3. For Mapping Type, you can specify Table or View mappings, and enter a Display Name. Choose the Data Source, Schema, Table Name, and Column.
4. In most cases, it is best to automatically generate an IRI template, which will generate a unique identifier that corresponds to the unique keys in the chosen Column. Choose a Concept Template from the drop-down.
5. To test the IRI template, click Test. The results will appear in the RDF field.
6. Click the Create button to add the mapping to the document.
