owlready2_cheatsheet

This is a set of functions that I have been using to process an owl graph. Given base name and folder path, it loads and parse a local rdf/xml file and prints some of its content (object properties, individuals, etc).

The code contains the following functions:

1. create_class_by_name Create a class given a name
2. get_classes Get all classes
3. has_object_properties Check if instance has object properties
4. is_domain_or_range Returns true if item is domain or range individual.
5. get_object_properties Get all the object properties of the ontology
6. get_data_properties Get all the data properties of the ontology
7. check_instance Find an instance by string name
8. get_instance_classes Get classes of an instance
9. get_class_by_name Get a class by its string name
10. attach_instance_to_class Attach an instance to a class
11. get_individuals Get all the individuals in the ontology
12. add_data_property Add one or more values as data properties of a specific type to an instance
13. get_uri Create a uri given the base name and class name
14. create_instance_of_class Create an instance of a class
15. remove_superclasses Remove the superclasses of a given class if they are superclasses of a given super class (if we'd want to attach the given class to the given superclass)
16. attach_class_to_subclass Given a class name and that class super class name, and a sub class, assign the super class of that subclass, creating it if necessary. There can be more than one super class to assign (csv string).
17. attach_class_to_superclassSame as ```attach_class_to_subclass`` but for subclass,
18. get_class Given a class name and its super class name, we create that new class if it does not exist or we return the existing one
19. add_object_property Given an instance (domain) and an object property, assign another instance by name as range of the domain instance object property. There can be more than one (comma separated).
20. is_instance_of_class Returns True if the instance is of the class name. If descendants input argument is set to True then it looks for the subclasses too.
