This blog post presents the requirements about properties, values, and expressions for SysML v2. It is part of a blog post series about the upcoming new SysML v2 and SysML API & Services standard. The blog posts present the requirements for the standard stated in the request for proposals (RFP) published by the OMG. See end of this post for a list of all posts of this series including a link to the first post of the series that provides...

This blog post presents the cross-cutting requirements for SysML v2. It is part of a blog post series about the upcoming new SysML v2 and SysML API & Services standard. The blog posts present the requirements for the standard stated in the request for proposals (RFP) published by the OMG. See end of this post for a list of all posts of this series including a link to the first post of the series that provides an overall introduction. The cross-cutting...

This blog post presents the SysML v2 language architecture and formalism requirements. The previous blog post gave an overview of the general requirements on proposals for OMG Request for Proposals (RFP). Following blog posts present details of specific sections of the RFP’s. A fundamental concept of a modeling language architecture is the metamodel. It defines the concepts of the language. For example, the following figure depicts a simplified extract of the UML metamodel. The figure shows the definition of the UML model...

This blog post gives you a brief overview of the general requirements on proposals for SysML v2 and the SysML API & Services. The previous blog post gave an overview of the RFP’s. Following blog posts present details of specific sections of the RFP’s. The general requirements are valid for all proposals for OMG specifications and are not specific to SysML. So, some of them are only partially relevant for SysML. General requirements If a proposal uses models, it shall use an OMG...

It is time for the next generation of the Systems Modeling Language (SysML). More than 10 years ago the Object Management Group (OMG) published SysML version 1.0 to provide a simple but powerful modeling language for a wide range of systems engineering problems. We have learned a lot from many industrial applications of SysML. That includes the benefits as well as the limits of SysML. Additionally, model-based systems engineering is getting more and more popular and leads to more requirements for...
