Enhancing interoperability in cross-platform enterprise mashups through data aggregation and extraction

Enterprise Mashups usually comprise services from different service domains that often differ vastly from each other regarding their protocols, data or programming models. This fact poses a challenge especially for non-professional developers who want to quickly create a complex service composition because they are required to know the technical details of the involved service domains in order to use them in their composite application. In this paper we describe an extensible framework that allows for enhanced interoperability of arbitrary service types by introducing a unified way to interact with disparate Web services and an intuitive model for handling heterogeneous data types within a composition. Our framework forms the basis for building extensive tool support for end-users that allows easy creation of Mashups with diversified services, collaboration with other users and distributed execution of a service composition.
