Pilot Implementation
This is an incremental installation release of the pilot implementation of the SysML v2 language, API and services. Release notes for the language and API pilot implementations are available at
The API Cookbook is still unchanged from 2024-02.
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 Beta 2.3 versions of the specification documents, which update the published Beta 2 versions with issue resolutions approved in the recent ballots of the second SysML v2 and System Modeling API & Services Finalization Task Forces (FTFs). Note, however, that these resolutions must be considered preliminary until the FTFs complete and their reports are approved by the OMG. The KerML specification has not been updated in this release.
Resolutions to the following issues are included in this release. The subclauses of each document affected by a resolution are tagged in the document with the corresponding issue key and title. In addition, the doc/changes directory includes PDF cumulative comparison documents between the Beta 2.3 and published Beta 2 versions of the specification documents.
KerML Specification
None.
