Symposium on Markup Vocabulary Customization
Participant Biographies

Syd Bauman
Syd Bauman was introduced to the world of markup languages through the world of computer typesetting. He became interested in SGML just prior to its publication in 1986, but did not start seriously engaging with it until late 1990 when he started working with TEI P1.1. He has since become immersed in markup, XML, and TEI.

Syd is a Senior XML Programmer/Analyst at the Women Writers Project, part of Northeastern University’s Digital Scholarship Group, where he does not actually do much programming. When he does it is usally XSLT designed to read TEI. But regardless of language, Syd’s programs are always copylefted.

Syd often teaches XML, TEI (in particular, TEI customization), and XSLT. He served as the North American Editor of the TEI from 2001 to 2007, and has been an elected member of the TEI Technical Council since 2013.

David J. Birnbaum
David J. Birnbaum is Professor and Chair of the Department of Slavic Languages and Literatures at the University of Pittsburgh. He has been involved in the study of electronic text technology since the mid-1980s, has delivered presentations at a variety of electronic text technology conferences, and has served on the board of the Association for Computers and the Humanities, the editorial board of Markup languages: theory and practice, and the Text Encoding Initiative Technical Council. Much of his electronic text work intersects with his research in medieval Slavic manuscript studies, but he also often writes about issues in the philosophy of markup.

John M. Boyer
John Boyer is an IBM Distinguished Engineer and Master Inventor. He joined IBM in 2005 via its acquisition of PureEdge Solutions. While at PureEdge, John undertook graduate studies in theoretical computer science, earning his Ph.D. in 2001 from the University of Victoria. John has over two dozen refereed journal and conference publications, over 30 granted patents, and numerous other publications of professional articles and industry standards. John has served as Chair of the XForms working group, Editor of XForms, and Editor or Co-author of XML Signatures, XML Canonicalization, and related W3C Recommendations.

Hugh Cayless
Hugh Cayless is Senior Digital Humanities Developer at Duke University, where he provides architecture, design, and programming support for the Duke Collaboratory for Classics Computing (DC3). He has served as an elected member of the TEI Technical Council since 2012 (as its Chair from 2015-2017), and he is a founding member of the EpiDoc Collaborative. Hugh earned a PhD in Classics and an MSIS, both from UNC Chapel Hill. His research interests focus on digital critical editions and Linked Open Data.

John J. Chelsom
John Chelsom is CEO of Seven Informatics Ltd. He trained as an electrical engineer before gaining a PhD in artificial intelligence in medicine. He has been a Visiting Professor in Health Informatics at City University, London and the University of Victoria, Canada. As Managing Director of CSW Group from 1993 to 2008, John was responsible for implementation of XML workflow and production systems for many major organisations, including the British Medical Journal, Jaguar Cars and the Royal Pharmaceutical Society.

The Case Notes product developed by CSW was based on XML and other open standards. In 2003 the UK government chose Case Notes as the primary clinical system in the national architecture for a shared electronic health record covering the 55 million citizens in England. In 2000, John founded the XML Summer School and continues as a board member and lecturer in this annual event.

Since 2010 he has been the lead architect of the open source cityEHR product — an XRX (Xforms, REST, XQuery) health records system currently used in a number of hospitals in England.

Sam Wilmott
Sam Wilmott designed his first programming language in the winter of 1967-1968 and was using early non-standardized markup languages in the late ’60s. Since then he has led the development of typesetting/text-formatting systems for the Canadian Government Printing Office (in the ’70s) and for a major real-estate company (in the ’80s), implemented one of the first SGML parsers (which was also the first pull-model markup parser), and is the originator of the OmniMark programming language (in the early ’90s), with its strong support of SGML, XML, and text transformation.

After leaving OmniMark, Sam worked in the XSLT world: he contributed to the implementation of an XSLT compiler and worked as an XSLT programmer and analyst (in the early 2000s). Currently he is largely retired, happily married, does voluntary work locally and walks a little dog every day, but in spite of his advancing age, he is nonetheless working on new programming language ideas for markup language and text processing.
