PRMS Report

Abstract

• This report developes the idea of a visual graphical editor for Epsilon and the process of developing it.
• A fully working epsilon workflow builder and visualizer is also presented that helps users to compose Epsilon workflows and construct visual representations from textual ones.

Statement of Ethics

• Informal user survey for requirements.
• Formal user survey to evaluate the tool ?

Introduction

Motivation

• Why EWE ? What is the need ?
• Workflow inherently visual - flow of order of tasks.
• e.g. BPM tools all provide editors.
• MDE is essentially a sequence of steps from start to finish.
• Other model management languages, frameworks tools provide it as well. (Atlas, OpenAW, etc)
• Therefore Epsilon, needs one too.

Method

• Documents the process of building such a tool using MDE techniques and Epsilon itself.

Literature Review

• Model driven engineering - tasks involved. Tasks constitute a workflow.
• How does Epsilon handle it ? Internal architecture of Epsilon Workflow.
• ANT, Java Modules, Eclipse Launch configuration, Working outside Eclipse.
