Have you tried this utility yet?

I just added a utility to do this operation, here's an example:
VerboseQuadStore myStore = ...
Context contextToRename = new Context( "http://whatever.org/my-context";
);
Context newValue = new Context( "http://whatever.org/the-new-value"; );
new RdfStoreTools( myStore ).renameContext(
When I think about it it should be a simple and fast operation to do that,
i.e. change the value of only one node and reindex it. Unfortunately there's
nu tool for such an operation, but I can see what I can do to create such a
tool for you. Allright?

Do you mean change the URI of a context node (since each context is
represented by a node) so that all statements within that context gets the
new value automatically?
Or do you mean something else? It'd be helpful if you could to be more
specific.

Hello,
Is it possible to update the context value in verbose triple store ?
Thank you, Luda

Hi,
I have sort of architectural question.
I am thinking about how to construct triple store based on
verbosequadstore of neo4j.
The problem that I am going to have too many contexts (I want to model
version as context), and I think the verbose quad store attaching context
to the reference node.

Hi Mattias,
I tried the DenseTripleStore as well but that crashes (see below for the
stacktrace).
All this is for version org="org.neo4j" name="neo-rdf-sail"
rev="0.5-SNAPSHOT" (I use Ivy).
The DenseTripleStore wouldn't help me anyway as I need named graph
support and reading the wiki, it wou
Hi Andy,
Great to hear you trying out neo4j and the neo-rdf-sail component.
We're aware that the bulk-insert performance isn't what it should be
and some of the performance caveats is in the neo-rdf-sail component,
which is a layer around the neo-rdf component. So if you could try to
go directly t
I'm trying to get neo-rdf-sail to run through the Berlin SPARQL
Benchmark [1].
It's taking about 21 mins to load 1e6 triples for data and 115 mins for
5 million triples. This is a bit slow - projecting from that, 100M is
at least 30 hours.
