.. _CreateClassDialog:

Create Class Dialog
^^^^^^^^^^^^^^^^^^^

This dialog is opened whenever you try to create a new class, for example from the **Create Class** button on the
:ref:`ClassHierarchyPanel` or the **New** button on the :ref:`ClassListPanel`.

**Fields**

* **Label** will become the label (``rdfs:label``) of the new class.

* **ID** will be used as identifier (URI) of the class.

* **Description** will be used as ``rdfs:comment`` of the new class.

* **Superclass** is visible when no parent class has been selected before the dialog
   was opened, allowing you to pick a superclass.

.. important::
   Every class in your ontology should have at least one named superclass.
   Otherwise the class is hard to find in the class hierarchy and also unreachable by
   various other algorithms.

.. hint::
   The usual naming convention is to use upper-case names for classes but
   lower-case names for properties.

TopBraid will automatically make all newly created classes also (SHACL) node shapes.
This means that they can carry property declarations and other constraints later.
