From UML (Fondue) to COOPN

An iterative approach applying MDA techniques

Outline

• Motivation and general approach• Some background

Fondue Specification The MDA approach

• Some steps towards the transformation Relationship between Fondue “components” and

COOPN “components”

• Tools, tools and another process diagram• Status report

Some Background

• Fondue What it provides

• Concept Model: Defines the static structure of the information in the system• Behavior Model: Defines the Input and Output communication of the system

Uses UML for notation (parts of different UML diagrams• Concept Model Class Diagram• Environment Model Collaboration Diagram• Protocol Model State Diagram• Operation Model (OCL)

Describes operations by operation schemas which specify operations by pre- and post conditions using OCL

The Fondue process can be outlined by a UML class diagram showing usage dependencies between the models

transformed into models in other languages

Some steps towards transformation

• Describe CO-OPN as a MOF Model Use UML notation to define CO-OPN Meta

Model Get XMI[UML] Convert XMI[UML] to XMI[MOF] Generate JMI from XMI[MOF] Use generated JMI to add and browse CO-

OPN repositories

Luis Pedro 9

Some steps towards transformation

• Fondue is already described as a MOF Model

Some steps towards transformation

• Concept Model 1 Class 1 CO-OPN Class

• Name Name• Attributes Places • Access methods: put, get, read

Method put_a(x):: a y -> a x;• Gate get_a(x):: a x -> a x;• Gate read_a(x)::a x:: -> a x;

• Associations as classesWith source and target values• Instantiation of AADT Bag• For each class

Some steps towards transformation

• Operation Model Transform Fondue pre and post-conditions

using OCL• Operation Schemas (synchronization rules, algebraic

equations)

•No standard •approach available!

•Parse OCL and define clear •transformation rules

Tools, tools and another process diagram

• Create(Draw) COOPN Meta Model MagicDraw

• Export as XMI[UML] MagicDraw

• Convert XMI[UML] to XMI[MOF] Uml2mof

• MDR-StandAlone package: jmi.jar; jmiutils.jar; mdrapi.jar; mof.jar; nbmdr.jar; openide-util.jar

• UML Standard definition: UML_Standard_Profile.xml• <XMI xmi.version='1.2' timestamp='Thu Jan 20 12:03:39 CET 2005' xmlns:UML='omg.org/UML/1.4'> <XMI.header> <XMI.documentation> <XMI.exporter>MagicDraw UML</XMI.exporter> <XMI.exporterVersion>9.0</XMI.exporterVersion> </XMI.documentation> <XMI.metamodel xmi.name='UML' xmi.version='1.4'/> </XMI.header>

Tools, tools and another process diagram

• Create Fondue Model Together + Fondue pluggin

• Use JMI to load both Fondue and COOPN meta repositories Any Java IDE (e.g. IDEA)

• Add rules to perform transformation

Status report

• All set of SW in place• COOPN Meta Model

UML sketches XML generation

• Fondue in Mac OS X• Sample SW to browse Fondue modules

Task list

• Prepare some documentation

• Continue the COOPN Meta Model

• Proof of concept: small application to browse a COOPN model using MetaModel COOPN builder module

• Formalization of transformation rules
