What is taxonomy? “Taxonomy is the practice and science of classification” (wikipedia) Word comes from the greek word taxis – order, arrangement (lexical roots) Taxonomic schemes are usualy organized in tree structures using parent-child relationship “Hierarchical taxonomy is a tree structure of classifications for a given set of objects” (mathematical definition) Well known example of taxonomy is the Biological Taxonomy which classifies all plants and animals Examples from IT domain: File systems with directories Web sites with pages
- 3. Taxonomy in CMS Hierarchy of pages – how the pages are structured Types of pages – what kind of information pages hold Page attributes (meta data) TAXONOMIES ARE USED ALL THE TIME 3 general types: CLOSED (predefined, prefilled) OPEN (“folksonomy”, user tags) DYNAMIC (facets generated depending on the context)
