class mstrio.modeling.schema.fact.fact.Fact(connection, id=None, name=None, show_expression_as=ExpressionFormat.TREE)¶

Bases: Entity, CopyMixin, DeleteMixin, MoveMixin

Python representation for Strategy One Fact object.

Parameters:

connection (Connection) –
id (str | None) –
name (str | None) –
show_expression_as (ExpressionFormat | str) –

id¶: fact’s ID

name¶: fact’s name

sub_type¶: string literal used to identify the type of a metadata object

description¶: fact’s description

type¶: object type, ObjectTypes enum

subtype¶: object subtype, ObjectSubTypes enum

ext_type¶: object extended type, ExtendedType enum

ancestors¶: list of ancestor folders

date_created¶: creation time, DateTime object

date_modified¶: last modification time DateTime object

destination_folder_id¶: a globally unique identifier used to distinguish between metadata objects within the same project

is_embedded¶: if True indicates that the target object of this reference is embedded within this object. Alternatively if this object is itself embedded, then it means that the target object is embedded in the same container as this object

data_type¶: dataype that the engine should use to store a intermediate values for this fact, DataType object

expressions¶: Array with a member object for each separately defined expression currently in use by a fact. Often a fact expression takes the form of just a single column name, but more complex expressions are possible.

entry_level¶: this is the natural level (in other words a set of attributes) of the fact. This property is not set by the architects. Instead it is deduced by the platform by examining the specification of the fact, and considering the attributes and the relationships between them. Because it can only be computed by considering the schema as a whole, the value is not automatically updated each time the fact is modified. It will be correct following a schema update operation.

owner¶: User object that is the owner

acg¶: access rights (see EnumDSSXMLAccessRightFlags for possible values)

acl¶: object access control list

version_id¶: the version number this object is currently carrying

hidden¶: Specifies whether the object is hidden

Add Access Control Element (ACE) to the object ACL.

Note

To add rights for the Root Folder and the Freeform Objects, apply the required rights for these folders:
