bento_meta.objects

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

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.
`Model`	Subclass with information regarding data model.

Functions

mergespec(→ tuple[dict[str, str], dict[str, ...)

Merge subclass attribute and mapping specification dicts with the base class's.

Module Contents

bento_meta.objects.mergespec(clsname: str, attspec: dict[str, str], mapspec: dict[str, str | dict[str, str]]) → tuple[dict[str, str], dict[str, str | dict[str, str]]][source]

Merge subclass attribute and mapping specification dicts with the base class’s.

Not for human consumption.

class bento_meta.objects.Node(init: dict | neo4j.graph.Node | Node | None = None)[source]

Bases: bento_meta.entity.Entity

Subclass that models a data node.

attspec_

mapspec_

property annotations: If the Node is annotated by Term`s via a `Concept, return the `Term`s

get_key_prop() → Property | list[Property] | None[source]

Return the Property entity with is_key=True for this Node if it exists.

If multiple key props exist, return a list of them; if none exist, return None.

class bento_meta.objects.Property(init: dict | neo4j.graph.Node | Property | None = None)[source]

Bases: bento_meta.entity.Entity

Subclass that models a property of a node or relationship (edge).

pvt_attr = ['pvt', 'neoid', 'dirty', 'removed_entities', 'attspec', 'mapspec', 'belongs', 'value_types']

attspec_

mapspec_

defaults

value_types = []

property annotations: If the Property is annotated by Term`s via a `Concept, return the `Term`s.

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

Bases: bento_meta.entity.Entity

Subclass that models a relationship between model nodes.

defaults

attspec_

mapspec_

property annotations: If the Edge is annotated by Term`s via a `Concept, return the `Term`s

property triplet

(edge.handle, src.handle, dst.handle) src and dst attributes must be set.
