Commission Implementing Regulation (EU) No 716/2014 of 27 June 2014 on the establishment of the Pilot Common Project (PCP IR) identified a set of ATM functionalities to be deployed, enabled by Initial System Wide Information Management (iSWIM).
The goal of iSWIM is to foster the interoperability between European ATM Stakeholders in a networked environment. The means to achieve this goal are information services and service orientation practice whereby information services are identified, designed, described, and implemented (provider and consumer side).
The EUROCONTROL Specification for SWIM Service Description contains requirements for describing information services in the context of iSWIM. The requirements prescribe the minimum set of elements a service description has to contain.
