Founder and main researcher of WESO (Web Semantics Oviedo) research group, which collaborates with different companies around the world applying semantic web technologies to solve practical problems. The development of data portals for several companies and public administrations led to his interest on RDF validation. Member of the W3C Data Shapes working group and of three W3C community groups: Shape Expressions, SHACL and RAX (RDF and XML interoperability). Chairman of the Best practices of Multilingual Linked Open Data community group. He implemented the SHACL and ShEx library Shaclex and maintains an online RDF validator service. He has also written an introductory book about Semantic Web in Spanish. Eric is the W3C staff contact for the Health Care and Life Sciences Interest Group, RDF Data Shapes (RDF Validation), LDP, RDF 1.1, SPARQL 1.1, RDB2RDF, SPARQL 1.0, SAWSDL and XML Protocol Working Groups. He has developed and designed multiple languages, including a significant contribution to SPARQL and ShEx. He developed the Javascript ShEx library to promote understanding about and exploitation of Shape Expressions. Iovka is an Associate Professor at University of Lille, France, and member of the Links research project affiliated to Inria - Lille Nord Europe and CRIStAL (Centre de Recherche en Informatique, Signal et Automatique).
