Delta-P: Model comparison using semantic web standards

The Delta-P approach relies on Semantic Web notations and techniques to perform comparison of potentially complex models. The key feature of the approach is to allow for flexible adaptation, by using queries to detect changes relevant to different schemata. Although the approach was originally oriented to software process models, in this paper we concentrate on its potential applications to other types of models (e.g., UML). We briefly describe the approach and its initial implementation (Evolyzer) and discuss the direction of our future work.
