open source Model-Based Engineering Environment
OSSF is using the OpenMBEE
The Open Solar System Foundation (OSSF) will verify the inegrity of candidate space mission architectures to ensure that they are compliant for use in the Lunaverse Common Operational Secenario (COS). These architectures must be submitted in the OpenMBEE integrated environment for engineering with connected models.
open source Systems modeling standard
OSSF is using SysML v2
SysML version 2 (v2) is the next-generation systems modeling language, providing significant enhancements over SysML version 1 in terms of its precision, expressiveness, usability, interoperability, and extensibility.
It is used to specify requirements, behavior, structure, analysis, and verification while maintaining consistency and traceability across all aspects of the system model.
SysML v2 is based on the KerML metamodel, which is grounded in formal semantics. It includes textual syntax in addition to graphical syntax, that allows systems modeling to better leverage automation, emerging technologies such as Artificial Intellogence (AI), and modern development practices.
It also has a standard application programming interface (API) that supports interoperability with other tools and applications spanning the digital engineering ecosystem.
