Metadata, standards and ontologies are common ways of providing data with context, structure and meaning. In this webinar Sira explores the idea of once data are ontologised (mapped to standard structured vocabulary), they become linkable to build a bigger infrastructure of knowledge network and provides a few scientific examples of how knowledge are drawn from linked data. She also provides a brief overview of tools that can be used to give data context, structure and meaning at different stages of the data lifecycle.
