XML in the Wilderness

Published on

Presented by Joe Gollner at Documentation and Training West, May 6-9, 2008 in Vancouver, BC

The rapid emergence of the Web 2.0 has had a number of impacts. One that might be less obvious is that the Web 2.0 phenomenon showcases a number of important facts about the nature of content and the lessons we should attend to when designing content technologies. One of these lessons is the central importance of XML. There are also lessons for XML itself to be found in the Web 2.0 phenomenon and these ultimately point back to the original purpose of XML.
