Model-Driven Analytics for Open Data APIs (including a heatmap UML model!)

Our tool is able to visualize how end-users interact with open data sources regarding two types of metrics: (1) performance metrics and (2) semantic metrics. Among them, we include a UML heatmap to highlight the part of the open data schema that is most frequently requested

Evolving Systems Paradigm – Product Line Engineering in Practice

System evolution is hard to manage unless done systematically. This is especially important in product line engineering. Our approach is a methodology to directly contain the risk of the “exponential rise in complexity” for rapidly evolving product lines.

A watermarking algorithm for models to protect your intellectual property

We propose the integration of digital watermarking techniques in the model-driven engineering development lifecycle as way to protect the intellectual property of your modeling artefacts in collaborative modeling scenarios

Discovery and Visualization of NoSQL Database Schemas

Most NoSQL database systems do not require the definition of schemas but this does not mean such schema does not (implicitly) exist. We have implemented a model-driven reverse engineering approach to infer such NoSQL implicit schemas

OpenAPItoUML: a Tool to Generate UML Models from OpenAPI Definitions

We present our new tool OpenAPItoUML to generate UML models from OpenAPI definitions, thus offering a better visualization of the data model and operations of REST APIs. OpenAPItoUML is available as an open source Eclipse plugin.

Telosys : the concept of lightweight model for code-generation

See how you can use Telosys as a “development accelerator” for your next project. Thanks to its pragmatic approach, it allows for a quick start of very different kinds of projects.

Harvesting and Reimagining Modelling Technology – 24 requirements for a modeling biotope

Clearly, the huge potential of modeling has not come to fruition yet. Read on to see why and what are the requirements we propose for a transformation of modeling technologies in a complete new ecosystem, called miotope

A Novel Scalable Modeling Ecosystem

Summary of our contributions towards a scalable query and transformation modeling framework able to handle very large models

Conceptual modelling for the rest of us with ConML

Modelling is a useful technique for shaping, exploring, documenting, understanding and communicating artefacts of many kinds, and not only software. ConML is a conceptual modelling language for non-experts in information technologies and especially suited to serve non-software modeling domains.

Distributing relational model transformation on MapReduce

Overcome the limitations of executing model transformations on large models by distributing them on top of a mapreduce infrastructure. We've done it for ATL. Read the full details on this paper accepted in the Journal of Systems and Software

Model-driven Development of OData Services

OData is a protocol to facilitate the publication and consumption of queryable and interoperable data-driven services. OData is based on the use of RESTful APIs derived from a data model. We present a model-driven approach to automate the generation of OData services from data sources

Model-IA: the future virtual assistant for programmers ( combining modeling and artificial intelligence)

Read about a new project between CEA List and Universitat Oberta de Catalunya on the integration of Artificial Intelligence in software development tools.

10 JavaScript libraries to draw your own diagrams (2018 edition)

A list of the best JavaScript drawing libraries we have found. With them you can easily bring your diagrams online!

Executable UML Tutorial 3: Domain Analysis (Part 2)

How to partition the system into a set of domain models and decide the best language for each domain. Plus the need to choose the model platform that best fits your project.

Over 65.000 views for the OCL tutorial slides

Slides and full chapter for our introductory tutorial to the OCL language, now with more than 65.000 views on slideshare

Quality Aspects in Model Driven Engineering (COMLAN Special Issue)

Our special issue on Quality in Model-Driven Engineering has now been finalized and published online in the Computer Languages, Systems & Structures journal linked to the  Quality Aspects in Model Driven Engineering track at QUATIC 2016

A Graph Solver for Automatically Generating Consistent Models

We report about a new model generator which automatically creates well-formed instance models that satisfy consistency constraints. Our model generator is based on a graph solver that natively operates over EMF-based (graph) models and combines advanced graph algorithms with rule-based exploration driven by traditional SAT solving techniques.

WEOD: International Workshop on Engineering Open Data

Have you ever thought how effective and practical use of open data might change our societies

Collaborative modelling with chatbots in social networks

Have you ever thought about using social networks and chatbots for collaborative modeling? Well, this is now possible. Read how you can built your models using natural language discussions on twitter and telegram
