The Smart Cities Marketplace community is organised in a series of Action Clusters, that themselves have organised subgroups called Initiatives. Each Action Cluster represents assembly of partners committing to work on a specific issue related to smart cities, by sharing the knowledge and expertise with their peers.
An overview of Action Clusters and their Initiatives can be found here. Should you wish to join the community, it is recommended to take note of the Smart Cities Marketplace Charter, that sets out the guiding principles for participation. If you have found an Action cluster or Initiative that you believe you can contribute to and you subscribe to the Charter, do contact its management team.
