I'm sorry, the syntax { triple . triples . triples ... } is in use for
blank node formulas in some dialects.
SQL> TTLP ('<s> <p> { <s1> <p1> <o1> , <o2> } .', 'http://example.com/',
'http://example.com/');
SQL> sparql define output:format "NICE_TTL" with <http://example.com/>
construct where { ?s ?p ?o };
fmtaggret-NICE_TTL
LONG VARCHAR
_______________________________________________________________________________
@prefix ns0: <http://example.com/> .
@prefix ns1: <http://www.w3.org/2000/10/swap/reify#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
ns0:s
ns0:p [ ns1:statement [ rdf:type
rdf:Statement ;
rdf:object ns0:o1 ;
rdf:predicate ns0:p1 ;
rdf:subject ns0:s1
] ,
[ rdf:type
rdf:Statement ;
rdf:object ns0:o2 ;
rdf:predicate ns0:p1 ;
rdf:subject ns0:s1 ]
] .
ns0:s1
ns0:p1 ns0:o1 , ns0:o2 .
So I'd strongly insist on disambiguation keyword like
[ a :Patch;
:delete GRAPH { ... };
:inserts GRAPH { ... } ].
or something like that if the feature is ever introduced.
