Open Schema Task

An Open Schema task is used to open a schema in a session without loading the associated data from that data store. This can be used if you just need to perform schema checks and want to avoid the unnecessary overhead of loading any data.

Note: Multiple Open Schema tasks can be used to bring in multiple schemas.

For each Open Schema task, a data store must be defined.

By default, an Open Schema task accesses all classes included in the Input Mapping (see Input Mapping). To override this, un-check the All Classes checkbox within the task, and select the required classes from the list that appears.

To use the Open schema task:

1. Navigate to the Sessions workspace.

2. From the Navigation Pane, select a session to edit.

3. Open the Tasks tab.

4. Click and select Open Schema.

5. In the Select Data Store dialogue that appears, select the data store to be used.

6. Click OK.

7. If you want all classes to be used, leave All Classes checked.
