The talk introduces an algorithm for inverting R2RML mappings via SPARQL and reports initial results against the W3C R2RML test suite, but its main focus is on the open questions that inversion raises. https://w3id.org/np/RANzxo3YntrdSv5gLdAmaI0S8BIctwjyN11sSAvii9ZL0/presentation http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://www.wikidata.org/entity/Q604733 https://w3id.org/np/RANzxo3YntrdSv5gLdAmaI0S8BIctwjyN11sSAvii9ZL0/presentation http://www.w3.org/2000/01/rdf-schema#label Presentation of "Let's Invert It!
