I had the pleasure to participate to EclipseCon 2022 last October, near Stuttgart in Germany. It was a great conference and the opportunity to meet with the Eclipse community. I was there with several other members of the Obeo team to share our work on Sirius Web . I had the chance to be part of the program, with Benoît Lelandais from the CEA DAM (Military Applications Division of the French Nucle...

Some very well known languages propose a graphical and a textual representation, this is notably the case of two modeling languages: UML and SysML v2. In order for Eclipse Sirius Web to adapt to the needs of any modeler, it is important that it can be used to express a model in this way. In 2017, we published with TypeFox a white paper about how a textual representation can be combined with a grap...

Did you know? The whole world depends on one company. And it uses technologies developed by Obeo. This company is ASML , the only one in the world to master the technology of printing miniature electronic circuits. Those that equip most of our modern equipment: telephones, cars, data centers, etc. ASML supplies all the major semiconductor suppliers in the world, starting with Samsung and Intel. Ea...

Last June, during SiriusCon 2022, I presented a talk to explain the basics of Sirius Web . My objective was to show what kind of graphical modeling tool you can create with Sirius Web, without writing a single line of code. Unlike a diagramming tool that only allows users to create drawings, a modeling tool also manages the data that is graphically represented, ensuring a bi-directional correspond...

When creating a model with the Sirius Diagram Editor, the style of the diagram elements can be modified according to the user's requirements: the elements can be resized, the color can be changed and images can be used to represent the elements.   The user experience has been improved with Sirius 7.0.0 to use images in diagrams. This new feature is available through the “Set style to Workspace Ima...

When creating your own graphical modeler using Eclipse Sirius Desktop , you need to tell Sirius: how to interpret your domain models so they can be displayed, and how your domain elements must be modified when the end-user invokes edition tools (e.g. direct edit, element creation or deletion, etc.). This is done using a combination of interpreted expressions (in general using AQL ) and model opera...

This post is for you if you want to build web-based graphical modeling tools. Eclipse Sirius is an open-source project to create domain-specific modeling workbenches. At this point, if you are not aware of “modeling and domain-specific blablabla”, you might wonder “ What does it mean and why should I care? ”. Give semantics to your drawing… That is simple, you have data (and I am pretty sure you h...
