Towards a semantic infrastructure supporting model-based tool integration. GaMMa '06

With the rise of model-driven software development, more and more development tasks are being performed on models. Seamless exchange of models among different modeling tools increasingly becomes a crucial prerequisite for effective software development processes. Due to lack of interoperability, however, it is often difficult to use tools in combination, thus the potential of model-driven software development cannot be fully utilized. To tackle this problem, we propose ModelCVS, a system aiming at model-based tool integration. ModelCVS enables transparent transformation of models between different tools ’ languages and exchange formats, as well as versioning exploiting the rich syntax and semantics of models, thus going beyond existing low-level model transformation approaches. For this, ModelCVS utilizes semantic technologies in terms of ontologies and supports different integration patterns at the metamodel level. To foster reuse, a knowledge base captures essential information relevant for tool integration

Integrating Heterogeneous Tourism Information in TIScover - The MIRO-Web Approach

. A broad spectrum of tourism information is already distributed over various web sites. However, a major problem for the tourist is to find these web sites and to deal with the differences concerning information presentation and information access. At the same time, it is not feasible to store every kind of information a tourist might be interested in at one web site neither in terms of storage costs nor and even more important in terms of maintenance overhead. Therefore, in the course of the ESPRIT project MIRO-Web the official Austrian tourism information and booking system TIScover is extended in order to federate multiple structured and semi-structured tourism information sources on the web. In particular, MIRO-Web supports a homogeneous view on these heterogeneous sources which can be either materialized or defined as virtual. On the basis of this view, appropriate query mechanisms as well as a web-based interface provide the user with a single point of access. 1 Int..
