JUMP: Discover Libraries

It allows to extract UML Profiles from Java annotations – Example shown: JPA Library

– To execute it: right click on

the jpa2 project and select

Model Discovery Toolbox ->

UML Profile Discovery

– More UML Profiles have been discovered by JUMP • They can be installed as Eclipse plugins

• https://code.google.com/a/eclipselabs.org/p/uml-profile-store/source/browse/#git%2FUMLProfiles

JUMP: Discover PSM + Libraries (RE)

Execute JUMP on the petstore-app

– In order to execute it, right click on the

petstore-app and select

Model Discovery Toolbox ->

Profiled UML Model Discoverty

output (PSM of the Petstore)

input (Petstore application)

output (Profile with stereotypes of the Petstore)

1. Understanding (I) (RE)

Based on the JPA

annotations, we

are interested

only in the

domain model

launch configuration

output (Sliced PSM of the Petstore containing the domain model)

input (PSM of the Petstore) Some profiles of the UML Profile Store are also taken as input

2. Understanding (II) (RE)

We want to obtain

a PIM from the PSM

– Remove all

stereotypes

– Turn some plain

associations into

composition

3. Modernisation (I) (FE)

Refine the PIM

into a PSM cloud-

compatible

– Addition of the

Objectify Profile

Input (PIM of the Petstore containing the domain model)

Output (PSM of the Petstore domain model with stereotypes from Objectify)

4. Modernisation (II)(FE)

The PSM is

further refined

by adding

service classes

– They contain

Objectify

instructions

Input (PSM of the Petstore domain model with stereotypes from Objectify)

Output (PSM of the Petstore domain model with service classes)
