The Work Package 4 is responsible for adding value to the data produced within the UNO Project. To do this, the target is to organize the data within a relational database, which facilitates its use and can allow the sharing of data with the national and international scientific community. In the current scientific context, in which topics such as "open science", “open access” and "big data" have become central, this aspect is of great importance. The WP4, coordinated by Marina Bisson (INGV, Pisa Section), is now finalizing the analysis document, while the first elements of the database are being built on the server designated for this purpose. Good luck !
