XMI Export from Papyrus to Enterprise Architect: Do stereotypes and diagram layout survive round‑trip?
Goal Validate that a UML model exported as XMI from Eclipse Papyrus can be imported into Sparx Enterprise Architect without losing applied stereotypes, tagged values, or diagram layout information. Constraints & Uncertainty The XMI header specifies the UML metamodel version; a mismatch between Papyrus (e.g., UML 2.5) and Enterprise Architect may cause el
UML 2.5 Stereotype Application Lacks Mandatory Visibility Constraints
Missing Visibility Enforcement for Stereotyped Elements The UML 2.5 specification defines stereotypes as reusable profile extensions but does not prescribe a mandatory visibility constraint for the elements they annotate. This omission leaves tool-specific behavior undefined: a stereotype applied to a class marked private may be rendered public in generated
Multiplicity Constraint Violation in Association Class Definitions
In UML class diagrams, an Association Class is designed to hold properties that belong to the relationship between two entities rather than the entities themselves. According to the specification, an Association Class represents a unique link between participating instances. A conflict arises when attempting to define multiplicity constraints on the Associat
FinalNode must not have outgoing ActivityEdges — model validation fails on activity final node
I am modeling an activity in UML 2.5.1 and my validator flags the model as invalid when an activity final node has an outgoing control flow. My understanding is that the Activities clause defines a well-formedness rule: a FinalNode (both activity final node and flow final node) must not have outgoing ActivityEdges, and violating it makes the model non-confor
unifiedmodelinglanguageUML Sequence Diagram Combined Fragment Nesting Limits
Interaction Flow Control The Unified Modeling Language (UML) specification defines combined fragments to manage interaction flow through operators such as alt , opt , loop , and par . These fragments allow developers to model conditional logic and concurrency within a sequence diagram. Execution Semantics in Nested Fragments While the individual operators ha
UML 2.5.1 Visibility: Protected Modifier Mapping Across Architectural Layers
In UML 2.5.1, visibility modifiers such as Public (+), Private (-), and Package (~) are used to define encapsulation boundaries for attributes and operations within a classifier. While these notations map clearly to most object-oriented languages within a single module, ambiguity arises when modeling transitions between distinct architectural layers. The goa
Proprietary Graphical Formats vs. Text-Based XMI for Version Control
Model Serialization Trade-offs Establishing a repeatable development environment for UML requires a consistent method for storing and versioning model files. The goal is to ensure that architectural diagrams can be tracked, diffed, and merged across a distributed team without losing structural integrity. The Constraint Graphical editors often utilize proprie
InterruptibleActivityRegion missing default timeout for interrupting edges
Goal Define a portable default timeout that governs how long an interrupting edge may wait before forcing cancellation of an InterruptibleActivityRegion. Constraints and uncertainty The UML 2.x specification describes InterruptibleActivityRegion and interrupting edges but does not prescribe a default timeout duration. AcceptEventAction can consume time event
