Format

SEM_APIS.ENABLE_CHANGE_TRACKING(
     models_in     IN SEM_MODELS,
     network_owner IN VARCHAR2 DEFAULT NULL,
     network_name  IN VARCHAR2 DEFAULT NULL);

Description

Enables change tracking for a specified set of models.

Parameters

models_in

One or more model names. Its data type is SEM_MODELS, which has the following definition: TABLE OF VARCHAR2(25)

network_owner

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

network_name

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

Usage Notes

Change tracking must be enabled on a model before incremental inference can be enabled on any entailments that use the model.

To use this procedure, you must be the owner of the specified model or models.

If the owner of an entailment is also an owner of any underlying models, then enabling incremental inference on the entailment (by calling the SEM_APIS.ENABLE_INC_INFERENCE procedure) automatically enables change tracking on those models owned by that user.

To disable change tracking for a set of models, use the SEM_APIS.DISABLE_CHANGE_TRACKING procedure.

For an explanation of incremental inference, including usage information, see Performing Incremental Inference.

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

Examples

The following example enables change tracking for the family model.

EXECUTE sem_apis.enable_change_tracking(sem_models('family'));
