As a user how do i add information to my public profile – assuming that i don know how to write RDF?
Usually information should be added to a profile using the best Web 2.0 practices, which in the end boils down to filling in forms, collecting interaction data, drag and drop (HTML 5 allows that in a much bigger way), etc…. The user should never be writing out any RDF in any format whatsoever – unless it’s an RDF Integrated Development Environment of course.
