The KnowledgeOntology class loads the ontology from a YAML file and provides methods to access its components.

​
__init__(self, ontology_file: str)

Initializes a new instance of the KnowledgeOntology class. 
from a1facts.ontology import KnowledgeOntology

ontology = KnowledgeOntology(ontology_file="ontology.yaml")
Parameters:
  • ontology_file (str): The path to the YAML file defining the ontology.

​
find_entity_class(self, name: str)

Finds an entity class by name. 
company_class = ontology.find_entity_class("Company")
Parameters:
  • name (str): The name of the entity class to find.
Returns:
  • An EntityClass object or None if not found.

​
get_add_or_update_tools(self, add_entity_func, add_relationship_func)

Gets a combined list of all add/update tools for both entities and relationships. These tools are used by agents to modify the knowledge graph. 
# These functions would typically be methods of the KnowledgeGraph class
def add_entity(entity_data):
    pass

def add_relationship(relationship_data):
    pass

tools = ontology.get_add_or_update_tools(add_entity, add_relationship)
Parameters:
  • add_entity_func (function): The function to call to add/update an entity.
  • add_relationship_func (function): The function to call to add/update a relationship.
Returns:
  • A list of all add/update tool functions.

​
get_get_tools(self, get_all_entity_func, get_entity_properties_func, get_relationship_properties_func, get_relationship_entities_func)

Gets a combined list of all “get” tools for both entities and relationships. These tools are used by agents to query the knowledge graph. 
# These functions would typically be methods of the KnowledgeGraph class
def get_all_entities(entity_type):
    pass

def get_entity_properties(entity_id):
    pass

def get_relationship_properties(rel_id):
    pass

def get_relationship_entities(rel_id):
    pass

tools = ontology.get_get_tools(
    get_all_entities,
    get_entity_properties,
    get_relationship_properties,
    get_relationship_entities
)
Parameters:
  • get_all_entity_func (function): Function to get all entities of a certain type.
  • get_entity_properties_func (function): Function to get the properties of an entity.
  • get_relationship_properties_func (function): Function to get the properties of a relationship.
  • get_relationship_entities_func (function): Function to get the entities connected by a relationship.
Returns:
  • A list of all “get” tool functions.
