Domain model: Follow Ecore Best Practises

Follow the little pony checklist

NsURI convention

Reference and attribute names are consistent

All the non-abstract EClasses are supposed to be instanciated

A user can’t introduce cyclic references in between model fragments

Iterate: follow Obeo's best practises

A POC generally address

A subset of the target domain

a reduced set of representations

A POC is representation centric

don't care about reliability of domain model

Can be trashed Should be trashed→

Here the goal is to validate the general principle of the tooling, not start the development

Iterate – POC: Design for your users with your users

Tools are easy to configure

Design your ecore model in session validate with domain experts→

Prototype your sirius representations in session Test with targetted users→

Add in the loop internal or external IT integrator

Ideal team :

1 Sirius expert 1 targetted user1 domain expert

Ready-to-use packages

Community Edition Team Edition

foundation

A commercial package completing OD Community with repository-based

collaborative features.

Iterate – POC : project organization

Typical goals for Sirius expert:

To animate a working session

To implement a domain model or review an existing one

To quickly prototype Sirius representations from PPT / Visio specifications

To demonstrate the ability to import / export data with external tools

Average time for POC : 5/20 wd

A Pilot generally address

A subset of the target domain, reliable enough for a real usage

a reduced set of representations, usable by real end users

A Pilot is domain model + UX centric

the domain model should reliable and long term

It should demonstrate a value on some use cases with good feedbacks

The goal is to validate the ROI

Iterate – Pilot: scope

Outcomes

Domain model

Specification and Implementation of a subpart of the EMF domain model

Representations

Completion and Stabilization of the representations started during the POC

or Creation from scratch to be based on good specifications

Enough representation to be able to edit any elements

Basic Tools such as : direct edit, reconnexion, creation, built-in tools usage

Integration

Import / Export, (doc+code) Generators

Challenge

Identify risks and try to solve them

No test on large volumetry

2 weeks at full time for initial setup and workshops

2,5 days of week during 1 month

Sprint for specific features

Support

Mix

1 outsourced Sirius expert 2 internal developper↔

To Sum Up

Focus on the domain model and Stabilize it ASAP

Initialize and design your representations in workshops

Start with a POC

Industrialize with a collaborative editing strategy
