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.

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). She has been working on expressive languages for describing and querying tree-structured data, and more recently on data exchange for relational and graph data. She was a member of the W3C RDF Data Shapes Working Group and is a member of the W3C Shape Expressions community group. She has developed the theoretical foundations of the Shape Expressions Language. Dimitris is a Knowledge Engineer and Semantic Web researcher at the University of Leipzig and the DBpedia Association.
