Package

Package is defined in KerML specification on page 264. Excerpt from the machine readable specification:

A Package is a Namespace used to group Elements, without any instance-level semantics. It may have one or more model-level evaluable filterCondition Expressions used to filter its importedMemberships. Any imported member must meet all of the filterConditions.

The following diagram shows the inheritance hierarchy of Package according to the specification:

// Class: Package digraph { Package [label="Package (KerML)" shape=plaintext] Namespace -> Package Namespace [label="Namespace (KerML)" shape=plaintext] Element -> Namespace Element [label="Element (KerML)" shape=plaintext] }

The following table shows all attributes defined for Package according to the specification together with the documentation from the machine readable specification. Note that in SysIDE API, we use snake case for attribute names instead of Pascal case used in the specification.

Attribute	Documentation from machine readable specification
Attributes defined in `Package`:
`filter_conditions`	The model-level evaluable `Boolean`-valued `Expression` used to filter the `members` of this `Package`, which are owned by the `Package` are via `ElementFilterMemberships`.
Attributes defined in `Namespace`:
`owned_memberships`	The `ownedRelationships` of this `Namespace` that are `Memberships`, for which the `Namespace` is the `membershipOwningNamespace`.
`owned_members`	The owned `members` of this `Namespace`, which are the `ownedMemberElements` of the `ownedMemberships` of the `Namespace`.
`memberships`	All `Memberships` in this `Namespace`, including (at least) the union of `ownedMemberships` and `importedMemberships`.
`owned_imports`	The `ownedRelationships` of this `Namespace` that are `Imports`, for which the `Namespace` is the `importOwningNamespace`.
`members`	The set of all member `Elements` of this `Namespace`, which are the `memberElements` of all `memberships` of the `Namespace`.
Attributes defined in `Element`:
`element_id`	The globally unique identifier for this Element. This is intended to be set by tooling, and it must not change during the lifetime of the Element.
`declared_short_name`	An optional alternative name for the `Element` that is intended to be shorter or in some way more succinct than its primary `name`. It may act as a modeler-specified identifier for the `Element`, though it is then the responsibility of the modeler to maintain the uniqueness of this identifier within a model or relative to some other context.
`declared_name`	The declared name of this `Element`.
`short_name`	The short name to be used for this `Element` during name resolution within its `owningNamespace`. This is derived using the `effectiveShortName()` operation. By default, it is the same as the `declaredShortName`, but this is overridden for certain kinds of `Elements` to compute a `shortName` even when the `declaredName` is null.
`name`	The name to be used for this `Element` during name resolution within its `owningNamespace`. This is derived using the `effectiveName()` operation. By default, it is the same as the `declaredName`, but this is overridden for certain kinds of `Elements` to compute a `name` even when the `declaredName` is null.
`qualified_name`	The full ownership-qualified name of this `Element`, represented in a form that is valid according to the KerML textual concrete syntax for qualified names (including use of unrestricted name notation and escaped characters, as necessary). The `qualifiedName` is null if this `Element` has no `owningNamespace` or if there is not a complete ownership chain of named `Namespaces` from a root `Namespace` to this `Element`.
`is_implied_included`	Whether all necessary implied Relationships have been included in the `ownedRelationships` of this Element. This property may be true, even if there are not actually any `ownedRelationships` with `isImplied = true`, meaning that no such Relationships are actually implied for this Element. However, if it is false, then `ownedRelationships` may not contain any implied Relationships. That is, either all required implied Relationships must be included, or none of them.
`is_library_element`	Whether this Element is contained in the ownership tree of a library model.
`owning_membership`	The `owningRelationship` of this `Element`, if that `Relationship` is a `Membership`.
`owned_relationships`	The Relationships for which this Element is the owningRelatedElement.
`owning_relationship`	The Relationship for which this Element is an ownedRelatedElement, if any.
`owning_namespace`	The `Namespace` that owns this `Element`, which is the `membershipOwningNamespace` of the `owningMembership` of this `Element`, if any.
`owner`	The owner of this Element, derived as the `owningRelatedElement` of the `owningRelationship` of this Element, if any.
`owned_elements`	The Elements owned by this Element, derived as the ownedRelatedElements of the ownedRelationships of this Element.
`documentation`	The Documentation owned by this Element.
`owned_annotations`	The `ownedRelationships` of this `Element` that are `Annotations`, for which this `Element` is the `annotatedElement`.
`textual_representations`	The `TextualRepresentations` that annotate this `Element`.
