Midterm Exam 1

• Individuality is of paramount importance.
• Q1 Succinct survey of essential differences and
  similarities.
• 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
• Ii. Provide instantiation (made-up data).
• Q3 Opinion based on findings substantiated by
  references.
• Qs? Concerns?
