bento_meta.objects

This module contains the subclasses of Entity which are used in representing the models contained in the MDB.

Module Contents

Classes

Node	Subclass that models a data node.
Property	Subclass that models a property of a node or relationship (edge).
Edge	Subclass that models a relationship between model nodes.
Term	Subclass that models a term from a terminology.
ValueSet	Subclass that models an enumerated set of Property values.
Concept	Subclass that models a semantic concept.
Predicate	Subclass that models a semantic link between concepts.
Origin	Subclass that models a Term 's authoritative source.
Tag	Subclass that allows simple key-value tagging of a model at arbitrary points.

Functions

mergespec(clsname, attspec, mapspec)

Merge subclass attribute and mapping specification dicts with the

bento_meta.objects.mergespec(clsname, attspec, mapspec)

Merge subclass attribute and mapping specification dicts with the base class’s. Not for human consumption.

property terms

If the Property has a value_set domain, return the Term objects of its ValueSet

property values

If the Property as a value_set domain, return its term values as a list of str. :return: list of term values :rtype: list
