The complexity of Big Data technologies and the variety of competences required to design applications relying on them has emphasized the relevance of systems for managing and documenting Big Data architectures. Documentation, reconfiguration, and verification are for example crucial tasks for a solid design of technological solutions but are not easily supported in the current landscape of Big Data technologies. Rethinking data and information management in the context of Big Data technologies is then a primary goal for future research.

Methods, principles, and perspectives developed by the Data Semantics community can significantly contribute to this goal. Solutions for integrating and querying schema-less data, for example, have received much attention. Standards for metadata management have been proposed to improve data integration among silos and to make data more discoverable and accessible through heterogeneous infrastructures. A further level of application of Data Semantics principles into Big Data technologies involves Representing Processes, i.e. representing the entire pipeline of technologies connected to achieve a specific solution and make this representation shareable and verifiable to support a mature implementation of the Big Data production cycle.

The symposium will bring together leading researchers, engineers, and scientists from around the world.
