ASHIN project's work package WP6, "Social innovation and standardization" aims to determine future trajectories of ASHVIN-developed innovations, including standardisation triggering standards to be applied by the market in connection with deploying new innovative privacy-focused practices within the industry. These will enable the project results to be widely used afterwards, thus ensuring a sustainable impact of the project in the long run. Deliverable 6.6 entitled Availability Of Measured Maintenance Data Of Infrastructure For Public Domain" is developed under this work package. Abstract This deliverable concerns the theoretical grounding of open data efforts for maintenance data of public infrastructure, as well as reports of ASHVIN practices in this regard. It also provides a framework and recommendations that can be applied to other kinds of public data and describes the exemplary implementation of these recommendations in the ASHVIN Zadar Airport demonstration case. It provides a hierarchical structure for maintenance data availability and a set of five ADAPT principles that guide data availability decisions and implementation.
