Recent Developments in OCL and Textual Modelling

Workshop in OCL and Textual Modelling - Report on Recent Trends and Panel Discussions

This paper reports on the panel session of the 17th Workshop in OCL and Textual Modelling, As in previous years, the panel session featured several lightning talks for presenting recent developments and open questions in the area of OCL and textual modelling. During this session, the OCL community discussed, stimulated through short presentations by OCL experts, proposals for improving OCL to i...

Integrating OCL and Textual Modelling Languages

In the past years, many OCL tools achieved a transition of OCL from a language meant to constrain UML models to a universal constraint language applied to various modelling and metamodelling languages. However, OCL users still experience a discrepancy between the now highly extensible parsing and evaluation backend of OCL tools and the lack of appropriate frontend tooling like advanced OCL edit...

Using an OCL Impact Analysis Algorithm for View-Based Textual Modelling

The Object Constraint Language (OCL) has become a vital part of many frameworks, tools and languages within model-driven engineering. One such application of OCL is the use for describing rules in concrete syntax definitions. Within the textual modeling framework FURCAS, OCL is extensively used for the definition of lookup and attribution rules. Based on these rules the model which is described...

Applying Query by Example in OCL for Platform-independent Programming

Precise modelling of behaviour is an area where programming meets modelling, and textual syntax competes with a visual one. By developing a UML based platform-independent framework, we aimed to find a visual syntax aid to make the language more approachable to stakeholders, while taking advantage of existing UML syntax intuitions and offering a truly higher level of abstraction. Our solution co...
