Pilot Implementation

This is an incremental installation release of the pilot implementation of the SysML v2 language, API and services. Release notes are available at

The release also includes both textual notation and XMI versions of the standard model libraries, in the sysml.library and sysml.library.xmi directories. Note, however, that the XMI files use an Eclipse XMI representation (.kermlx and .sysmlx representations) that is not fully normative OMG XMI. The XMI has been exported without derived property values or implied relationships.

To install, download and decompress one of the files below and follow the instructions in the README file.

NOTE. Even though the files below are labeled "Source code", they simply contain the entire compressed contents of this repository. They do not actually include the pilot implementation source code, which is maintained in separate development repositories.

Issue Resolutions

This release includes the Beta 2 specification documents with all issue resolutions approved by the KerML, SysML v2 and Systems Modeling API and Services Finalization Task Forces (FTFs), as delivered for approval by the OMG Architecture Board. While the work of these FTFs is now complete, it is planned to charter a second set of FTFs to continue with additional finalization work. So these specifications must still be considered preliminary.

Resolutions to the following issues are included in this release, in addition to those included previously in release 2024-01. The subclauses of each document affected by a resolution are tagged in the document with the corresponding issue key and title.
