Information for xtUML Days 2020 is available here.

BridgePoint is Open Source Software (OSS). It is free. However, OSS is not free like “free beer”; it is more like “free puppy”. Just like a puppy, open source software requires care and maintenance. Some members of the xtUML Community contribute to BridgePoint by finding and fixing bugs, writing code for new features or helping to write documentation.

Other members of the community fund these activities. Usually, it is a company running a project that employs BridgePoint tooling in their development processes.

One such project is active in May of 2020. The project is name Panda. The specification is also open source. Please see it here and follow along with the progress of the project.

xtUML Days joined forces with MODELS’18 to provide an opportunity to mingle the communities.

Here are all of the presentations (that could be released):

• Day 1 Flyer (agenda)
• Shlaer-Mellor xtUML Overview
• Shlaer-Mellor OOA Original Overhead Transparency Intro
• Big Machine Big Model – Modeling Industrial Machinery
• 1-3-5 Application, Dialects, Architectures
• Constraint Modeling with Albert Einstein
• xtUML at Shinshu University
• Roving in xtUML
• 10 Steps to a BridgePoint Enhancement
• Day 2 Flyer (agenda)
• “Show and Tell” – updates since xtUML Days 2017
• Deployment Modeling
• Work in Progress
• Roadmap Possibilities

Thank you to all of the presenters able to release their presentations to the community.

xtUML Days 2018 is co-located with MODELS in Copenhagen in October.  MODELS is increasing its focus on Industrial Modeling while maintaining the academic and research strength of the conference.  The graphic highlights the different industrial opportunities at MODELS this year.

Nenad Ukic (Neno) of Split, Croatia published a PhD thesis that has one of the most clear and concise overviews of xtUML I have read.  So, even if you are not interested in complexity metrics, this paper is worth reading!

Presentations from xtUML Day 2017 Linköping

This episode of xtUML Day was the best ever.  We stepped up from one day to two full days.  The venue was stunning.  The guest list included virtually all of the current key players in the Method.

Here are all of the presentations (that could be released):

• xtUML 2017 Linköping Flyer (agenda)
• Saab – Modeling at Saab
• Bounding Class Extents Using Constraint Programming
• Proposed xtUML Type System
• Type System with Abstraction
• BridgePoint Features
• Channel Modeling
• Long Term Support (LTS)
• Type System Background and Discussion
• Roadmap Possibilities
• User Experience and User Interface

Thank you to all of the presenters able to release their presentations to the community.

Self-driving cars pose challenges to testing. The quantity and magnitude of sensor inputs create an enormous test vector space. Traditional manual testing methods are inadequate to cover this multi-dimensional vector space with test cases.
To address this challenge model-based techniques are applied to manage the testing complexity. Abstraction and automation increase the productivity of test engineering. Model-based test engineering allows generation of test cases, test data and predicted behavior. Sensor test generation, automated Navigation testing and turbulence induced testing are elements of a strategy to improve the efficiency of testing for self-driving cars.
A case study is provided as an example. Conclusions are then summarized.

xtUML 2015 is a two day summit in Indiana this coming December. The event will cover xtUML methodology as well as open-source BridgePoint development. It will be a great opportunity to meet and learn with other xtUML modelers and developers.
