Review for the Exam #1 – March 10, 2010 l NVD database – use of semantic technologies l Confidentiality, privacy and trust and applied to semantic web l Secure third party publishing of XML documents l Inference problem and semantic web l RDF and Security l OWL and Security l Ontology alignment and security l ROWLBAC – question on paper l Platform for privacy preferences l Assured information sharing l Web Services and Security l SAML, XACML l Extra credit question

Policy for Second Half of the Semester l Because this is a PhD level class, during the second half, the students will be reading papers and presenting in class. l Students will read all the papers assigned; the paper will be posted in the Introduction section on the Monday prior to the following week (e.g., March 22 for lectures on March 29 and March 31) l One or more students will be selected at random and requested to present the paper and the entire class will participate l While it is unlikely that a student will be selected twice, it is not improbable l If a student is absent without a valid excuse prior to the class (e.g., a student is sick) 5 points will be deducted from the final score if a student is not present to present the paper.
