Ontology-driven software development has gained significant interest in domain-specific application development. Ontologies are treated as formal models representing knowledge, which can be used for automatic code generation. Among existing technologies, Eclipse Modeling Framework (EMF) has been widely used to generate domain-specific metamodels and Java code using Ecore. Such robust technologi...

Model-based techniques are in wide-spread use for the design and implementation of domain specific languages (DSLs) and their tooling. The Eclipse Modeling Framework (EMF) is a frequently used environment for model-based language engineering. With its underlying modelling language Ecore, its XML serialisation support and its versatile extensibility it provides a solid grounding for many task-sp...

When designing complex domain-specific languages, metamodels are frequently enriched with derived features that correspond to attribute values or references (edges) representing computed information in the model. In the popular Eclipse Modeling Framework, these are typically implemented as imperative Java code. In the paper, we propose to integrate the EMF-IncQuery model query framework to the ...

Das Eclipse Modeling Framework (EMF) ist ein weit verbreitetes Rahmenwerk zur modellgetriebenen Softwareentwicklung. Mit EMF lassen sich strukturelle Modelle als Instanzen des Ecore-Metamodells erstellen. Aus einem Modell lässt sich Code erzeugen, der im Falle benutzerdefinierter Operationen jedoch lediglich leere Methodenrümpfe enthält. Das von uns entwickelte Werkzeug ModGraph erweitert EMF u...

Model-driven software engineering aims at increasing productivity by developing high-level executable models. The Eclipse Modeling Framework (EMF) significantly contributes toward this goal. Unfortunately, EMF supports only structural models based on the Ecore metamodel. Recently, Xcore has been developed to extend EMF with behavioral modeling. To this end, Xcore provides a single textual langu...

Model-driven software engineering aims at increasing productivity by replacing conventional programming with the development of high-level executable models. However, current technology focuses on structural models, while behavioral modeling is still neglected. The transformation engine ModGraph intends to fill this gap. ModGraph complements the Eclipse Modeling Framework with graphical transfo...

Model driven software engineering aims at creating high level executable models which may be interpreted or compiled. For efficient execution of operations on model instances code generators play an important role. A wellestablished tool for structural modeling and code generation is the Eclipse Modeling Framework (EMF). We extended EMF by behavior modeling within ModGraph, a tool to model beha...

The Eclipse Modeling Framework (EMF) and its meta-meta model Ecore support uni-directional and bi-directional references. It is quite common that references are defined uni-directionally only because of saving storage space or separating meta models, which is problematic when implementing Object Constraint Language (OCL) constraints that require navigation against the direction of unidirectiona...

One of the main challenges of achieving interoperability using the HL7 V3 healthcare standard is the lack of clear definition and supporting tools for modeling, testing, and conformance checking. Currently, the knowledge defining the modeling is scattered around in MIF schemas, tools and specifications or simply with the domain experts. Modeling core HL7 concepts, constraints, and semantic rela...

Model Driven Software Development (MDSD) has matured over the last few years and is now becoming an established technology. As a consequence, dealing with evolving meta-models and the necessary migration activities of instances of this meta-model is becoming increasingly important. Approaches from database schema migration tackle a similar problem, but cannot be adapted easily to MDSD. This pap...
