Sirius is an Eclipse-based system designed to quickly create custom multi-view workbenches with minimal technical knowledge. It features a specification environment for developers and a runtime environment for end-users, enhancing the modeling experience through dynamic and customizable tools. The project has received positive feedback and has seen wide deployment across various domains, with upcoming versions aimed at improving usability and performance.

2. What is Sirius?

3. Sirius in a nutshell
● A system to quickly define custom multi-
view worbenches
– Based on graphical editors/modelers
● Based on Eclipse Modeling Technologies
– No need to be an expert for most uses
● New Eclipse Project
– But already proven technology

4. What benefits?
● For developers: reduce cost & complexity
– No need to be a GMF expert
– Dynamic & iterative (live) development
● For end-users
– Tools adapted to their needs and workflows
– Improved experience (compared to raw GMF)

5. Two parts
for two kinds of users
Specification
Environment
(Specifier/Developer)
Runtime Environment
(End-user)

6. The Specification Environment
● Define custom multi-view
workbenches
– Diagrams, Trees, Tables
● With little technical
knowledge
● Get a working modeler fast
– instant feedback
● Highly customizable
– native tooling
– Java or extension points

7. The Runtime
● Executes the
specification
● No code generation
● Environment adapted
to user needs
● Viewpoint-based
● Simplified workflow

12. What one can get…
…in more than 20 minutes
Thales System Engineering
Workbench

13. Sirius in Thales (1/2)
●
A Sirius-based modeling
ecosystem
– From ad-hoc DSLs to
fully industrial products
●
Scalable
– 400+ EClasses,
– 30+ kinds of diagrams
– 1,5+M EOjects (and
counting)
●
Widely deployed
– Dozens of Sirius-
specifiers
– Hundreds of daily-users
of Sirius runtime

14. Sirius in Thales (2/2)
Capella enrichment with domain-specific viewpoints
●
Extensions of the core product
– New representations,
layers, style
customizations
●
Simplistic
– Annotation-based
coloring of elements
●
Advanced
– Performance, Safety,
IVVQ, Product Line,
Computation, Etc.

15. Other Sirius references
● Embedded in the Obeo Designer and Obeo SmartEA
(proprietary) products for 4 years
– many use cases & customers
● At Eclipse.org : EcoreTools 2.0 (Luna)
● Open Source modelers on Github and the
MarketPlace
– Many fields (UML, Risk Analysis, SysML, TOGAF, Entity...)
– 2800+ installs in February 2014
● And now... you!
– Public release v0.9 made available in November 2013
– Version v1.0 planned for Eclipse 4.4 (Luna)

16. Themes for 2014
● Streamline and separate API levels (Core, RCP,
IDE / Diagram,Table...)
● Feedback and error messages for Specifier
● Improve the onboarding experience
● Performance and scalability: aiming at lazyness
● Diagram features: user experience,
compartments
● Support and maintenance

17. Roadmap

18. Conclusion

19. Three things to remember
about Sirius
1. A full-featured environment to create custom modelers
● Easy to use
● Fast, iterative (live) development
2. Mature, many deployements
● Inside Thales and elsewhere via Obeo Designer
3. Official Eclipse project
● around 8 full-time commiters
● Very active support on the Forum
● v0.9 released, v1.0 will be in Luna
