Henrik Frystyk Nielsen

From Wikipedia, the free encyclopedia

Henrik Frystyk Nielsen (born 1 August 1969 in Copenhagen, Denmark) is one of the principal authors of the Hypertext Transfer Protocol (HTTP) specifications [1], HTTP 1.1, the SOAP 1.1 and 1.2 specifications [2],[3], and a frequently-cited authority on computer network architecture.

Nielsen received a Masters Degree in Engineering from Aalborg University in 1995.

Nielsen's Web work began at CERN, when he became Tim Berners-Lee's first graduate student, and shared an office with Håkon Wium Lie, the co-inventor of Cascading Style Sheets. It was at this time he began work with Berners-Lee on HTTP, and later joined Roy Fielding et al. Nielsen was invited by Berners-Lee to join the technical staff of the newly formed World Wide Web Consortium (W3C) in 1994. He joined the staff of W3C in March 1995, and continued work on HTTP and other Web protocol topics.

Nielsen joined the staff of Microsoft in August 1999, and began work on SOAP 1.1. Previous versions of SOAP had been proposed as an XML-based object serialization protocol, such as XML-RPC but through the input of Nielsen, Noah Mendelsohn, and others, SOAP 1.1 grew into a lightweight message-oriented protocol for exchanging semi-structured information in a highly decentralized environment. In 2000, Nielsen joined as an editor the standardizing effort of SOAP within the W3C XML Protocol Working Group which eventually became SOAP 1.2.

In 2003, Nielsen started an incubation project together with George Chrysanthakopoulos focusing on providing a new Web-oriented application model and associated programming model suited for highly concurrent and distributed environments. An output of the incubation is DSSP, a SOAP-based protocol that augments the Web and HTTP model with structured data manipulation and event notifications. By the end of 2005, the incubation moved into productization as Nielsen and Chrysanthakopoulos joined the newly formed Microsoft Robotics Group. In June 2006 the first version of the Microsoft Robotics Studio shipped to the public. Nielsen is currently working as a Group Program Manager in the Microsoft Robotics Group.
