Jon Bosak
Occupation	Computer scientist
Years active	1996–2008 (at Sun Microsystems)
Known for	Development of the XML standard at the W3C, leadership in OASIS Universal Business Language Technical Committee

Jon Bosak was the driving force behind the development of the XML standard at the W3C. Between 1996 and 2008, he was employed by Sun Microsystems.

XML

Tim Bray, who served as one of the editors for the XML specification, highlighted Bosak's pivotal contribution to XML's widespread adoption:

In a message posted to the xml-dev mailing list in 1999, Bray further emphasized:

Upon Bosak's departure from the W3C XML Coordination Group in 2000, he was honored with a unique designation:

To recognize his visionary leadership, the W3C XML Plenary on February 10, 2000, granted Jon Bosak the permanent title "xml:Father" associated with the XML name.

The Universal Business Language

In 2001, Bosak spearheaded the formation of the OASIS Universal Business Language Technical Committee aimed at creating standardized electronic business document formats. He guided this committee through to the release of UBL 2.1 in November 2013 and remains active as its Secretary. The European Commission endorsed UBL for public sector procurement across Europe in October 2014, and it was subsequently published as ISO/IEC 19845:2015 in December 2015.

Metrological Studies

Bosak authored The Old Measure: An Inquiry into the Origins of the U.S. Customary System of Weights and Measures (2010) and wrote the article Canonical grain weights as a key to ancient systems of weights and measures (2014), both of which contribute valuable insights into historical measurement systems.

Bob Bosak

Robert Bosak (1925–1987), Jon Bosak's father, was a notable figure in early computer science. Beginning in 1947, he contributed to building the first computer on the West Coast before joining RAND Corporation in 1948 to work on scientific programming. In 1951, he became head of the Mathematical Analysis Group at Lockheed Aircraft Corporation. After a brief time sharing accommodations with Bob Bemer—known as "the Father of ASCII"—he returned to RAND in 1956 to lead programming efforts for the Semi Automatic Ground Environment (SAGE), an automated air defense system for NORAD that operated from 1959 until 1983. His contributions laid groundwork for contemporary air traffic control technologies. Additionally, he co-created the JOVIAL programming language and authored the seminal paper An Information Algebra.
