UML (Unified Modeling Language)

• De facto standard software modeling language– Standardized for 10 years already– Very popular but still not used by everyone– UML extension mechanisms are not anything new!– UML tools are starting to develop features for DSL

UML Extension Elements

• Profile is a reusable set of UML extensions• Stereotype extends semantics of standard UML

metaclass(es) and may also define additional properties and custom appearance icon– Tag Definition specifies additional property that is not

available in the extended metaclass(es)

• Constraint is a rule for domain-specific model correctness or completeness

• Also: Data Type, Enumeration, …


Stereotype Definition and Application

<<Employee>>Darius Silingas

{e-mail = "[email protected]" , first name = "Darius" , last name = "Šilingas" , phone = "+37068612748" }

<<Employee>>Darius Silingas

<<Employee>>

e-mail = "[email protected]"first name = "Darius"last name = "Šilingas"phone = "+37068612748"

<<metaclass>>Class

<<stereotype>>Employee

Problems of UML Profiles

• UML modeling environment is too complex

• Applying stereotype doesn’t hide the UML properties, terminology, etc.

• Difficult to restrict usage of standard UML elements and ensure model correctness


MagicDraw UML DSL Engine

Custom Diagram Wizard– Custom diagram for DSL profile with custom toolbar

elements, symbol styles, smart manipulators

DSL Customization– DSL stereotype appearance as first-class element– Custom specification editors– Custom context menus– Additional rules for model initialization and restrictions

Enhanced UML Profiling– Tag grouping, hiding stereotypes and tags,

customizing paths, etc.

Workflow for Creating DSL Environment

1. Define DSL metamodel

2. Map DSL metamodel to UML profile

3. Create DSL sample

4. Define customizations for stereotypes

5. Define validation rules

6. Create custom DSL diagram

7. Test the created DSL environment

1. Define DSL Metamodel

2. Map DSL Metamodel to UML Profile

<<stereotype>>Organization

<<stereotype>>Project

<<stereotype>>OrganizationRole

3. Create DSL Sample

• Should represent all major aspects of DSL!

<<OrganizationUnit>>

Training

<<Employee>>Darius Šilingas

<<Employee>>

e-mail = "[email protected]"phone = "+37068612748"skills = English UML 2 MDA DSL

<<OrganizationRole>>Principal Trainer

<<Employee>>Ruslnas Vitiutinas

<<Skill>>openArchitectureWare

<<Skill>>Java Programming

<<Skill>>DSL

<<Skill>>English

<<Skill>>MDA

<<Skill>>UML 2

<<Supervise>><<RoleAssignment>>


4. Create Customizations for Stereotypes

• Customizations are model elements, part of profile!

<<Customization>>EmployeeCustomization

<<Customization>>

allowedRelationships = RoleAssignment SupervisecustomizationTarget = EmployeehideMetatype = truepossibleOwners = OrganizationUnit


5. Define Validation Rules

• Employees can be placed only in organization units

• Validation rules are constraints, part of profile!• Possibility to validate the user model against the rule!!


{owner.oclIsKindOf(OrganizationUnit)}



6. Create Custom DSL Diagram

• Custom diagrams can be exported to XML descriptors and imported in other machines!


7. Test the Created DSL Environment

• Demonstration in MagicDraw UML


Enabling the Full Power of DSL

Create DSL-specific transformations– Model reports– DSL-specific patterns– Model 2 Model transformations– Model 2 Code transformations

Create guidance for DSL modeling– Project templates– Samples and tutorials– Modeling wizards– Reusable model libraries


Why UML Profiles?

• Reuse of modeling environment features– Single modeling environment for different roles

• Possibility to use the extensions in standard UML diagrams– e.g., assign project role to activity swimlane

• Standardized model data storage and ability to interchange data between tools– MDA tools can be used for code generation
