This tutorial describes the motivation for semantic integration of data, its difficulties, the related requirements and tasks, the main approaches for integration, and then it focuses on case studies of marine data coming from the ongoing BlueBRIDGE project as well as from previous projects in the same area (the completed EU research infrastructure project iMarine). A process for constructing semantic warehouses of marine data is introduced, a process that comprises various steps including ontology-engineering, schema mapping, entity matching, provenance management, and quality testing. Finally, the it discusses the exploitation of such semantic warehouses, as well as future steps and open challenges.
