Hi Jon, What is the version of the Virtuoso Server you are attempting to run your query against as the query you provide runs successfully for me, returning one row, against one of our demo server:
http://demo.openlinksw.com/sparql?default-graph-uri=&query=PREFIX+foaf%3A+%3Chttp%3A%2F%2Fxmlns.com%2Ffoaf%2F0.1%2F%3E%0D%0APREFIX+skos%3A%3Chttp%3A%2F%2Fwww.w3.org%2F2004%2F02%2Fskos%2Fcore%23%3E%0D%0ASELECT+%3Fs%0D%0AWHERE+%7B%0D%0ASERVICE+%3Chttp%3A%2F%2Fpoolparty.reegle.info%2FPoolParty%2Fsparql%2Fglossary%3E%7B%0D%0A+%3Fs+foaf%3Apage+%3Chttp%3A%2F%2Fen.wikipedia.org%2Fwiki%2FFuel_cell%3E+.%0D%0A+%3Fs+skos%3Adefinition+%3Fv+.%0D%0A%7D%0D%0A%7D&should-sponge=&format=text%2Fhtml&CXML_redir_for_subjs=121&CXML_redir_for_hrefs=&timeout=0&debug=on

So I assume you are running a Virtuoso version before full SPARQL-FED support
was available. I would recommend you upgrade to the latest 6.1.4 open source
release available from:
