You can add new predicates using the Add Predicate button on the top left corner. In the dialog box, you can add the name of the predicate, the type, language if required, and its indices.

You can add new Types using the Add Type button on the top left corner. In the dialog box, you can add the name of the Type and select which predicates belong to this Type. The list will show only existing predicates.

With this option you can edit the schema directly in plain-text. You also have the option to Drop the data.

Note There are two ways to drop the DB. The default option will drop the data but keep the Schema. To drop everything you have to select the check-box Also drop Schema and Types.
