Math on the Web [items with personal involvement or interest only]: Math Working Group [1998-2016; co-chair July 1998 to May 2002; chair June 2002 - October 2003; 2003-2006 WG became an IG; co-chair 2006-2016] at the World Wide Web Consortium (W3C)
The Math Working Group was one of the oldest W3C Working Groups. During its first period of activity (1996–2004), it created and maintained versions 1 and 2 of MathML. During its second period (2006–2016), it created, among other things, MathML version 3 and saw it become an ISO standard.; MathML 3 (as ISO Standard ISO/IEC 40314:2016(en) Information technology; — Mathematical Markup Language (MathML) Version 3.0 2nd Edition June 2016) [co-author & editor]; MathML 3 (W3C Recommendation October 2010) [co-author & editor]; MathML 2 (W3C Recommendation October 2003) [co-author & editor]; Mathematical Markup Language (MathML) 1.01 (W3C Recommendation July 1999) [co-author & editor]; XML Entity Definitions for Characters (W3C Recommendation April 2010) [co-author & editor]; A MathML for CSS Profile (W3C Recommendation June 2011) [co-author & editor]; W3C Note on Units in MathML (November 2003); Some pointers to Information about Units
Math information sources (Sep. 2004): Math on the Web at the AMS 1996-2014, at http://mathontheweb.org to present [site maintainer; recently not well]; MSC2010 Wiki (Mathematical Sciences Classification, MR and Zbl) [site and wiki maintainer]; MSC2010 in SKOS form (Mathematical Sciences Classification, MR and Zbl) [site and wiki maintainer]
