Introduction to a new Executable UML Tutorial Series and Case Study

First in a new series of articles to take you step by step through the construction of a complete set of Executable UML (xUML) models. Presented with an initial set of fuzzy requirements, we will transform them into an unambiguous, detailed, constrained and executable statement of the desired system.

Text to UML tools – Fastest way to create your models

Sometimes the easiest way to draw a model is to "write" it down. These tools will render nicely looking UML diagrams from a few lines of text.

Smart bounded verification for UML / OCL models

Correctness of UML diagrams annotated with OCL constraints can be checked using bounded verification. We show an automatic technique to choose the best bounds

I will model your software for 5 USD

Well, I will NOT but Fiverr has plenty of people willing to take modeling gigs for as low as five dollars. Should I be happy that UML is getting popular enough to generate interest in Fiverr?

ZenUML makes drawing sequence diagrams easier and faster

A new textual UML tool (to generate graphical sequence diagrams from a textual DSL definition) is now in the market. How does it fare against PlantUML and other competitors?

The secret life of rules in Software Engineering

Summary of my invited talk at the RuleML+RR conference where I discussed why rules are not first-class citizens in software engineering and why this has to change to keep up with the demands of big data and open data.

From Models to code with no mysterious gaps – interview with Leon Starr

Leon Starr giving plenty of wisdom pearls on the benefits and optimal application of executable models while presenting his new book on the transition from models to code

OCL Monads – Functional Interpretation for the Object Constraint Language

The introduction of new functional-like features (like lambda expressions) in the OCL suggests a functional interpretation of the language as an optimal way to exploit such features.

UML to GraphQL (with some help from IFML)

Our approach to automatically generate GraphQL schemas from UML class diagrams (and IFML interaction models)

A UML Profile for OData Web APIs

Details of our UML Profile to model OData Web APIs. Once you have your UML model annotated with OData stereotypes you could automate the generation of your OData definition files.

iOCL: Write your OCL constraints interactively

iOCL is a new tool that helps you write OCL constraints faster and minimizing the chances you get them wrong thanks to its interactive mode

List of Executable UML tools (2017 update)

Complete list of executable UML tools for the fUML OMG standard and other UML executable languages

OCL Workshop 2017 – Recent developments in OCL and Textual Modeling

The meeting place for all kinds of discussions and new proposals around the world of OCL and textual modeling languages

The best UML book (and you didn’t even know it existed)

Allow me to explain why this book is the best UML book you will find. You can thank me later.

An ecosystem of tools around PlantUML to render textual UML diagrams anywhere you want (updated)

Check the growing ecosystem around PlantUML, a textual UML tool to easily create and embed graphical UML diagrams wherever you need them.

Interview with Francis Bordeleau on Papyrus, “the” modeling platform in Eclipse

Learn more about the past, present and future of Papyrus and the industry of software /systems modeling in general.

Viewing Java code as a live model

What if you want to check something on your Java code that requires “understanding” Java? Your IDE may fail you but this live Java model will help

Chart Mage – Fast drawing of UML sequence diagrams with textual autocomplete

A new textual UML tool that allows you to quickly define sequence diagrams online thanks to its autocomplete feature able to guess what UML keywords you're going to write next

Lucidchart – an online modeling tool that just raised 36 million dollars

After their investment round, we catch up with Lucidchart's COO to see what we can expect from the Ludichart web-based modeling tool in the future

A benchmark for OCL tools

I believe as a community we need to have mature UML and OCL benchmarks to help us evaluate, test and compare modeling tools. Do you agree?
