You can now generate #web #apps that embed (some) of the #OCL constraints defined at the model level to guarantee the #quality of the data

@stargirl has simplified the Open Community License (OCL) from Prusa

We keep improving our #OCL #parser and #evaluator, e.g. https://github.com/BESSER-PEARL/BESSER/issues/367#event-21642067463

Keep reporting your issues!

🚨MAJOR RELEASE ALERT 🚨
Today we are launching BESSER v.4, with some massive improvements 👏🥳🎉:
✅ Project management: create new #modeling projects comprising different types of diagrams (#classdiagram, #statemachine, #objectdiagram...) in our #online #modeling #editor
✅Create object diagrams to model specific scenarios conforming to your class diagram
✅ #Evaluate #ocl constraints on your object diagram and get #feedback on whether your scenarios are #valid
✅ Plus many other improvements: #fluentapi, #rdf generation,...

I was manually looking for #OCL #courses (via a classical Google search, yes, some of us still do it from time to time) to complement the info we got from our hashtag#teaching #ocl online form ⬇️

📋https://modeling-languages.com/teaching-ocl/ You still have the time to fill it! ✍️

And my overall impression is that:

❌ Very few institutions teach OCL.
❌ Even worse, I feel there are less and less. Indeed, when searching online, I get quite a lot of old results from courses that were offered at some point (many around 15-20 years ago) but have since then disappeared (I guess replaced by, among others, sexier AI related topics).
❌ The tooling situation is one of the key factors (as reported also in the comments of the post linked above).
✅ I'm hoping that our online OCL tool (see https://github.com/BESSER-PEARL/B-OCL-Interpreter, led by Fitash Ul Haq, PhD and now part of our #web #modeling #editor https://editor.besser-pearl.org/ ) and free #tutorials can be useful if any of you wants to give OCL a second chance.

Because if not OCL, then what? 🤔

Model class diagrams and generate code from your web-browser. No need to install anything.
