18.4 SEM_RDFSA.REMOVE_OLS_POLICY

Format

SEM_RDFSA.REMOVE_OLS_POLICY(
     network_owner IN VARCHAR2 DEFAULT NULL,
     network_name  IN VARCHAR2 DEFAULT NULL);

Description

Permanently removes or detaches the OLS policy from the semantic data store.

Parameters

network_owner

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

network_name

Name of the semantic network. (See Table 1-2.)

Usage Notes

You should have the necessary privileges to administer OLS policies, and you should also have access to the OLS policy applied to RDF data. Once the OLS policy is detached from the semantic data store, all the sensitivity labels previously assigned to the triples and resources are lost.

This operation drops objects that are specifically created to maintain the RDF security policies.

To apply an OLS policy, use the SEM_RDFSA.APPLY_OLS_POLICY procedure.

For information about support for OLS, see Fine-Grained Access Control for RDF Data.

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

Examples

The following example removes the OLS policy that had been previously applied to the semantic data store.

begin
  sem_rdfsa.remove_ols_policy;
end;
