XIS is a R&D project which mission is to analyze, develop and evaluate mechanisms and tools to produce information systems from a more efficient and productive way than it is done currently. XIS project is influenced by MDA reference model, and is mainly based on three principles: it is based on high-level models specification; it is based on generative programming techniques; and it is component-based architecture-centric. XIS is not a conceptual research plan, it is a working on project with concrete results and produced systems. In this paper we overview the XIS project by introducing its main elements, such as the XIS approach; XIS platform; XIS/UML profile; and XIS/XML language. Finally, we present the main conclusions and the work that will be handled in the near future.
