Devika Madalli and ARD Prasad of the Indian Institute of Statistics invited me to give a lecture on the description of datasets using semantic vocabularies during the International Workshop on Open Data Repositories organized by DRTC, ISI-ICSU and CODATA on 1-3 March 2017.
Being a 45' lecture, I put together much of the material I had prepared for different occasions and added more details on why we need semantic dataset descriptions and up to which point vocabularies like DCAT, Data Cube and VOID can help us.
