Featured community member: Bob DuCharme likes to do interesting things with semi-structured data and metadata and then write about it. His interest in RDF and the semantic Web led to his current position at TopQuadrant, a provider of software for modeling, developing, and deploying semantic Web apps. Bob is the author of several articles and tutorials on developerWorks about Wikipedia query forms with semantic technology, DITA, XHTML 2, and SOAP. Bob has been closely involved with XML since it was SGML, especially XSLT, which is the subject of his Manning Publications book "XSLT Quickly." Other books he has written include Prentice Hall's "XML: The Annotated Specification" and "SGML CD" and McGraw Hill's "Operating Systems Handbook." Bob received his BA in Religion from Columbia University and his Masters in Computer Science from New York University. He lives in Charlottesville, Virginia with his wife and two daughters, who all ride horses, an activity that Bob has managed to avoid. Bob prefers to play the upright bass in Charlottesville's local jazz scene. His other main hobby is hipstergifts.com, an XSLT-driven Web site of the cooler stuff from on-line vendors who have affiliate programs.
