Draft reply to: AD-1


Thank you for your comments on BINDINGS.

The working group has reworked what was previously BINDINGS with a new VALUES clause that can be used for inline data at any point in the graph pattern where a pattern group element can be given. The details are in the editors' working draft [1] and the grammar.

The syntax is a little different from BINDINGS to make the one variable/several variables cases a little clearer as this is the emerging use for VALUES, not it's original motivation from federated query.


     VALUES ?x { :x1 :x2 }
     ?x rdfs:label ?label .
    VALUES (?dayIDCheck ?dayName) {
    (0 "Sunday"@en)
    (1 "Monday"@en)
    (2 "Tuesday"@en)
    (3 "Wednesday"@en)
    (4 "Thursday"@en)
    (5 "Friday"@en)
    (6 "Saturday"@en) }
    BIND (0 AS ?dayID)
    FILTER (?dayIDCheck = ?dayID)

VALUES can be used where BINDINGSs was allowed but also multiple VALUES clauses are allowed within the graph pattern and will cause a join of each table of inline data with the query pattern matching. VALUES clauses are allowed on sub-queries.

We would be grateful if you would acknowledge that your comments have been answered by sending a reply to this mailing list.
