Big data processing is now widely employed in all aspects of our lives. Parts or copies of a huge amount of data are stored in separate locations, and is difficult to collect and process heterogeneous data in a centralized manner, as it would be exceedingly inefficient to transfer them over the network. We therefore need new software foundation based on which big data can be efficiently analyzed and shared in a distributed way.

This workshop aims at fostering discussion, exchange, and innovation in research and development in software foundations for data interoperability as well as the applications in real-world systems such as data markets. We invite not only people from the database community but also researchers and professionals from the areas of programming language, software engineering, distributed computing, artificial intelligence, and natural language processing to share their knowledge and experience.

For example, bidirectional transformation has been intensively studied in both database and programming language communities to address the view update problem, and a recent trend is to use bidirectional transformation for data sharing and data interoperability in P2P networks. In addition, many machine learning and natural language processing models have been utilized for data management, especially for data integration tasks. We thus hope to bring together academia and industry people in related areas for the discussion of challenges and technical solutions to software foundations of data interoperability.
