Carsten Keßler

I am a post-doc researcher at Institute for Geoinformatics (ifgi), University of Münster. My current position is in the semantic interoperability lab (MUSIL), where I coordinate the university`s Linked Data initiative (LODUM). I am also consulting the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) in the Humanitarian eXchange Language (HXL) project.

It's completely okay to spell my last name Kessler if there's no ß on your keyboard. By the way: It also pronounces like a double s, not like a b.
