iVuBlender: a tool for merging incomplete and inconsistent views

View merging is an important activity in any conceptual modeling language. It is often desirable to combine a set of views to gain a unified perspective, to test hypotheses about how views are related, or to perform various types of analysis. A major challenge for view merging is toleration of incompleteness and inconsistency: views may be inconclusive, and may have conflicts over the concepts being modeled or how they are structured. Drawing on the theory developed in our earlier work (2003), we present a view merging tool, called iVuBlender, that allows for explicit modeling of incompleteness and inconsistency and provides a framework for interconnecting and merging incomplete and inconsistent views.
