Object Management Group Approves SysML V2, Beta Specifications
New specifications enable next-generation systems modeling

BOSTON, MA – JULY 10, 2023 – Today, international technology standards organization Object Management Group® (OMG®) announced it approved the Systems Modeling Language (SysML) version 2 beta specifications. These include: the Kernel Modeling Language (KerML) specification version 1.0 beta, the Systems Modeling Language (SysML) specification version 2.0 beta, and the Systems Modeling Application Programming Interface (API) and Services specification version 1.0 beta.

The specifications enable next-generation systems modeling with improved precision, expressiveness, consistency, usability, interoperability, and extensibility over SysML version 1. The submission concluded five years of development, resulting in the three specifications and an open-source pilot implementation to validate them. The SysML v2 Submission Team, with co-leaders Sandy Friedenthal and Ed Seidewitz, included representatives from more than 80 organizations.

"SysML v2 enables the modeling of increasingly complex systems as part of the evolving practice of model-based systems engineering," said Friedenthal. "Our team had tremendous talent from various domains, including end-users, academia and researchers, and tool vendors."

SysML v2 extends KerML to include concepts for modeling systems with deeply nested hierarchies of structure, behavior, requirements, and cross-cutting relationships. It also enables developers to specify analysis and verification cases. "KerML defines a new metamodel to provide the foundation for SysML v2," said Seidewitz. "Its formal semantics specified as first-order logic, with 4D semantics of temporal and spatial extent, provide a new level of expressivity and precision."

SysML v2 provides complementary textual and graphical representations of the underlying model, facilitating improved system understanding. A standard API and associated set of services to navigate, query, and update the model enables interoperability with other tools and software applications throughout the life cycle of system development.

OMG anticipates final adoption of the three specifications in 2024. OMG specifications address middleware, modeling, and vertical domain frameworks. All OMG specifications are available from the website.
