SPARQL 1.1 Update

[Sorin Gheorghiu]

Hi,

while attempting to remove some triples, I noticed that VALUES is not
supported, here an example:

DELETE WHERE {
VALUES (?value) { ( '10' ) ( '20' ) ( '30' ) }
?s ?p ?o .
?s _:prop ?value .
}

although SELECT works with multiple values:

SELECT * WHERE {
VALUES (?value) { ( '10' ) ( '20' ) ( '30' ) }
?s ?p ?o .
?s _:prop ?value .
}

I would assume VALUES is not supported by SPARQL 1.1, but at least
DELETE using the |IN| function in a |FILTER| clause should be supported
according to example 6 from
https://www.w3.org/TR/2013/REC-sparql11-update-20130321/

DELETE WHERE {
?s ?p ?o .
?s _:prop ?value .
FILTER(?value IN("10","20","30"))
}

Sorin

DELETE WHERE is a shorthand for the full form of DELETE:

DELETE { X } WHERE { X }

which places restrictions on X to be a template for the first { X }.
Templates (c.f. CONSTRUCT) does not allow VALUES.


DELETE {
VALUES (?value) { ( '10' ) ( '20' ) ( '30' ) }
?s ?p ?o .
?s _:prop ?value .
}
WHERE {
?s ?p ?o .
?s _:prop ?value .
}

DELETE WHERE {
?s ?p ?o .
?s _:prop '10' , '20' , '30 .
}

because it is a single variable VALUES.

FILTER(?value IN("10","20","30"))
}

Example 6 is:

DELETE
{ ?book ?p ?v }
WHERE
{ ?book dc:date ?date .
FILTER ( ?date > "1970-01-01T00:00:00-02:00"^^xsd:dateTime )
?book ?p ?v
}

which is the full form.

Oh - and _:prop (a blank node as property) is not legal either. It gets
weird otherwise ...

Hi Andy,

Following your answer, I succeeded to delete the whole tuples using:

DELETE {?s ?p ?o] WHERE
?s ?p ?o .
?s rdf:id ?value .
FILTER (?value IN ( { ( '10' ) ( '20' ) ( '30' ) }
}

The initial question wasn't related to blank nodes, I used a wrong dummy
_:prop

Thank you,
Sorin

I don't think there is an rdf:id property? You haven't provided the
namespace for it, but you shouldn't be introducing your own terms in
the RDF namespace.
