Upload a reliably large RDF file to openrdf Sesame Ontology Manager

Question

I need to upload a very large ontology, presented as an N-triples (1gb) file, to the openrdf Sesame application. For this, I use the workbench interface. I know that this file is too large to load in a single request. To get around this, I split my files into 100 MB files. But I still get the error message from openrdf Sesame server:

HTTP ERROR 500

Problem accessing /openrdf-workbench/repositories/business/add. Reason:

    Unbuffered entity enclosing request can not be repeated.
Caused by:

org.apache.commons.httpclient.ProtocolException: Unbuffered entity enclosing request can not be repeated.
 at org.apache.commons.httpclient.methods.EntityEnclosingMethod.writeRequestBody(EntityEnclosingMethod.java:487)

Does anyone have a good knowledge of openrdf Sesame or another ontology manager that I could use for my task?

Thanks so much for your input.

TO.

I don’t know exactly what task you want to achieve, but you can check here for a list of scalable three stores with informal (mostly self-advertising) scalability results. In this case, Sesame only reports that it processes 70M applications (not so much ... could be the cause of your problems.)
