu/tabrooks/dbpedia/presentationPage.htm that illustrates the use of two mime types: JSON and text/html. I intend to use this tutorial with my undergraduate Informatics students this coming Autumn quarter. Receiving the payload from the Virtuoso server as text/html and then targeting the desired information with XPath is particularly easy and would be my recommended method. I was less successful in working with the mime type: 'application/sparql-results+xml'. While I could get client-side JavaScript to recognize the payload as XML, I wasn't able to target its contents with XPath. If anyone has an working example of unpacking a SPARQL XML object with XPath in client-side JavaScript, I would appreciate seeing it.
