The idea of collaborative business intelligence is to extend the decision-making process beyond the company boundaries thanks to cooperation and data sharing with other companies and organizations. In this direction, we propose a query reformulation framework based on a P2P network of heterogeneous peers, each exposing OLAP query answer- ing functionalities aimed at sharing business information. In our frame- work, an OLAP query expressed on a peer is reformulated on other peers by relying on a set of mappings between the multidimensional schemata of peers. In this extended abstract we sketch the user interaction scenario we envision and briefly discuss each phase of the reformulation process.
