Sideline sole-proprietor for semantic web projects.- Proposed and implemented a simple but novel method for including semantic annotation in an HTML page, including a validation tool running on Google App Engine (http://turtlescript.trikelane.com/validator) and a client-side RDF/Turtle parser (http://turtlescript.sourceforge.net/)- This tool has been available as open source since 2009. In 2012, Turtle-in-HTML became a W3C standard that is interoperable with this project. (http://www.w3.org/TR/turtle/#in-html)
