In the current society, logistics is faced with at least two big challenges. The first challenge considers safety and security measurements dealing with terrorism, smuggling, and related security accidents with a high societal impact. The second challenge is to meet sustainability requirements implying optimal use of resources and physical infrastructure. A condition sine qua non for dealing with these challenges is the realization of a flexible platform for sustainable and secure data exchange between collaborating global supply chain actors. This paper presents such a platform. It allows shippers, authorities, logistic service providers, and carriers to be fully interoperable across closed communities, to perform paperless logistics, and to adhere to societal demands of security, safety, and sustainability. Its functionality is derived from similar approaches as have been applied in modern social media. The paper elaborates on the functionality of the platform and its implications for research. It builds upon the research and innovation work as currently done within the EU FP7 Cassandra and iCargo projects.
