Query: RDF annotation of Second Life objects: Knowledge Representation meets
  Social Virtual reality   We have designed and implemented an application running inside Second Life
that supports user annotation of graphical objects and graphical visualization
of concept ontologies, thus providing a formal, machine-accessible description
of objects. As a result, we offer a platform that combines the graphical
knowledge representation that is expected from a MUVE artifact with the
semantic structure given by the Resource Framework Description (RDF)
representation of information.
