Slides used for the EclipseCon EU 2016 talk: https://www.eclipsecon.org/europe2016/session/be-serious-sirius-your-journey-first-experimentation-large-deployment-sponsored-obeo



Sirius is the Eclipse project that allows you to easily create custom graphical modeling tools dedicated to your own business domain.

In this talk we will explain and illustrate how to successfully deploy industrial-strengh modeling workbenches based on Sirius.

In particular, we will show how to collaborate with other team members by storing your models and representations (diagrams, tables, matrices, trees) in a shared repository. This solution based on CDO provides a fine-grained locking mechanism that allows you simultaneously work on visual representations for the same data, without losing time managing conflicts and without any technical skills.

During this talk, you will also discover the solutions provided by the creators of Sirius to help you stay on the right tracks, from first hands-on to large deployments.

  30. 30. 30 ©Copyright2016Obeo 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
  31. 31. 31 ©Copyright2016Obeo 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
