This video was recorded during the International Summer School for Data FAIRness in Environmental & Earth Science Infrastructures, hosted by LifeWatch ERIC in July 2019. In recent years, one of the major challenges in Environmental and Earth Science has been managing and searching larger volumes of data, collected across multiple disciplines. Many different standards, approaches, and tools have been developed to support the phases of the Data Lifecycle (Data Acquisition, Data Curation, Data Publishing, Data Processing and Data Use). In particular, modern semantic technologies provide a promising way to properly describe and interrelate different data sources in ways that reduce barriers to data discovery, integration, and exchange among biodiversity and ecosystem resources and researchers.
