Proposed model for global SWIM governance

Abstract

System Wide Information Management (SWIM) is a concept implemented by multiple Air Navigation Service Providers (ANSPs) to provide efficient access to systems, services, and data used for their operations. Global SWIM utilizes identical concepts, but instead focuses on the connectivity between ANSPs instead of systems and services within an ANSP [1]. A successful Global SWIM implementation enables interconnectivity between the SWIM networks of multiple ANSPs utilizing one or more GEMS (Global Enterprise Messaging Service) providers. In order to exchange flight, weather, and aeronautical information efficiently, the GEMS providers must adapt between each ANSP's local SWIM infrastructures [2, 3]. Providing end-to-end connectivity between authoritative sources of information (ANSPs, airlines, etc.) requires multifaceted adaptation of both a technical and procedural nature. During the Mini Global II demonstration, four industry partners (Harris Corporation, Mosaic ATM, NEC Corporation, and Indra Sistemas) each developed a Global SWIM Service that interconnected, forming an interoperable network providing users with access to information produced by multiple ANSPs through a single interface. During the development of these Global SWIM Services, it was necessary to utilize common messaging standards, such as AMQP, SOAP and REST, and common data standards, such as the Aeronautical Information Exchange Model (AIXM) [4], Weather Information Exchange Model (WXXM) [5], and Flight Information Exchange Model (FIXM) [6] to enable basic message exchange to ensure interoperability between the GEMS providers. However, it was found that an additional layer of interoperability is needed to bridge the differences in governance models used by each ANSP. The additional layer of interoperability will enable GEMS providers to adhere to the governance policies of the ANSPs and organizations connected to their service, and communicate these policies to other GEMS providers. The goal of this paper is to outline a framework for encoding the governance policies of multiple ANSPs for enforcement across multiple GEMS providers.
