Catch DELETE/INSERT DATA queries that include non-ground triples

[mterdjimi]

Hello,

As from the SPARQL 1.1 specification, DELETE/INSERT DATA queries only allow ground triples. However, the following (incorrect) query does not return any parsing error :

DELETE DATA { ?s ?p ?o }

Best,

Mehdi

Interesting, this is not specified in the grammar.

The SPARQL 1.1 Update specification indeed mentions that triples need to be ground. I also noted an exception on blank nodes.

Indeed, both QuadPattern and QuadData refer to Quads in the grammar.

Noticed this issue since I'm going through UPDATE stuff myself.

This actually is specified in the grammar, it's note 8 in the notes above the grammar table. The exception on blank nodes is note 10 (which links to the section you linked).
