dataset field: http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf

query:

prefix foaf:  <http://xmlns.com/foaf/0.1/> select ?name {     ?person foaf:name ?name . }

how specify dataset within query?

use from keyword:

prefix foaf:  <http://xmlns.com/foaf/0.1/> select ?name <http://dig.csail.mit.edu/2008/webdav/timbl/foaf.rdf> {     ?person foaf:name ?name . }
