This function tries to modify either the target graph specified in the patch via guo:target_graph (hence, the non-NULL target_graph argument of the diff creator, DB.DBA.RDF_SUO_DIFF_TTL() ) or the graph specified by default_target_graph argument. The function returns zero in case of success, non-zero value otherwise. In addition, the function produces a result set that describes the process of matching blank node in the target graph to instructions in the patch.
The TURTLE made by DB.DBA.RDF_GRAPH_DIFF can be loaded later into an empty graph and the IRI_ID of that graph can be passed as the first argument to this patch function.
