Hi all -
When I execute this query (taken verbatim from
http://www.w3.org/Submission/SPARQL-Update/):
"PREFIX dc: <http://purl.org/dc/elements/1.1/>
INSERT DATA INTO <http://example/bookStore>
{ <http://example/book3> dc:title \"Fundamentals of Compiler Design\" }
"
Unrelated: INTO not going to be strict SPARQL 1.1 Update:
INSERT DATA
{ GRAPH <http://example/bookStore>
{ <http://example/book3> dc:title "Fundamentals of Compiler Design" }
}
The update submission is superseded by SPARQL 1.1
I get a null pointer exception in this context:
0:

This happens whether or not I precede the query with this:
"CREATE GRAPH <http://example/bookstore>"
Here's a minimal pairing that works just fine:
"PREFIX dc: <http://purl.org/dc/elements/1.1/>
INSERT DATA
{ <http://example/book3> dc:title \"Fundamentals of Compiler Design\" }
"
Is there something else I need to do?
Versions: Jena 2.6.4, arq 2.8.8.
Eric,
I tried your example with ARQ 2.8.8:
java -cp 'lib/*' arq.update --dump --file ../../U.ru
where U.ru has:
-----------
PREFIX dc: <http://purl.org/dc/elements/1.1/>
INSERT DATA INTO <http://example/bookStore>
{ <http://example/book3> dc:title "Fundamentals of Compiler Design" }
-----------
java -cp 'lib/*' arq.update --version
==>
Jena: VERSION: 2.6.4
Jena: BUILD_DATE: 2010-12-12T16:56:15+0000
ARQ: VERSION: 2.8.8
ARQ: BUILD_DATE: 2011-04-21T10:12:50+0100
Might you have a second, old, copy of ARQ, on your system?
How are you invoking the operation/ Specifically, are you passing in a
model or a dataset, and are you using in-memory storage?
