Semantic Metadata: A Tale of Two Types of Vocabularies
Saturday, October 27, 2012, Half Day 1:30pm-5:30pm (seminar fee)

Semantic metadata is metadata that is expressed using a standard syntax that can be commonly processed by applications and tools. There is always an implied statement in any description or "classification" of an object, for example, <News Item><Topic><US Presidential Election 2012>. This is a subject-predicate-object triple, or more specifically, a class-attribute-value triple. The first two elements of the triple – class, attribute – are metadata elements with a defined semantic relationship. The third element is a value, from a controlled vocabulary. This seminar will focus on: 

  1. The two types of vocabularies involved with semantic metadata, the class-attribute vocabulary, and the value vocabulary. Examples of standard metadata vocabularies such as Dublin Core and FOAF, and canonical lists of named entities (people, organizations, places, events and things) especially well-branded names such as products and services will be shown.
  2. Standards and tools for vocabulary management. Examples of standards such as RDF and SKOS, and vocabulary management tools that work with RDF and SKOS such as Protégé and ThManager.
  3. How the two types of vocabularies are enabling the growth of the linked data cloud, and what this means for online business, publishers and consumers.
