Key Features
Standard Compliant
SysON aims at providing an implementation of the OMG’s specification SysMLv2: language concepts, REST API, and interoperability textual format.
Web-Based
Graphical, form-based and tabular structured editors that can be used from a web browser, without any specific installation on user’s desktop.
Open Source
Hosted in the Eclipse community, SysON aims to catalyze industrial collaboration, accelerate innovation, and foster the adoption of SysMLv2.
Why SysON
SysML was created in 2005 as a standard for systems engineering to elevate the role of models as primary tools for communication and documentation.
With system complexity continuing to escalate exponentially, and Digital Engineering emerging as a pivotal pillar to address an ever-challenging world, SysMLv2 has been specified as the next-generation systems modeling language to improve precision, expressiveness, and usability.
SysON’s objective is to provide System Engineers with super easy access to this new standard, at minimal cost and great ease of use, with the guarantee of interoperability with other open-source MBSE tools notably Capella and Papyrus.
This will be achieved through three means: the support of the SysMLv2 standard, the use of state-of-the-art web technologies, and an open-source approach.
