redland librdf only provides syntax support for SPARQL Update, it does not
at present execute it, or as another way of saying it, let you load data.
The 'sparql11' query language name (or 'sparql' as of rasqal 0.9.28) really
means SPARQL 1.1 Query.

Redstore http://www.aelius.com/njh/redstore/ which is based on redland
provides a service (daemon) including sparql protocol and sparql update.
