Context

Forge is an on-line service that allows to instantiate, compose and manage collaborative services.

Collaborative services are traditionally Version Control Systems, Bug Trackers, Forums, Mailing list, Wikis etc.


3

Motivations

Many forges are available today Gforge, Trac, Launchpad, Codendi,

FusionForge, Sourceforge, GoogleCode, CodePlex, etc.

Very hard to bootstrap an eco-system


4

Factory User Story

The targeted user of the QualiPSo Factory is the developer of a new forge service

A forge service developer must be able to create a new collaborative service very easily


5

Qualipso Factory Architecture

The QualiPSo Factory is based on a component model

Core services are provided by the forge Authentication, access control, binding,

events, indexation, semantic Forge service developers reuse core/

existing services to develop new collaborative services

Qualipso Factory Architecture

Technologies used: Java EJB3 Web-fragment (Servlet 3.0 specification) GWT (Google Web Toolkit)

Tools used Maven Eclipse JBoss

Factory Benefits

The factory core is a kernel to bootstrap an eco-system The kernel is maintainable, dependable and usable.

The QualiPSo Factory allows composition of services i.e. the workflow service orchestrate project

creation. The QualiPSo Factory allows composition of

resources i.e. create complex resource by composing simple resource. i.e. a “File” resource can be child of a “Forum”

resource or a “Issue” resource.

Developing Factory Services


11

Creating a new Abstract Service

Steps for adding factory services

1. Instantiate an empty project with maven archetype

2. Define Service Interface3. Implements Service4. Test service locally5. Publish your Service

6. Assemble your new service with existing ones7. Deploy your assembly8. Run external service tests

Results

The developer of a new forge service is the targeted user of the QualiPSo Factory

A forge service developer is able to create a new collaborative service very easily by following the provided methodology

This QualiPSo Factory component model allows to fulfill these objectives


Developing Factory Services UI


15

Objectives

Extrapolate the same component model, but on the UI side

Use the same tools, the same language, the same methodology, the same model


16

Building UI Component

Steps to develop a new UI Component

1. Create new service UI using maven archetype 2. Define components Views3. Define components Events4. Implements component Views5. Implements server communication6. Test server communication and UI locally7. Assemble your new service with existing services8. Deploy your assembly9. Run external tests (selenium)

Results

Created a component model based on GWT allowingseparated component development and cold assembly

UI Components are maven-based as abstract services

Same language for abstract services and UI components

Complete development process can be done in the same IDE

Integration in a Single Page Composite Interface


19

Conclusion

The kernel component model gives developers the ability to contribute easily writing server side and also client side (UI) extensions in a uniform way

QualiPSo Factory aims to promote the emergence of a forge eco-system
