Semi-automatic model integration using matching transformations and weaving models

... heart of model driven engineering (MDE) and can be used in many different application scenarios. For instance, model transformations ... that automates the development of model transformations. In this paper we propose a novel approach that uses matching transformations ...

Inverting Schema Mappings

... of interest arises when S is the class of all instances, in which case an S-inverse is a global inverse. We focus on the important ... we show how to construct an S-inverse when one exists. In particular, we show how to construct a global inverse when one exists. ...

An Algebraic Framework for Merging Incomplete and Inconsistent Views

... merging, also called view integration, is a key problem in conceptual modeling. Large models are often constructed and accessed by ... sources and to the merge assumptions related to them. In this paper, we present a framework for merging incomplete and inconsistent ...

Unified Class Evolution by Object-Oriented Views
