12 and 13 February 20014 we've been in Luxembourg in the Euroforum Building for our M12 first review on the JUNIPER project. We reviewed the work accomplished in the first 14 months of the project in building the JUNIPER big data realtime platform. In particular we presented our state of the art of big data storing and modelling tools, and our language for modelling real time big data systems. This review was an occasion to get very useful feedback from our reviewers. This feedback will be the bases of the work to be accomplished on the second year, in which we'll work on modelling big data structures and on delivering a first version of our big data realtime systems modelling environment.
