Q2: Need to follow direstions indicated in the questions.  a. Intended to compare capabilities of UML vs. RDF. Need to hop from UML to RDF in one step. The class diagrams given are only a small portion of application specification using UML. Think how to convert the rest to RDF!  b. RDF graph to N3 in one step. Intended to show elegance and simplicity of N3 vs. RDF graph ( vs UML).  c. Again, UML / RDF to XML not reverse direction.  d. Needed to: i. Embed class structure İi. Provide instantiation (made-up data). Q3: Opinion based on findings substantiated by references. Qs? Concerns?
