  In recent years, there is growing interest in the ways the European aviation
industry can leverage the multi-source data fusion towards augmented domain
intelligence. However, privacy, legal and organisational policies together with
technical limitations, hinder data sharing and, thus, its benefits. The current
paper presents the ICARUS data policy and assets brokerage framework, which
aims to (a) formalise the data attributes and qualities that affect how
aviation data assets can be shared and handled subsequently to their
acquisition, including licenses, IPR, characterisation of sensitivity and
privacy risks, and (b) enable the creation of machine-processable data
contracts for the aviation industry. This involves expressing contractual terms
pertaining to data trading agreements into a machine-processable language and
supporting the diverse interactions among stakeholders in aviation data sharing
scenarios through a trusted and robust system based on the Ethereum platform.
