Model-driven spreadsheets in a multi-user environment

The main goal of our work is to develop a framework for model-driven and distributed collaboration in complex spreadsheet ecosystems. Indeed, in a computing world that is growingly distributed, the process of elaborating spreadsheets is often performed in a collaborative way, by many actors. In a model-driven environment, this means that one model must have many instances, one for each of the actors involved. Later, instances may be evolved independently and synchronization techniques are needed to evolve the original model so that conformity is restored.
