Re: [Bigdata-developers] How to use RDR with Curl
|

Thanks a lot for the help.
But I dont know where I am still going wrong:
I inserted data using: curl -v -X POST --data-binary 'uri=file:///home/reifiedTriples.ttl' @tmp.xml http://192.168.145.1:9999/bigdata/sparql
And then queried it using: curl -X POST http://192.168.145.1:9999/bigdata/sparql --data-urlencode @tmp.xml 'query=SELECT * { <<?s ?p ?o>> ?p ?o }' -H 'Accept:application/rdr'curl: (6) Couldn't resolve host 'query=SELECT * <<'
Content-Type not recognized as RDF: application/x-www-form-urlencoded

Alice,
The workbench choice of the "in use" namespace is recorded in java script in your browser client. That choice does not effect other workbench clients and does not effect the behavior of the various endpoints when using command line tools to query or update data in the database. Thus your command line requests are being made against a namespace that is not configured for RDR support.
If you want to address a non-default bigdata namespace using curl or wget, you must use the appropriate URL for that namespace. This is all described on wiki.bigdata.com on the page for the nanoSparqlServer in the section on multi-tenancy.
See http://wiki.bigdata.com/wiki/index.php/NanoSparqlServer#Multi-Tenancy_API
Thanks,
Bryan

I found out an awesome feature in Bigdata called RDR and I am trying to explore that too. Can you please let me know as to where am I going wrong while querying RDR data (http://trac.bigdata.com/ticket/815). (My sample RDF data, contains reification in its standard form: http://www.w3.org/2001/sw/DataAccess/rq23/#queryReification)
