Hi, Andy,
For query, we have:
String queryUri = "http://xxx.ccc.com:3030/dataset/query";;
Query query = QueryFactory.create(queryString);
QueryEngineHTTP qeHttp = QueryExecutionFactory.createServiceRequest(queryUri,
query);
ResultSet results = qeHttp.execSelect();
which is perfect.
How about for update?
Do we also have similar things like:
String updateUri = "http://xxx.ccc.com:3030/dataset/update";;
UpdateRequest ur = UpdateFactory.create(updateString);
And then get the handle to execute update? It'd be great if you can come up
with some code examples.
UpdateExecutionFactory.createRemote.
Javadoc:
http://jena.apache.org/documentation/javadoc/arq/com/hp/hpl/jena/update/UpdateExecutionFactory.html#createRemote%28com.hp.hpl.jena.update.UpdateRequest,%20java.lang.String%29
The project would be delighted to receive additional content for the web
site. The content is in svn:
https://svn.apache.org/repos/asf/jena/site/trunk/
Andy
Thanks
Frank

Thanks for that, Andy.
So, we can't use any existing API (for we've already grabbed the handle of the
namedGraph model) to duplicate it, SPARQL/update is the only way to do it.
Mu suggestions were made so as to avoid copying everything onto the
local machine, and copying it back out again. Using COPY, only a copy
within the remote machine is done. Is that what you are trying to do?

Hi, Andy,
What will be better way to duplicate existing named graph remotely?
Or duplicated many with different URIs. Is there any simple API to
use for it? Thanks.
Cheers Frank
SPARQL Update:
something like
COPY <g1> To <g2>
for a one to one copy:
or
INSERT { GRAPH <g> { ?s ?p ?o } }
WHERE { GRAPH ?g { ?s ?p ?o } FILTER ( ?g IN ( <g1>, <g2>, <g3> ) ) }
for many
(untested)
