Ivan Herman

Who am I?

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 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 World Wide Web Consortium (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 “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 publications 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. I was, between 2007 and 2014, also member of SWSA (Semantic Web Science Association), the committee responsible for the International Semantic Web Conferences (better known as “ISWC”) 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.

Some personal data

I can also be identified through the non-information resource URI: http://www.ivan-herman.net/foaf#me (when dereferenced, the URI redirects to this page for (X)HTML, and to the generated foaf file otherwise). My foaf “friends” are listed in a separate RDF file.

This file is in HTML+RDFa 1.1. Running the file through an RDFa processor yields the corresponding foaf file in RDF/XML file in RDF/XML or foaf file in Turtle file in Turtle. I have borrowed and adapted the ‘tranquile’ style of Dave Shea from the CSS Zen Garden site.


If I had the patience, I would do this in a more 'HTML' way to display it, but I do not really want to spend my time on that… Information Visualization PREMO Manifold

Ivan Herman, 2014-03-01. A detached signature for the generated foaf RDF/XML document is also available to prove the correctness of these data. (My GPG public Key has a length of 1024, and the following fingerprint: 31DD 8BBF 6057 1601 659E E95F 751D E143 343F 1A3D. The key belongs to Ivan Herman )
Unfortunately, time to time spammers get hold of one of my email addresses and send out a bulk spam with that forged name. I cannot do anything against that. Note, however, that I usually sign my emails with GPG (except when I use my mobile phone or a web mail interface, but I use those relatively infrequently). Ie, if you get a mail from me without a signature, it may be considered as suspicious…
