What is a SysML Package diagram?
Definitions
Package: A Package (notation: "folder" icon) is a general-purpose mechanism for organizing model elements and diagrams into groups. Packages define unique namespaces for model elements defined within their scope.
- namespace = a declarative region that provides scope for the identifiers contained within
Package diagram (pkg): A Package diagram is a static structural diagram that shows the relationships among packages and their contents. Package can be stereotyped (customized) for organizing model elements into models, views, model libraries, and frameworks.
Purpose
The purpose of Package diagram is to support the organization and management of large, complex System Architecture Models (SAMs).
