MDENet Education Platform

The MDENet education platfom aims to allow users to quickly start learning fundamental Model Driven Engineering techniques via a web browser.

The prototype platform is based on the Epsilon Playground and is fork of

github.com/eclipse/epsilon-website/tree/master/playground.

Running the Platform

Note for trying out the education platform there is a dockerised version that provides a complete configuration including tool services. This repository contains only the the platform and token server components. Additional tool services and activities are required for a fully functioning demo.

Prerequisites:

• Node.js
• Docker
• Docker Compose

When using Windows, the following dependencies must be installed globally so they are available on the command line.

npm install -g typescript
npm install -g tsc
npm install -g webpack
npm install -g karma-cli

To start the platform and token server components, in the root project directory run the launch.sh script or run the following commands.

npm run build --workspaces

npm run start --workspace=tokenserver

npm run start --workspace=platform

This starts two web servers

1. the main platform http://127.0.0.1:8080
2. the token server for github authentication http://127.0.0.1:10000

Specifying the activities

The activities configuration file specifies the platform activities to load and must be provided using the activities url parameter.

http://127.0.0.1:8081?activities=[url-to-activity-config]

An example of an activity file for Epsilon tasks provided for testing http://127.0.0.1:8080/?activities=http://127.0.0.1:8082/epsilon-example/epsilon-example_activity.json

The default test configurations provided by the activities server

• consoles/consoles_activity.json - Only console panels
• epsilon-etl/epsilon-etl_activity.json - Epsilon ETL example
• epsilon-example/epsilon-example_activity.json - Epsilon EOL, EVL, and ETL

External tool functions

For activities that use backend tool functions the corresponding tool server must be available to process the requests.

The Epsilon backend docker services for a fully function configuration can be found here.
