Name of the RDF graph.

options

(Reserved for future use.)

network_owner

Owner of the RDF network. (See Table 1-2.)

Usage Notes

This procedure deletes the RDF graph from the SEM_MODEL$ view, which is described in RDF Graphs.

This procedure is the only supported way to delete an RDF graph. Do not use SQL DELETE statements with the SEM_MODEL$ view.

Only the creator of the RDF graph can delete the graph.

To truncate an RDF graph instead of deleting it, use the SEM_APIS.TRUNCATE_RDF_GRAPH procedure.

For information about RDF network types and options, see RDF Networks.

Examples

The following example drops the RDF graph named articles.

EXECUTE SEM_APIS.DROP_RDF_GRAPH('articles');
