Hello, The docs at http://jena.apache.org/documentation/query/negation.html
Say that "UNSAIDis an alias for NOT EXISTS" I wasn't familiar with that keyword so gave it a try at sparql.org and got: Error 400: Parse error: # Names of people who have not stated that they know anyone PREFIX foaf: <http://xmlns.com/foaf/0.1/> SELECT ?name WHERE { ?x foaf:givenName ?name . UNSAID { ?x foaf:knows ?who } } Lexical error at line 5, column 11. Encountered: " " (32), after : "UNSAID" Fuseki - version 1.0.0 (Build date: 2013-09-12T10:49:49+0100) Is this a documentation bug? Thanks, Tim
