This document summarizes a webinar about BDVA i-Spaces, which are data innovation spaces that foster data-driven innovation. The webinar discussed what i-Spaces are, their value in collaborating and connecting to other initiatives, and the process for obtaining an i-Space label. Experiences from several labelled i-Spaces were also shared. The goal of i-Spaces is to establish a network across Europe for testing, piloting and exploiting big data technologies and applications through technical and business support services. Obtaining the i-Space label recognizes quality and impacts spaces that connect existing initiatives and promote data-driven innovation.
