In the case where no RDF data can be retrieved (as opposed to the empty graph being retrieved)
from the IRI denoted by <em>IRIref_from</em>, or in case the retrieval method returns an
error (such as, for instance an HTTP error code), the SPARQL 1.2 Update service SHOULD
return failure and the status of the Graph Store SHOULD remain in the same status as
prior to the request; in case the keyword `SILENT` is present, however, the
operation will still return success and the status of the Graph Store is not specified
by the present document: implementations may create the destination graph or not and
partially load data, in case of a transmission error where partial data has been
received (which itself may be legal RDF).

failure and the status of the Graph Store SHOULD remain in the same status as prior to
the request. However, if the the keyword `SILENT` is present, operation will return
success, rather than failure, and the status of the Graph Store is is not specified.
