pyirk._builtin.statement_utils

Statement-/relation-utility functions extracted from :mod:pyirk.builtin_entities.

Like the sibling modules :mod:pyirk._builtin.taxonomy, :mod:pyirk._builtin.scopes, :mod:pyirk._builtin.math_expressions and :mod:pyirk._builtin.operators, this module only binds the (partially loaded) builtin_entities module object as _be. All accesses to its module-globals (items like I40, I41, relations like R20, R57, R62 and already migrated helpers like instance_of) happen module-qualified and exclusively at call time inside the function bodies — never at import time. core/Entity/Relation/Item/Statement/ ds/RuleResult are imported directly from :mod:pyirk.core.

Functions

set_multiple_statements	For every element of subjects, create a statement with predicate and object
get_relation_properties_uris
get_relation_properties	return a sorted list of URIs, corresponding to the relation properties corresponding to rel_entity.
label_compare_method	Condition function for rules. Returns True if label of item 1 is alphabetically smaller then that of item2
does_not_have_relation	Condition function for rules. Returns True if item does not have any statement where rel is the predicate
replacer_method	replace old_item with new_item in every statement, unlink the old item
copy_statements	For every statement like (i1, rel1, i2) create a new statement with rel2 as predicate.
reverse_statements	For every statement like (i1, rel1, i2) create a new statement (i2, rel, i1) (if it does not yet exist).
new_instance_as_object	Create a new instance of obj_type and then use this as the object in a new statement.
raise_contradiction
raise_reasoning_goal_reached

pyirk._builtin.statement_utils.set_multiple_statements(subjects: Union[list, tuple], predicate: pyirk.core.Relation, object: Any, qualifiers=None)

For every element of subjects, create a statement with predicate and object

pyirk._builtin.statement_utils.get_relation_properties_uris()

pyirk._builtin.statement_utils.get_relation_properties(rel_entity: pyirk.core.Entity) → List[str]

return a sorted list of URIs, corresponding to the relation properties corresponding to rel_entity.

pyirk._builtin.statement_utils.label_compare_method(self, item1, item2) → bool

Condition function for rules. Returns True if label of item 1 is alphabetically smaller then that of item2

pyirk._builtin.statement_utils.does_not_have_relation(self, item: pyirk.core.Item, rel: pyirk.core.Relation) → bool

Condition function for rules. Returns True if item does not have any statement where rel is the predicate

pyirk._builtin.statement_utils.replacer_method(self, old_item, new_item)

replace old_item with new_item in every statement, unlink the old item

pyirk._builtin.statement_utils.copy_statements(self, rel1: pyirk.core.Relation, rel2: pyirk.core.Relation)

For every statement like (i1, rel1, i2) create a new statement with rel2 as predicate.

pyirk._builtin.statement_utils.reverse_statements(self, rel: pyirk.core.Relation)

For every statement like (i1, rel1, i2) create a new statement (i2, rel, i1) (if it does not yet exist).

pyirk._builtin.statement_utils.new_instance_as_object(self, subj, pred, obj_type, placeholder=False, name_prefix=None)

Create a new instance of obj_type and then use this as the object in a new statement.

pyirk._builtin.statement_utils.raise_contradiction(self, msg_template, *args)

pyirk._builtin.statement_utils.raise_reasoning_goal_reached(self, msg_template, *args)
