SysML v2 Requirements Review and RFP Status.Since the Brussels meeting the week of June 5, the SysML v2 Requirements were reviewed extensively and updated based on the feedback. The first review was an internal review by the Working Group, and the second review was distributed to approximately 25 representative organizations for their review and feedback. The updated SysML v2 Requirements Support Document is posted on the SysML v2 Requirements Review page. This document contains the requirements and additional background and context information for the requirements.
Since the last meeting in Brussels, it was decided to split the requirements into 2 separate RFP’s called the SysML v2 RFP and the SysML v2 API & Services RFP. The drafts for these 2 RFP’s were posted to the OMG site. The OMG document numbers for these documents and 2 accompanying spreadsheets are:

Draft SysML v2 RFP Presentation to ADTF. Sandy and Ed Seidewitz presented an overview of the draft SysML v2 RFP and the draft SysML v2 API and Services RFP to the ADTF on Wednesday, September 27. (omg document number ad/2017-09-06). This was a 2-hour presentation that provided a general overview of the RFP’s, and additional detail on the language architecture requirements which were thought to be of specific interest to the ADTF. Pete Rivett raised some questions that were brought later in the week to the Architecture Board for further discussion.
The particular concern that Pete raised was whether SysML v2 is intended to leverage existing OMG technologies such as MOF. Ed and Sandy were invited to the Architecture Board on Thursday afternoon to discuss this further. Ed provided the justification for some of the language architecture requirements, which were originally formulated by the SysML v2 Formalism Working Group. The follow-up actions were to provide the Draft RFP numbers to the AB for their further review, and to provide the driving needs that drove these requirements.
Presentation of SysML v2 Language Concepts.On Tuesday afternoon,Sandy provided an overview of the language concepts that are reflected in the requirements in the SysML v2 RFP. The concepts are part of the Systems Engineering Concept Model (SECM), and are summarized in section 6.2.2 of the SysML v2 RFP, and in section 3.1.2 of the SysML v2 Requirements Support Document.
SysML v2 Submission Team General Planning. Ed Seidewitzled the Thursday morning session to present an open proposal for a submission approach that emphasizes incremental releases to mitigate risk. This presentation is available on the New Orleans meeting page.
Proposed SysML v2 Metamodel Approach.Chas Gayley presented a proposed SysML v2 metamodel approach called KerML. Chas, Conrad Bock, Bjorn Cole, and others have been working on this approach for the last couple of years. They are in the process of evaluating how the approach can satisfy the SysML v2 RFP requirements. Chas’s presentation is available on the New Orleans meeting page.
A few key aspects of the approach include:
- A small core metamodel is defined at the M2 level. The model libraries at the M1 level extend these concepts and specify the semantics for the domain concepts. This enables the domain concepts to be more easily extended.
- Common patterns are used to specify behavior and structure. This helps to ensure more integration.
