OMG System Modeling Language™ (SysML®) v2 Release

The SysML v2 Release repository contains the latest incremental release of the SysML v2 specification documents, example models and model library. It also provides instructions for user installation of SysML v2 Pilot Implementation editors. For developer installs, please see the development repositories also available from the Systems Modeling organization on GitHub.

Team

The SysML v2 Submission Team (SST) is a joint team of over 160 individuals from over 70 industry, academia and government organizations, working together to develop the next major version of the Object Management Group (OMG) System Modeling Language (SysML). The goal is to deliver a SysML v2 specification that is validated by the user community, that is demonstrable with a pilot implementation and that provides a smooth migration path for SysML v1 users and models.

The proposed SysML v2 specification will be submitted to the OMG in response to two Requests for Proposals (RFPs), which are publicly available at http://www.omg.org:

• Systems Modeling Language (SysML) v2 RFP (ad/2017-12-02)
• Systems Modeling Language (SysML) v2 API and Services RFP (ad/2018-16-03)
