Shlaer-Mellor Days 2022

What is this?

Shlaer-Mellor Days 2022 is a modeling conference and represents the 9th edition of Shlaer-Mellor Days (formerly known as xtUML Days). (See Previous xtUML Days.) Shlaer-Mellor Days is the most dense gathering of the year of Shlaer-Mellor modelers. The Shlaer-Mellor xtUML Community meets to collaborate on Modeling, Method and Tooling.

The central topic of the conference is end-to-end modeling, execution, translation and deployment of models-as-code in mission critical settings employing rigorous methodology. The unifying theme is practical, actual, industrial application modeling within production installations. Attendees will network with engineers, scientists and educators who understand executable and translatable modeling as applied in active systems.

In 2022, a special focus will be continued to extend and clarify the Shlaer-Mellor Method in light of undocumented developments over the last several years.

Also in focus:

  • Method advances (specifically convergence and rationalization of PT and K-C dialects)

  • Tooling Refinements

  • Incremental Adoption

  • Model Compilation

The Shlaer-Mellor Community is keen to exchange expertise and learn from one another. Shlaer-Mellor Days provides a forum for developers to share best practices and influence the direction of the technology. The conference committee hereby solicits compelling papers and presentations that exhibit method advances, tooling improvements and application experience in Shlaer-Mellor modeling and related Executable/Translatable modeling.

Presenters

Key Shlaer-Mellor community members planning to participate include Mike Lee, Paul Francis, Colin Carter, Ian Wilkie, Leon Starr, Marc Balcer, Levi Starrett and others.

In-Person Gatherings

A dinner gathering is planned in the UK in Cheltenham on the evening of 20 October 2022. The venue Bill’s at 19:30. Dinner is included in the conference registration (including a significant other).

A dinner gathering is planned in Sweden in Linköping on the evening of 25 October 2022. The venue and time are TBD.

Call for Papers (closed)

A program committee will review and select from submitted papers, posters and presentations. Selection is based upon perceived value to the Shlaer-Mellor Community.

Topics of interest to Shlaer-Mellor Days include but are not limited to the following:

  • real-world application modeling examples of installed systems

  • techniques of editing, verifying, translating, debugging and deploying models

  • methodology (Shlaer-Mellor) advances, extensions and refinements

  • static analysis of models and generated code

  • model-based model compilers

  • model integrity

  • action language dialects

  • target software architectures and translation onto those architectures

  • process integration of modeling and modeling tools

  • tooling supporting the Shlaer-Mellor Method

  • current state of the art editing, verification, translation, debugging

  • recent experience with tooling and BridgePoint in particular

  • techniques for educating modelers from young children to experienced professionals

  • tooling migration experience reports

Presentations are expected to be 10-30 minutes in duration with additional time for questions and discussion.

All submissions will be evaluated by the program committee. Selection is based upon significance, clarity and alignment with the call and value to the attendees of Shlaer-Mellor Days 2022. Submissions that promote discussion, advance the Method and generate interaction among Shlaer-Mellor Community members are most desired. For a presentation to be accepted, at least one of the authors must register for Shlaer-Mellor Days, present the material and participate in the conference.
