With almost 500 bugzillas between Luna and Mars.1 version, the Sirius team has been very active in bringing more goodness to the technology, most notably : improving and tweaking many aspects of the diagram user experience inherited by GMF enabling new capabilities in the Diagram editors : compartments, streamlined behavior when using images in your modeler enhancing the definition tooling through inferred types, search and navigation and validation constraints improving the scalability and performances of the runtime to support models having 1 million of elements with no fuss This session is going to walk you through demos and technical explanations of what is going on behind the scene. Attendees will leave with a clear understanding of what this new version brings, but also how everything works together, what are the trade-offs to consider and what can be expected from the future versions. [About Cédric Brun: Cedric leads the EcoreTools and Amalgamation components, maintains the Modeling Package, is commiter on several Eclipse projects (Sirius, Acceleo, Mylyn), and is a member of the Architecture Council, Planning Council and the Modeling PMC. He also is the CTO of Obeo, building a broad range of products, from software modernization to enterprise architecture and software factories.]

LONG HISTORY WITH SIRIUS

3. ORIGINS OF AN OSS PROJECT

5. GOING OSS

6. “Sirius is an Eclipse project which aims at providing specific multi-view modeling workbenches
through diagram, table or tree editors based on EMF.
Users can easily define their own modeling workbench, even with very little technical knowledge of
Eclipse, while still being able to deeply customize it when needed.”

7. MISSION STATEMENT
“Lower the barrier of entry to create and
deploy state of the art tools, for any domain
language.”

8. Sirius 0.9
Sirius 1.0
Sirius 2.0
☑ renamed and on Eclipse.org
☑ infrastructure and team 100% operational
☑ up to speed

12. MAJOR VERSIONS!

13. UPGRADING
The runtime handles .odesign and .aird models for you
Easy process :
1. Check release notes for user-visible changes.
2. Change update-site, versions
3. In case of impacting API change, re-check the
for instructions
release
notes
(EcoreTools and UML Designer had no impact whatsoever)

14. WHAT'S NEW SINCE SIRIUS 1.0 ?

15. ACCELEO QUERY LANGUAGE

16. IMPLEMENTATION SPECIFICALLY TAILORED FOR
THE SIRIUS USE CASE

17. SIRIUS USE CASE ?
Many variables for a given expression
nullvalues are common
Navigation with many steps aggregating data
Interactive use : context is constantly changing
Complex or custom logic : Java Services
Predictable ordering and performance overhead .

18. LANGUAGE CHARACTERISTICS
You know OCL ? Then you know AQL
No implicit variables
aql:nameis invalid and become aql:self.name
aql:self.eContents()‐>select(name.startsWith('A'))is invalid and become
aql:self.eContents()‐>select(i | i.name.startsWith('A')
self.referenceWithNoValue.someOtherAttributehas no evaluation error, and returns
"Nothing"
Classic operations : filter, collect
Convenient operations : eInverse(), eResource()..

19. NOT STRICTLY COMPATIBLE* WITH MTL
*: BUT A SUBSET OF MTL WORKS FOR BOTH

20. QUERIES ENGINES -- OVERHEAD BENCH

22. in preference to Acceleo 3 or OCL
simpler for querying EMF models
more concise and very easy to learn
improved code completion
improved syntax errors detection

23. RECOMMENDED QUERY LANGUAGE FOR SIRIUS 3.1.0
