In the draft response to a comment: http://www.w3.org/2009/sparql/wiki/CommentResponse:PA-1 [[ Also, note that the actual syntax may still change, in fact, the group is discussing whether to take your proposal on board to allow '+' as a shortcut notation for string concatenation (fn:concat). ]] There are several choices for the operator, or it could be a keyword (in which case it can take a variable, but defined, number of arguments). CONCAT(?a,?b,?c) GROUP_CONCAT is related. Less need for a separator as it's a definite list of variables:. CONCAT(?a,",",?b,",",?c) ?a+","+?b+","+?c CONCAT("(",?a,",",?b,")") "("+?a+","+?b+")") Andy
