|The interoperability of critical infrastructures, such as ports, has become a primary concern of EU in recent years. Information systems that have the control of these infrastructures are continuously evolving and handle heterogeneous collections of data, processes, and people. Moreover, cross-infrastructure dependencies may give rise to cascading and escalating data model discrepancies across interconnected systems. In this article, we present a data model -following the newest technology standards- that tries to consolidate APIs and services of highly complex infrastructures. Port environments are a characteristic example of them, since massive amount of data and services from different sources are processed and used. We adopt a bottom-up approach, considering every service interconnection as an independent entity, which must be aligned with the proposed common vocabulary and data model. The strict guidelines that are injected into the lifecycle of a service/component development, lead to explicitly enforce interoperability between each one service that lives inside the ecosystem of the port. That is -and should be- a step towards “the cognitive port of the future”, where developers, SMEs and huge vendors can exchange and reuse data from a shared repository. Consequently, ports will play key role in the new information system model, as in-house marketplaces will be developed, for companies to disseminate and exploit their data and services.|
