I am Digital Publishing Activity Lead at the World Wide Web Consortium (W3C). I am also member of IW3C2 (International World Wide Web Conference Committee) , the committee coordinating the yearly World Wide Web conference series.
As part of my work, I also participate in lots of outreach activities, and I regularly make presentations, tutorials, etc. You can consult my list of presentations for further details.
I graduated as mathematician at the Eötvös Loránd University of Budapest, Hungary, in 1979. After a brief scholarship at the Université Paris VI I joined the Hungarian research institute in computer science (SZTAKI) where I worked for 6 years (and turned into a computer scientist…). I left Hungary in 1986 and, after a few years in industry in Munich, Germany, I joined the Centre for Mathematics and Computer Sciences (CWI) in Amsterdam where I have a tenure position since 1988. I received a PhD degree in Computer Science in 1990 at the University of Leiden, in the Netherlands. I joined the W3C Team as Head of W3C Offices in January 2001 while maintaining my position at CWI. I served as Head of Offices until June 2006, then as Semantic Web Activity Lead until December 2013. Since June of 2013, I am Digital Publishing Activity Lead.
Before joining W3C I worked in quite different areas (distributed and dataflow programming, language design, system programming), but I spend most of my research years in computer graphics and information visualization. I also participated in various graphics related ISO standardization activities and software developments. My separate “professional” home page contains a list of my publications, my public presentations, and details of the various projects I participated in the past. There is also a dblp entry for my publication generated automatically (although I am not sure it is complete…). (B.t.w., based on my publications, my Erdős number is ≤4…)
In my previous life (i.e., before joining W3C…) I was member of the Executive Committee of the Eurographics Association for 15 years, and I was vice-chair of the Association between 2000 and 2002. Between autumn 2007 and 2014 I was also member of SWSA (Semantic Web Science Association), the committee responsible for the International Semantic Web Conferences series. I was the co-chair of the 9th World Wide Web Conference, in Amsterdam, May 2000; since then, I have also been member of IW3C2 (International World Wide Web Conference Committee), responsible for the World Wide Web Conference series.
I have also developed some software (in Python) that might be of interest. An example is an SPARQL 1.0 API, a (partial) implementation on the top the RDFLib package. This package has then been added to RDFLib with a proper SPARQL language parser contributed by the community. I have also developed (and still maintain) a RDFa Distiller service, ie, a Python implementation of RDFa 1.1, a similar tool for the conversion of microdata to RDF. The RDFa and Microdata packages (both are also available on github) are also part of the core RDFLib package as parser plugins. I also developed a small package to interface SPARQL queries from Python; this software has been moved to sourceforge, and is effectively maintained by Sergio Fernández and Carlos Tejo Alonso (CTIC, Spain). I am also co-author of the GraphML Specification, one of the de-facto standard exchange formats for graph visualization packages.
