Hello

Welcomen first make sure you read http://docs.sparnatural.eu/hello-sparnatural/Hello-Sparnatural.html and http://docs.sparnatural.eu/how-to-configure/How-to-configure-Sparnatural.html

2 ways to do what you want:

  1. Add "Building" in your config, so that you will have both Location and Building to select from
  2. See https://github.com/sparna-git/Sparnatural/issues/494 . You can use a TreeProperty with the datasources datasources:tree_children_subClassOf and datasources:tree_root_domain_subClassOf

Also, we are thinking about improving the class selection to make it with 2-levels hierarchy : #351 (in 2024 probably)
