persuant to ACTION: ericP to draft text about a LOOSE keyword and run it by w3 folks to see if we're abusing the "at risk" mechanism. I drafted this section. It was slightly more awkward to not have an ALL to lean on, but I think this is pretty well defined: 9.4 INDISTINCT While the DISTINCT modifier ensures that duplicate solutions are eliminated from the solution set, INDISTINCT simply permits them to be eliminated. The cardinality of any set of variable bindings (solution) in an INDISTINCT solution set at least one and not more than the cardinality of the solution set with no DISTINCT or INDISTINCT modifier. For example, the query PREFIX foaf: <http://xmlns.com/foaf/0.1/> SELECT INDISTINCT ?name WHERE { ?x foaf:name ?name } may have one, two (shown here) or three solutions: name "Alice" "Alice" -- -eric office: +1.617.258.5741 NE43-344, MIT, Cambridge, MA 02144 USA (eric@w3.org) Feel free to forward this message to any list for any purpose other than email address distribution.
