The Authors

Bob Glushko spent many years in industrial research and development, technology transfer, and consulting with a focus that evolved from human factors in computing systems, to electronic publishing, and then to Internet commerce. He founded or co-founded three companies, the last of which was Veo Systems in 1997, which pioneered the use of XML for electronic commerce before its 1999 acquisition by Commerce One. From 1999-2002 he headed Commerce One's XML architecture and technical standards activities and was named an "Engineering Fellow" in 2000. In 2002 he became an Adjunct Professor in the School of Information Management and Systems at the University of California, Berkeley where he is the Director of the Center for Document Engineering.

Tim McGrath has a background in information systems design, specifically in the area of trade and transport systems. In 1990 he co-founded Transport EDI Services (TEDIS), which grew to be a leader in innovative Internet services for EDI in Australia. Apart from spending the past three years writing this book he has been the chair of the Universal Business Language Library Content subcommittee.

Bob's work in Silicon Valley in the "new economy" of moving bits around the Internet was perfectly complemented by Tim's expertise in the "old economy" of moving real stuff around in the physical world. Bob's efforts with SGML and XML for document analysis were matched by Tim's with EDI and data modeling. It seemed natural to work together to create a coherent and comprehensive approach for Document Engineering that builds on their unique combination of perspectives and expertise.
