#ocl — Public Fediverse posts

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

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.

🔗 Try it out: https://editor.besser-pearl.org/

Some key features:

✅#Graphical modelling: Design models with an intuitive graphical notation.
✅Cloud Storage: #Store your diagrams online for easy access from anywhere
✅Real-time #collaboration: Work seamlessly with multiple users on the same model.
✅#CodeGeneration: Automatically generate code for various technologies (e.g., databases).
✅#OCL Integration: Define OCL constraints with of our B-OCL tool
✅#Supports model import/export in B-UML and #JSON formats

Learn more about #OCL support in BESSER and how you can add constraints to your class diagrams. Even as part of our web modeling editor (with the option to #check their syntactic correctness) 🤯🤯

We did a software experiment today 👨‍🔬🧪⚗️

I gathered 11 people to test during 2h our #lowcode platform BESSER as part of a #user #study.

During these 2h they had to "play" with the tool. They could #test any aspect of the tool (the #code generators, the web modeling #editor , the #OCL interpreter,...) and report all the issues (bugs but also feaures they felt were missing).

This was also a way to make sure everybody gained some experience with the tooling as some were only familiar with specific components.

I'm very happy with the result. We all learned a lot about what people expected from the tool. And as a result, we opened #70 new #issues 👏👏👏

Our next 🧪⚗️ will be to see how many of these 70 can be automatically fixed with an #AI #assistant 🤔. We'll first a triaging of those that are #goodfirstissues and start with those.

Later, we'll repeat the experience with the BESSER Agentic Framework

And, honestly, if you're developing a tool, try it with yours. I really think it's one of the actions with better #ROI you could do

and Armen Sulejmani and Iván Alfonso for animating the session

Create #models and #OCL constraints on your web browser. #Validate them and generate a full #django application from them (or #SQL or an #API or #Python classes or... ) and deploy them with #dockercompose.

What else could you wish for??

https://besser.readthedocs.io/en/latest/releases/v2/v2.2.0.html

🍾🍾There's a new #OCL interpreter in town!🍾🍾

With it, you'll be able to evaluate OCL expressions over a system snapshot 🤯🤯

🎂 🎂 Today is my 1st #LISTAnniversary 🎉 🎉

One year ago, I started alone building the next generation of #intelligent #lowcode #platforms for #smart #software systems as part of the #BESSER project.

Given my limited programming skills 😅, it's good that now we're a team of 12 pushing this goal. Expect a major release of the main #lowcode platform very soon with #OCL support, #UI modeling, #REST #API generation ... 👀👀

And as always 💯 #opensource #openaccess #openscience

Having already tooted , I’ve decided I need to pay more attention to #Hastags . So here# we go with #introduction . I’m an #eyfs teacher now an #eyfstooters and interested in #childdevelopment #childrensbooks and #outdoorplay . I enjoy #reading and #history and have many connections with the #equine world . Any teachers from #OCL here? I have strong opinions about many things but am always willing to listen to different views .
