Controlled Vocabulary or Ontology?
• One-to One mapping relationshipStraightforward
Subjects: use controlled vocab
• One to Many mapping RelationshipHighly specialized

Which brings us to..• W3C Semantic Web
– “Web of data” –Ontology as processing tool interconnecting stand alone data sets
• Illumination Collection Study– Vocabulary interoperability
study• Wolfram-Alpha
– Computational knowledge engine that draws on multiple sources to answer user queries directly. http://www.wolframalpha.com/screencast/introducingwolframalpha.html
LSC 606 Executive Summary E McLean
"Semantic" interoperability is based on a precise and correct use of the formal RDF semantics embodied in the RDF graph data model and in RDF-based vocabularies such as DCMI Metadata Terms. Semantics…refers to formally stated relationships between terms and rules for using such statements to draw automatic conclusions (logical inference)s”.
