DataWeek 2023 served as an excellent platform for engaging discussions with other projects in the field, including EXAMODE, VasselAI, DAPHNE, and SELMA. We explored potential areas of collaboration, including the organization of joint events, knowledge transfer, and lessons learned events between the projects. Additionally, we discussed the establishment of a list of experts who can act as evaluators and advisory board members for the other projects.

One of the key topics that emerged during the conference was the ecological footprint of Big Data infrastructures and technologies. As the use of extreme-scale analytics expands, the overall carbon footprint is set to increase. This is a significant perspective that we, at MARVEL, are keen to address. We are committed to reducing this footprint by promoting more computations at the edge and fog, thereby reducing the communicational effort and the overburden of a data center in the cloud. Our algorithms and data processing procedures are designed with efficiency in mind, and our results can be utilized to improve the ecological footprint of a smart city.
