A recurring problem when developing a graphical modeler is providing the right layout. The advantage with Sirius is it provides you with a default algorithm that performs an automatic layout of all the elements on a diagram. To illustratep the Sirius’ layout capabilities imagine that we want to visualize the hierarchy of characters in the US TV series House Of Cards. To do this we define the following metamodel: First, we used Sirius to create a diagram representing the Persons. Each person is represented by a white square with his or her name on it. By default Sirius lays out nodes from left to right and what we now have is a flat diagram, with each person on exactly the same level. However what we want to see is the White House organizational hierarchy so we need to represent the subordination link. This link is modeled using the dependsOn reference in the metamodel. Second we define a new relation based edge mapping. This edge will connect Persons, and to find the su...

Just to announce that we (I and some Sirius commiters from Obeo) will start a series of posts about some features available in Sirius. For the ones who don’t know, Sirius is an Eclipse project to quickly define multi view workbenches based on DSL with dedicated representations. Sirius is part of the release train since Luna and its version 3.0 will be available with Mars. A modeling workbench created with Sirius is composed of a set of Eclipse editors which allow the users to create, edit and visualize EMF models. In the next weeks, you will discover posts about diagram customization, tree layout, SVG images… Stay tuned!...

Obeo is proud to announce the release of Obeo Designer 7.0.   This new version integrates Sirius, the Open Source project developed by Obeo and Thales.

This summer was studious for the Sirius team, working on the Open Source solution to create custom modeling workbenches. Just a few months after its first major release in June, here is Sirius 2.0.   Sirius 2.0: performance and user experience   For this release, a special effort was made on the performance and scalability. With test cases composed of more than 500’000 elements, now Sirius is more robust and faster to address your challenges. On the user experience side, more than twenty ergonomic improvements have been made to ease the edition of diagrams. Finally, several new API are now available to execute Sirius in headless mode. As an example, this will help you to programmatically initialize or update diagrams. To discover the full list of enhancements, just take a look at the Sirius 2.0 New & Noteworthy.   Concrete examples gallery   On the occasion of this new version, we have launched a Gallery page on the Sirius web site. Here...

Does your job consist in devising and designing innovative solutions in a complex environment? If this is the case, you will need an efficient tool to describe your design choices, define an architecture, as well as analyze and validate it. What’s more, you must be able to communicate this work to various contacts: your clients, your partners, but also your development teams. Sirius, an Open and Flexible Modeling Solution Sirius meets this need. It’s an Open Source solution from the Eclipse Foundation that enables you to graphically design complex systems (software, business processes, physical, etc.) while keeping the corresponding data consistent (architecture, component properties, etc.). To achieve this, Sirius provides you with a very easy way for creating a customized modeling workbench that is dedicated to your area of expertise and supports your design concept. The product of a collaboration between Obeo and Thales that was started in 2007, Sirius is at the core of the T...
