Modify > Add property shapes from Wikidata sample
"""""""""""""""""""""""""""""""""""""""""""""""""

This feature is available from the :ref:`ModifyMenu` for classes and node shapes within Ontology asset collections.
It opens a dialog where you can enter the ID of a Wikidata entity, and the system can suggest property definitions
based on the values of the property that are actually used at the entity.

.. hint::
   Wikidata has a different class/instance system than traditional RDF-based ontologies.
   Entities often use properties at hoc even if they are undeclared, and most entities do not
   rely on the ``rdf:type`` property like normal RDF instances do.
   For these reasons it is often necessary to create intermediate RDF and SHACL friendly
   classes with property declarations that make browsing and using Wikidata instances easier.

More information on working with Wikidata can be found in the further reading below.
