Scenario
Combined Modeling of
Business Entities of Network Devices

Annotate Model Elements with Constraints
AvailableFor AvailableFor

Proposed Solution
Metamodel-based Integration of
Business Entities Domain-Specific Language (BEDSL)
Feature Oriented Domain Analysis Language (FODA)
Ontology Language (OWL)
Result: Integrated Metamodel
Allows for building one Domain Model containing:
Structure of Devices defined by BEDSL Language
Features defined by FODA Language
Constraints defined by Ontology Language

Metamodel (BEDSL)
BEDSL – Business Entity Domain Specific Language
BEDSL Models (M1 layer) conform to Metamodel (M2 layer)
M2 layer M1 layer BEDSL Metamodel BEDSL Model conformsTo conformsTo

Metamodel (FODA)
FODA – Feature Oriented Domain Analysis
Describe Features and their Relationships
Domain Models (M1 layer) represented as Feature-Tree
M2 layer M1 layer FODA Metamodel FODA Model conformsTo conformsTo

Ontologies
Definition
An Ontology is a Set of Definitions in a formal Language for Terms describing the World
Capability to describe Classes in many different ways and to handle incomplete Knowledge
Allow for complete and sound Reasoning simultaneously on Model and Instance Layer
Different Languages and Syntaxes:
E.g.: OWL2 with Manchester Syntax

Ontologies (Example) OWL Classes and Individuals: M1 layer OWL2 Model

Ontologies (Example)
ObjectProperty: HasPort
Domain:
NetworkDevice
Range:
HasPort exactly 8 Port
ObjectProperty: HasState
Domain:
Port
Range:
HasState exactly 1 State
ObjectProperty : AvailableFor
Domain:
NetworkDevice
NetworkDevice and (hasPort some (Port and hasState some (FreePort)))
EquivalentTo:
NetworkDevice and AvailableFor value AllocatePorts
OWL Object Properties: M1 layer OWL2 Model

Metamodel of OWL2 (Excerpt) M2 layer OWL2 Metamodel

Integration
Integration of BEDSL, FODA and OWL2
Consider Metamodels of BEDSL, FODA and OWL2
Identify Concepts for Integration
Apply Integration Transformations
Merge of Concepts
Create Specialization between Concepts
Create Super Class over Concepts
Create Association between Concepts
Extend Association by Concept
Result: Integrated Metamodel

Integration (BEDSL – OWL)
Merge BEDSL Entity and OWL2 Class
M2 layer M1 layer conformsTo

Integration (BEDSL – OWL)
Create Association between IntegratedClass and ReferenceAttribute
Extend Association to Class ReferenceProperty
Create Specialization between ReferenceProperty and OWL ObjectProperty
M2 layer M1 layer

Integration (BEDSL – OWL – FODA)
Create Specialization between Feature and OWL Individual
M2 layer M1 layer

Conclusion
Consider Metamodels of BEDSL, FODA, OWL2 and identify Concepts
Stepwise Combination of DSL by integrating their Metamodels
Result is integrated Metamodel which allows for building Domain Models simultaneously using BEDSL, FODA and OWL2
